Ford 6.0L Power Stroke Diesel :: 2006 - Hesitates - Hard Start?
Mar 10, 2015
I have a 2006 f250 with a 6.0 and I am having some issues with a hesitation and lose of power. The hesitation is worse when under load and other times is not so bad. Also it is non existent at higher RPMs (2500 and up). I changed the egr valve 2 months ago and it seemed to fix the issue (95%) but now it is running bad again. I used Hot Shot oil additive 2,500 miles ago and I changed the fuel filters and changed to 5w 40 Rotella synthetic oil, nothing has changed. I had the FICM changed a year ago with new software updates, still didn't fix it 100%.
Now I am having a "hard" start issue. It takes a bit for the truck to turn over. My batteries are 12 months old and I just replaced the alternator so I am not sure how to proceed.
I did just buy a Scangauge II and I am still figuring out how to use it. It says there is no codes.

I have a 2006 F350 6.0L. That is Having trouble starting after it is warmed up. Ive been told multiple things it could be but the one ive been told the most is the Stand pipe or dummy plug in the oil rail having a small leak. Is this correct? Or is there something else i need to Check??

I just picked up a 2006 F250 6.0. It was having hard starts. Anyways before I started using it I started tearing things apart cause I knew for sure the turbo was leaking so that had to be resealed. I just picked up a 2003 turbo today for it out of a used truck that had 144000 kms on it. (was in an accident). I am gonna post up a few pics here of the engine bay area, there is a huge amount of old oil I believe to be, I am wondering if it was a leak or spilled oil. I am going to be cleaning this up. Putting 03 turbo in here, doing a service and then plug my Tablet with torque pro and post up some numbers and see how healthy she is. Before I post any pics Is there a way to make these pictures clickable instead of them taking room up on the page?

07 6L gave me a fit the other morning. I spent the night in the mountains Saturday night. Sunday morning was -5. With no place to plug in the block heater. When I started it it bucked and hawed and didn't want to run... It keep surging for a while and finally smoothed out after about 3 mins... Is there an additive that will work for this for the times there is no place to plug in? Oil additive or fuel additive?

Fuel injectors do this? They are off a 2006 Ford F350 dually with the 6.0 diesel motor! Have replaced all 8 fuel injectors got back drove for 200miles and fuel injectors 4 and 8 were throwing codes changed them out and high pressure oil pump oil coolant deleted egr valve changed the ipr valve feed tubes to the oil rails. replaced the FICM. Yet again drove for 2 days about 200 miles again and shut down (stalled) misfiring hard start. and now fuel injector 4 is throwing codes again. Have not drove it since we got it home from the last stall out which was a few feet from our drive way and we towed it home.

I have a 2006 F-250 4x4 with no cat, and no egr but the valve is still connected. It has about 146,000 miles. Just recently when warm, it has a slight miss every once and a while when stopped and in gear. Just a slight drop in RPM then recovery. Its mainly used on the highway and 99% of the time I set the cruise and its smooth as silk. Every once and a while I feel it stumble once or twice, recover and it is fine for the next 80 miles with no issue. It started as once every few trips but now It seems to be happening at least once every other. I use Motorcraft filters (maybe 6K on the fuel filters) and rotella oil. My scangaugeII shows no codes and no Injector pressure issue (1200-1400 at 75 mph depending on grade) and the FICM voltage stays between 48.5v and 49.0V. What should I check?

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 removed all 8 injectors because my truck felt like it had a dead cylinder one morning after I did oil change and filter and fuel filters. Truck ran great the day of the fluid change. The next morning however truck was hard to start no power at all nothing. Felt like a dead cylinder so removed all 8 injectors and ohm them all ohm at 0.4 to 0.5 except number 4 injector it ohm at 0.4 and 0.7 that's not in spec right or am I wrong? Do I need a new solenoid? Keep in mind tho number 5 and 8 injectors had contribution codes but they ohm good. So I'm going to tear the injectors apart and see what's what. But my question is do I need to replace number 4 injector solenoid?

