Ford 6.0L Power Stroke Diesel :: 2005 - Stalling When Hot Getting Low ICP
Jan 30, 2017
I've been having this problem for a while and seem not be able to get anywhere.. so at first my truck had a stalling when hot getting low icp which lead to a new hpop, couple injectors, dummy plugs, icp.
Ever since I got the new hpop, now when it gets to operating temps the low pressure gauge drops, and once you get on pedal it goes back up then eventually stalls. Then have to wait till cold.. the low pressure gauge will not drop till oil is warm. Does it sound like a low pressure pump?
It's a 2005 6.0 with 213,000

I literally just got this truck 1 week ago. '05 6.0 F250. I have read numerous other threads and have not found an answer. I will start from the beginning.
I was driving on the hwy and once the engine is hot and I am over 55mph the truck feels like it wants to stall. The rpms drop and come right back up. Its like a 'hiccup'. If it starts to act up and I pull over it remains at idle and not stall. Once i get back on the hwy IF I go over 55mph the truck will stall and I will not be able to start until cool.
After doing some reading through the forums I replaced the IPR on the HPOP.
I tested the high pressure oil system. I took off the valve covers and tested both the right and left side individually, with the IPR valve open and close; cannot find a leak.
I took the fitting off of the top of the HPOP and tested with air there as well. I only hear air out of the weep hole in the back behind the gear on the pump.
I took the oil pump off and charged the branch tube with air, no leaks.
I checked all the dummy plugs. They have been already replaced with the upgraded ones and the orings all looked good.
I took the upper half of the standpipes out - look good, orings looked good. I was unable to get the lower half of the standpipe out on the passenger side due to the air box and the driver side only the top half came out when unscrewed from the oil rail.
I put it all back together with 2 new batteries.
I started it, (started cold), drove it 25 miles and it stalled, let it cool down and it started. Drove it 20 more miles and I pulled into a parking lot and I shut it off, and it started right back up 3 times. When it shut it off on the highway I unplugged the ICP sensor and it did NOT start.
It runs fine until I go over 55mph then I am getting the same stall issue. I can drive it around under 50mph and have no issues. I drove it under 50mph and shut it off a total of 3 times and it started back up no problem. If I drive it over 55mph rpm gauge drops and then comes right back up and IF it stalls I cannot start until it cools. Once it stalls out, If I try to crank on it, my IPR is 84.8% IPC - 99-120.
I am using a Scanguage II at idle:
ICP - 18.5
IPR - 585
FMP - 47.5
My FICM Voltage stays between 12.5 - 13.0 while running.

I have a 2003 6.0 and I am havi g problems with it stalling once getting up to operating temps. I found a leak earlier after the engine stalled, it was leaking pretty good around a drop every 2 seconds but stops once the engine cools down some. I noticed the oil dripping from under the oil pan.
Can this be the cause of the engine stalling? Or just another problem? If it can be the cause where can the leak possibly be coming from?

My 6.0 stalls out when under load above idle intermittently. When it stalls, if I release the gas pedal and tap it, it usually catches again but not always. ICP is strong and doesn't seem to waiver when it stalls. Engine runs much better when oil comes up to about 180. Oil / water temp spread about 5 degrees.

My 6.0 excursion has been stalling at stops, and in slow traffic for the past couple weeks. I've also had an oil leak (see my most recent post w pics)
Could those two things be related? The compression gauge shows its okay, What else could be causing the stalling? I just got a lead on a good diesel mechanic in springfield missouri (30 ) minutes from where i was today with the excursion, I don't know if i should risk a 2 hour drive back to springfield to take it to him.
I had the oil changed at a local shop last week and the tech told me the oil pan was leaking oil, but you can see on the pics I posted that that oil seems to be on hoses above the oil pan. So I don't know if the leak is coming from above or what.

So any ICP sensor been proven bad but i was not leaking oil? The symptoms of my truck sound similar to a bad ICP...fluctuating idle, surging, stalling, but it does run and start. IT tends to start acting up when it hits operating temp.
I have an 04 and the ICP sensor is in the easy spot to get to on the valve cover vs under the turbo (that's awesome) so its an easy swap. but just wondering if there is any way to test it over simply swapping it. I do not have a monitor yet but a dongle is on order and will get the torque app for my tablet.

I have a 2006 6.0 F350 that has started stalling intermittently. Truck starts right up after a few minutes and otherwise runs great. I'm getting trouble code p2617 (crankshaft position sensor). Reading on some of these forums it sounds like it could be a whole array of things causing this. Would this sensor be a logical place to start or what, if anything, should I look at before getting any parts?

I have a 2011 F 350 super duty 6.7 diesel. Occasionally while driving I am getting a cackle from the engine and it sputters and sounds like and feels like it's going to stall out. There is no power. It only happens occasionally. It happens mostly when Im driving, not accelerating from a stop. Example would be driving along for a while then try to accelerate off a ramp on to interstate. I brought it in and of course the excuse is we can't get it to replicate what I discribed. They did adjust something in the transmission shifting pattern. I get irritated when I paid for a loaded f350 diesel lariat and it has issues like this.

2004 F250 Powerstroke Diesel 6.0L ... 90,xxx miles
Symptoms : Within the past 10,000 miles the truck has begun exhibiting the following problems, sometimes in conjunction with one another and sometimes just independently of one another:Stalling on the road at low speed / low engine RPM.
Throttle pedal becomes completely unresponsive. Stabbing the throttle pedal repeatedly sometimes causes it to return to operation. Sometimes the engine must be shut off and re-started to return throttle pedal to operation.
Rough, surging, stumbling idle at rest. Will crank but not fire occasionally. Problem has become worse as of late. Repeated attempts at starting the engine usually result in success after much, much retrying.
Work Done : Local Ford Diesel technician replaced the EBP sensor, replaced the EGR valve and re-flashed computer with latest software -- all under warranty. Problems still persist.
Peculiarities : We have tried driving the truck with the EGR valve disconnected and with it connected, both at the technician's request.
With the EGR valve disconnected the truck usually starts fine but still stalls out at low RPM / low speed. Fuel economy is also cut by nearly 50% with the EGR valve disconnected. Really couldn't afford to keep driving the truck like this.
Technician speculated that if the truck continued to die with the EGR valve unplugged, it meant that the computer or fuel pump might be bad. ????
It also seems that the stalling problem manifests after the truck has been driven at highway speeds (65-70mph) for at least a period of 20-30 minutes. Stalling usually happens as soon as we make an exit off of the highway and begin to slow down to make exit. As in foot off the throttle pedal. Engine RPM drops then stumbles then stalls.
I wonder if this is a problem with the HPOP or ICP system.
Specifically I wonder if this is a cracked quick release fitting that allows oil pressure to fall after the engine heats up and oil viscosity thins out with the heat. Once the engine cools down sufficiently to thicken the oil, the HPOP finally gets enough oil pressure to allow the engine to fire up again.

I have a 2004 Excursion with a 6.0 Bought the truck already studded, EGR deleted, and a 54V FICM. When I bought the truck it had a hot stall, no restart problem. Found the high pressure oil leaks and resealed them by replacing the #3 injector and replacing the top injector seal in the #4 .Oil pressure reads very good now and I drove the truck for a couple weeks problem free.
Truck started smoking (white to gray) and felt like it had a miss. No misfire or contribution codes. Truck failed the bubble test and I narrowed the leak down to the passenger side by removing the banjo bolt
Banjo bolt at the front of the passenger head
Found the #3 injector loose...the copper washer
Copper washer had disintegrated/melted and appeared to be stuck to the side of the injector. Scraped off easily enough, cleaned up the injector and injector cup and reinstalled the injector with new O-rings and copper washer.
Put the truck back together and still smoked the same and still felt like it had a miss. Ran KOER test and found sometimes a contribution code for #2 and sometimes #6 .
Drove the truck to work and it didn't feel down on power...mostly just smoked and rough idle...but on the way home there was a lack of power and just as I pulled into my driveway the truck stalled...wouldn't restart. FICM voltage was good, high pressure oil read over 900, IPR was holding around 40%.
Pulled the secondary fuel cap
Secondary fuel cap to run another bubble test...there was no fuel in it...completely empty. Started to think that I had a fuel feed problem. Hooked up a fuel pressure gauge
Fuel pressure gauge and drove the truck again...pressure wasn't great (45 lbs) but never dropped below 42...not even when it stalled. Pulled the cap again...dry again...yet the truck read fuel pressure.
Research showed that I was possibly pressurizing the fuel system with combustion pressure and that was possibly displacing the fuel from the fuel system. This would explain the run for a few minutes, then stall and no restart for a few minutes...I'm assuming that the pressure would bleed off and the fuel pump would start over.
Still failing the bubble test and still pointing to the passenger side. I pulled and recleaned the injector and cup...new orings
oRings and copper washer. Bubble test again...fail.
Pulled glow plug from #3 , failed bubble test still.
Pulled glow plug from #1 , failed.
Pulled #5 , failed...pulled #7 ...failed.
With no glow plugs in the passenger head I am still bubbling up to the fuel filter housing. Pulled the banjo bolt from the front of the drivers side head...no more bubbles.