I bought my 04 6.0 from my parents a few years back and had it gone through as soon as I bought it. I got it studded, a new hpop, new oil cooler, 8 new Alliant injectors, and an sct livewire. A few months later my oil temp kept getting high and eventually it caused an injector to go out. Took it back to the guy who originally did the work and he warrantied it.
He said the oil cooler got clogged up on the coolant side. Replaced an injector and the oil cooler and it ran for another couple months before doing the same thing again. Had the oil cooler and injector replaced again and it ran fine until the number 7 injector went out and I had to replace it myself since the guy who was doing the work on my truck decided to pack up his shop and leave basically overnight.
When I got under the valve cover I noticed that the number 7 injector pigtail was different colors than the other injectors so I'm not sure what kind of work had been done to it after all, if he'd been mixing injectors or what, all I know is what he told me he had done. The truck currently has 157k on it. whenever I go to start it my injection oil pressure spikes to anywhere from 1600-1800 and the truck attempts to run but then the truck falls on it's face and the injection pressure will not get above 350-400 for about 10 to 20 seconds of cranking.
Then the oil pressure hand on my dash moves and the injection pressure goes up again and the truck cranks. After the truck is running it has a miss that most of the time goes away as the truck warms up. Im starting to believe that maybe the hoop is going out again but I'm unsure. I'm a heavy diesel mechanic so the huei injection system isn't my forte, but I do have access to just about any tool needed.

2003 Excursiom 4x4 Limited
My first Diesel. Runs and drives great. Torque Pro app only showed coolant temp at 188. Would not show oil temp. Hard to cold start. New injectors. Has a programmer. He is asking 12K. It has 209K miles.
It belongs to a friend of mine and he rarely drives it. It stays under a cover most of the time.

I'm new to diesels. I just bought a 2004 F250 with the 6.0 V8. I have the high and low circuit, contribution codes on cylinders 4 and 8. I've only had the truck for a few days but I've been reading a ton. The symptoms are hard start, rough idle/shaking, no power when cold. When it heats up and I'm over 2000 RPM it seems to be just fine. Even when hot and below 2000 RPM it does ok. I've check the FICM. It reads 48V with key on and 48V running. My plan is to do the following:
Change the Fuel Filters
Change the oil filter
Change Air Filter
Change oil with 5-W30 synth and I have both Hot Shot/Rev-X
If that doesn't work, I'll replace the two injectors. How does that sound.

I have a 2006 that shuts off in a hard pull, if I wait 3 minutes it starts again. I hooked up my scan tool and when it dies and I crank it it only builds 200psi oil pressure, let it sit it builds enough pressure to run fine. If I dont push it over 3500psi for more than minute it wont die pull a hill it dies again. Is it the hpop or an o-ring.

I have experienced a hesitation on my truck since I purchased it 6 months ago. I get a one to two second hesitation at take off from a stop. I have checked the back pressure tube and the one that goes to the turbo controller no problems. I have a Edge CTS programmer that only shows ... for EBP.

The last couple days the truck has been a hard start in the morning. about 28 deg F. I thought the glow plugs were getting weak or a couple of them were out.
Hooked up my AE and pulled codes, one of them was P0261 # 1 inj. Truck is fully warmed up and is running fine. Did a koer glow plug test and it came back ok. Power balance looks good now.
Probably looked different when I finally got it started this morning. Took 3 cranks to get her going and it sounded like crap till it got a bit warmer.

Don't drive the truck but once a week but since its gotten colder here than usual is been harder to start when cold. Of-course I go thru the glow plug wait and then it kinda stumbles when its about to start. I do it again and most of the time is starts but seems rough for a few seconds. Once the truck is warm, no more problems starting.
I'm wondering if I have a glow plug gone bad and that cylinder is not warming up for me. Today I plugged in the block heater for maybe 2 hours and it started first time. Also, if just leave the block heater plugged in for long periods of time.. would it get to hot?? and wonder how expensive that is, most heater are costly to run. I have a timer but just wondering.