Don't know where to start so I'll ramble!
2005 f350 with the 6.0. Crew Cab, 8' box, 4x4 with DRW. I use it only take the boat to the launch 5 minutes away once in a while and to pull car trailers every other week. Majority of driving is on the highway and average trip is about 300 miles. Low power and now no start.
No codes. I do have a scan Gauge and can provide data.
Was running this week, but has had a lack of power for some time. I had put 2 new injectors in last summer. Also updated dummy and stand pipes. Blue spring. Also new IPR at the time.
Ficm board was replaced in March.
New injector harness last year. New Glow plug harness last year.
Coolant level is fine and none being lost.
CAC hoses appear fine, no cracks.
No boost. But newer MAP sensor, hose not cracked or plugged and nipple on intake is clear. Put the MAP sensor last year and it didn't make a difference.
Turbo was rebuilt 2 years ago.
IPR has to hit close to 80 before boost hits 12-15. But it takes a while to get there.
Now won't start.
Yesterday am it was about 30 farenheit and no start. Last year would start no problem.
Batteries are fine. tested.
Engine fires within 3 seconds, but doesn't want to run.
ICP is above 500. climbs as I turn over.
Fires only in first few seconds and then nothing while I keep cranking it. it is cranking fast enough though.
Now...I see IPR will hit 84.7% and then 14.8%. Not good!
When running it sits in between.
FICm voltage is 48.5 key one and 47.5 when cranking.
Wondering if possibly IPR screen is plugged? Or would CKS or CPS cause issues? I recall reading about pulling one of them and cleaning rust off of it? Also...should mention, no EGR reading on scan gauge..never was either. I had checked and cleaned egr valve before. it was clean when I pulled it and not sticking.
Intake had been cleaned 2years ago. Also, on occasion, while pulling up hill, I would get power! Black smoke and it would race up a hill like it's supposed. Then it would go back to no power.
Also...if I pull the MAP hose from the intake nipple, should I feel suction from the intake? There doesn't appear to be any air coming or going from the nipple.

I have 2005 f350 with 365000 km on it I have it for one year and don't have a problem till last week. I was pulling van on dolly uphill and sadden lost pover, so I stopped and check oil leaks ,transmission .... But everything looks ok in couple minutes start engine and go home (10 km). Change fuel filters trans filter, looked good for 50km and star losing power again and doesn't want start. So I skan and its show me next numbers.
Key on engine off
Ipr-15%
Icp-0psi
Icp-.26v
Ficm main power-47.8
Ficm logistics power-14.5
Ficm sync is good
Engine crank
Ipr-85%
Ficm main power-48.0
Ficm logistics-12.5
Icp- 625psi
Icp-.77v-1v
So what I have to do?

2005 F250 SD, Crew Cab, Diesel 6.0L...
Hauling my jeep (close to 16,000 pounds all in F250+trailer+jeep) on a highway going a little over 70mph up a hill when I seemed to have lost some power and the check engine light came on. The turbo PSI was well over 20PSI (according to the gauge in the dash). I have a Scan Boss but I have not been monitoring turbo boost PSI.
I was only 10 miles from the final destination so I continued without stopping. It seemed that the turbo was limited for the rest of the trip. Later in the evening, no more check engine light but I haven't really driven the truck since then.
What do you think the problem was? What should the course of action be?

I had this truck for two months no problems yesterday went on a small trip about 50 miles in on ,the hwy. I start seeing some smoke and then no power turned off & on engine several times a little hard starting no power at all I put the pedal to the floor It barely moves ran into another super d. guy he said fuel filters , I turned around and crawled back home and changed fuel filters still no power. no codes "don't no where to start".

I got a 2005 f350 6.0 deleted and studded with air dog 2 4g pump, 125k miles. It started running rough then just died all within a few miles tuner showed code for injector 6 and ficm towed into ford dealer didn't have time to mess with it. They said ficm was bad had them replaced it then they said i need whole new fuel system lines, harness, pump, sending unit , tank the whole 9 yrds. Which i thought was uncalled for so i called up airdog which system i had on there and they laughed and said ford garage is full of bs that they will upgrade my pump to the 4g and new harness.
So I took that stuff to the garage had them swap it out and now they said come get the truck they won't work on it anymore that now it needs 3 injectors and they won't touch it with aftermarket fuel system on it. So i go to drive it home and it starts but runs rough and u can hold it to the floor and it won't budge bearly idles up and builds no boost my tuner is showing injector 2,3,4 now which wasn't a problem before i took it into the garage. So im not sure what happened to cause this all to happen but before i sink any more money into it is the 3 injectors enough cause to make it not build boost now.

I have a 2005 F-350 Lariat, FX4, CrewCab, with an 8ft Bed if any of that matters. Currently sitting at 191,000 miles and 4,500 Engine Hours I just started running into some issues that I cannot figure out. To start with here is a list of all the mods and prior maintenance that I've done to my truck over that last 6+ years that I've owned it.
I purchased the truck in 2010 and had no issues whatsoever for the first 3 years.....then it all started. While pulling a camper home from vacation "still bone stock" the truck overheated and by the time I realized it it was to late. I ended up blowing a head gasket cracking a head and blowing a hole in my coolant reservoir from the heat & compression of the engine in the coolant system. So to the shop it went.
All of this was done at the same time at just under 4,000 engine hours:
1) Both heads were sent out to be pressure tested "which is where the crack was found", so 1 replacement head and the other trued up and tested by the machine shop
2) All 8 injectors replaced with Airtex/Wells New/Reman
3) ARP Head Studs
4) BPD EGR Cooler
5) New Stock Coolant Reservoir
6) New Stock Oil Cooler
7) Motorcraft Coolant & Oil/Oil Filter Change
8) New Serpentine Belt
After getting the truck back I installed some upgrades that I had wanted but didn't want to do until I had head studs. 4" Turbo back Diamond Eye Performance exhaust, Bully Dog GT Tuner with an EGT Pyro, coolant changed to Caterpillar ELC, Sinister Diesel coolant filtration system, new Optima batteries "I hated them",
Forward a year with no problems I had a crank but no start. I ended up having a bad IPR. A buddy rebuilt the turbo since I had it out and it was leaking. He apparently did something wrong because it took its own life sometime after. So a brand new stock Garrett Turbo with a Wicked Wheel 2 & I changed the IPR "don't remember the brand." Also replaced the factory paper air filter with a cleanable one from AFE that fits in the factory cold air intake.
Little more time and I started to have some overheating issues again, luckily the Bully Dog was monitoring and I had alerts set up so I caught it way before it caused any serious damage. Turned out the fan clutch wasn't working. So I replaced the Water Pump with one from dieselsite.com that has a steel impeller, also replaced the computer controlled fan clutch with a 7.3L mechanical fan clutch and an adapter from BPD.
After that the batteries I hated were replaced. I installed Oddssey Extreme 950CCA ones, a new 185A alternator from FICMRepair.com as well as the complete battery wiring interconnect kit. Did the blue spring upgrade. Replaced my FICM with the BPD 6 phase at 54V setting. Also I changed my starter to an 6.4L Ultima one from O'Reily Auto to bring me up from that slow crank of the 6.0L at about 150RPM to the 225RPM of the 6.4L.
So now on to the current issue. This has happened in the last month and may be related to the issue. I had some small coolant leaks and wanted them fixed. Pressure tested the system & found the radiator and timing cover gasket leaking. I installed a new stock radiator and lower radiator hose. Had the shop do the gasket and a serpentine belt due to cleaners being all over it. During replacement of the timing cover gasket my mechanic found that the LPOP gears had some damage as if something had be in there at one time. Not sever damage just minor. LPOP replaced with brand new one from Ford.
After I got the truck back it was fine for 2 weeks, no leaks or any problems whatsoever. Then I noticed a hesitation as I was leaving work at idle. You could see the RPM's moving up and down by about 50 as it sat there at idle. It got really bad and eventually stalled on me. It fired right back up and ran fine after. I was thinking water in the fuel or just maybe old fuel because it was kinda old and I was at 1/4 of a tank. I went and filled up and it ran great all the way home. Day or so later same thing. At idle you can see the RPM fluctuating and while driving it feels like it has no power at times then it goes away and runs fine. So I changed both fuel filter with Motorcraft ones and put in a new oil filter. It is the Wix brand but I've be running it for years with no issues, one was also in it way before this issues started. The oil has about 2,000 miles on it currently. I verified fuel pressure at idle to be at 70PSI. I tried unplugging the ICP at idle with no change in the hesitation. So I plugged in my SG2 and started to see if I could see anything out of the ordinary.
OAT - 60 Degrees F
KOEO Engine Cold - FMP - 54.5V, ICV - 0.25V, ICP - 0, IPR - 14.9
KOER Engine Warm - FMP - 54.5V, ICV - 0.82V, ICP - 576, IPR - 23.5
Cruise at 40MPH - FMP - 54.5V, ICV - 1.14V, ICP - 965, IPR - 32.9
Cruise at 50MPH - FMP - 54.5V, ICV - 1.42V, ICP - 1,190, IPR - 38.0
Cruise at 60MPH - FMP - 54.5V, ICV - 1.27V, ICP - 1,143, IPR - 37.2
While driving this issue comes and goes very randomly. The only parameter I notice changing alot is the IPR. It jumps around a lot and sometimes it will go to 85. I know that this isn't a good thing so I am going to change the IPR later today or tomorrow. I already had a brand new Motorcraft one to put in, plus at the very least I want to look at the screen. I had read somewhere that there could be air in the oil system and that if you run at a high RPM it can remove this air. I never seen any bubbles or anything on the dipstick. My brother ran the truck for me at 3,000RPM for 5 minutes. No hesitation during the test but he didn't have the SG2 plugged in so I don't know the parameters during the test. I thought that it worked but then it came back after a few miles of driving. The above parameters are from this mornings drive home from work.

05 6.0 deleted and studded. 170k fresh filters and oil, no CEL or codes.
This has happened 3x in months, so it intermittent. Truck will start fine cold, except for this last episode ....
Truck starts right up, idles correctly, speed bumps up if its cold enough to trigger the high idle. About mid way through its warm up, at approx 130-140 idle falls off, barely runs. Almost knocking. Black smoke if you give it throttle. Has no power when its doing this. Truck will not move and almost dies in gear. Give it til 185ish degrees then pooof! All good.
However 2 days ago it wouldn't start. Cranks but won't catch. Stumbles and dies. Finally got it to start after setting the charger on it. I killed it. But this time when it started it was straight into its rough idle, no power...until about 180. I switched it off, restarted it and it was totally fine
Ficm is 47-47.5. Every now and then I see a 46.5 for a split sec
Hpop is 700-800cold cranking.
Not sure what else to look at.
Moto craft filters.
Amsoil 5w-40
Archoil in the fuel and oil
Twc3 at every fill up.

My uncle bought an '05 that stopped running one day. He was driving down the road and engine lost power. He was able to coast into his driveway. Unfortunately, it's been 10 years since I've work on a 6.0 and no longer have any of my computers.
He did state there is no check engine light. He's going to change the filters today / tomorrow. I'm hoping to make it down there this weekend to look at it, but what to look for. Even more unfortunately, we really don't have any specialty tools or gauges.

I've got an 05 EX 4x4 150k miles. Stock tune, EGR delete only ....
Driving along and everything was good plenty of boost no power issues. Got off the freeway and truck just stopped making boost. So I messed with it for a couple days. Cousin with a Mac scanner flaked on me so I was stuck using Edge gauge cluster and trying to trouble shoot.
NO CODES, No smoke, EGT's rise and truck seems like it is lean. Boost has fluctuated between 4psi to 11 psi. What should MAF be at idle?
ICP has been consistent with whatever boost levels were being made.
FICM 47.5
New MAP tube/nipple cleaned
New MAF
Clean Air filter
New fuel filters
VGT actuates
Accel ped in spec
Turbo spins free
New hot side CAC boots

My 05 F350 will not start hot, occasionally stalls when hot as well. Starts immediately when cold and runs smooth as silk. Truck has 138k miles on it, I bought it studded and deleted, running 5w40 Rotella T6 with Archoil. Some history on the issue: Started out with a rough idle, found low FICM voltage along with a bad battery. Replaced both batteries and FICM, problem fixed. Soon after developed a misfire with a cyl 5 imbalance and injector code, replaced all 8 injectors which fixed that issue.
About 2 months ago I had a no start problem, turned out to be a bad ICP, replaced that and the harness and was all good for about 3 weeks. That's when it started becoming hard to start when the motor was warm, and then no start at all when hot and would stall occasionally at idle, wait an hour and it'll fire right up!
Ran the air leak test, found a leak on the right bank standpipe, replaced the dummy plugs and standpipes, no start still remained. Went on to replace the IPR and STC fitting which didn't work either. Now it throws a P2285 code, low ICP. Ran the air test again and I don't hear any leaks. HPOP seemed to have good compression turning by hand.