Truck has performed flawlessly during that time period. Early build 2003 CC SB 4wd King Ranch truck 94,000 miles I purchased new in 2003. Good batteries. Bone stock except for superchips tune.
First sign of trouble: Two weeks ago CEL came on, P2285 Injector Control Pressure Circuit Low, as soon as truck was started after sitting unused for about a month. Bought new sensor, haven't installed it yet (early model sensor located under turbo on rear of engine and a real pain to change). Truck still started fine and ran fine. Dreading the ICP sensor install, I continued to drive the truck. Drove truck 5 miles to get tractor fuel. Got fuel, started truck and drove away. Got 200ft and truck died. I changed secondary filter under hood, turned key on and let pump cycle about 4 times. Truck started. Cleared codes. No longer have CEL. Drove 5 miles home, shut truck off and no start.
Troubleshooting: Changed primary filter under truck. Really cruddy (probably 80,000 mi on it). I cleaned inside filter housing thoroughly. I had to cycle pump KOEO about 6 times before it started. Shut off and immediately tried to start. No start. Ran pump KOEO about 30 seconds. Started. Shut off and same result. I then drove truck 4 miles driving both normal and WOT. No problems, no smoke, no CEL, ran perfectly normal. Shut off, no start until cycling pump KOEO for about 30 seconds. No codes set.
I then removed cap from secondary filter and checked for trash. Fuel and bowl were clean. I did notice fuel drained completely from bowl in about 5 minutes. I reinstalled filter and put pressure gauge on housing.
Fuel pressure readings: KOEO 55psi after about 3 seconds. Engine running 55psi. Turn key off and pressure instantly drops to 25psi, then bleeds off to zero over about a 3 minute time period. Does this seem normal?
Questions: Could the clogged fuel filters cause the p2285 code to set? Could the HPOP system have developed a leak and cause these symptoms?
Could an injector leak cause these symptoms and engine still run ok?
Action Plan: Install new ICP sensor. Do bubble test to check for injector compression leak. Install Blue Spring mod. Waiting on parts. Possibly buy scanner which will read HPOP output etc. Any recommendations here?

I just bought an early 04 (01/04) and it starts hard when it's cold. It starts just fine when it's warm. It idles a little rough it seems and it's putting out white smoke, but not too thick. There are no codes on the truck.
I performed the "bubble test" and got no bubbles at all. I have found that it is common for oil rail o rings and dummy plugs go bad and I'm being told that is what the problem is.
Could the oil rail seals be the problem? It makes sense to me only because there are no codes and I feel anything else would have thrown a code.

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.

I have had my truck for about 4 years bought it used. I've replaced the motor due to #1 cylinder blowing up. So after I replaced the motor, it wouldn't start. Replaced O rings on HPOP (High Pressure Oil Pump) and started. When moving back to Colorado where I am stationed. It started getting harder and harder to start.
Then it got to the point where it wouldn't start so I would have to wait until I could start it or use a shot of starting fluid and yes I hate that. But I don't have a choice. I've bought new O rings replaced them and my IPR with upgraded screen. It fixed it for a week then the hard start came back. Tried unplugging ICP Sensor still hard start problem. ICP was reading 85%. When the truck is cold it fires right up no problems till it gets hot! Then driving down the high and hitting an off ramp it will shut off. When I try revers it will also shut off. The truck only has 111,252 miles.

Earlier this week the truck was hard starting every time. Tested the batteries: 12v engine off, 14v engine running, all good.
The next day it threw a P0284 – Cylinder #8 contribution/balance, and was clearly missing on a cylinder. Despite the lack of a puff of smoke at start-up, I was pretty sure it was an injector. So I ordered one from White Bear Lake, and a fuel pressure test adapter from Strictly Diesel. Then I decided to do some testing with AutoEnginuity. Tried the injector buzz test first and got a note that the truck was not capable of performing the test. Tried starting truck and gauges swept and wouldn’t turn over. Tested batteries again: main battery 11volts, aux 12volts.
I got the batteries in and the stupid thing runs like new. Only codes are P1000 and P0603. Truck passed the injector buzz test, and cylinder contribution test graph is almost a flat line.
Take-aways:
1. Bad batteries can cause all sorts of havoc.
2. Always use a voltmeter that displays tenths of a volt, because if it’s only showing whole volts, it could be rounding up. The 12 volts from my first test was probably more like 11.6 volts.
3. Always do as much testing as possible before buying parts.
4. Costco does not sell Kirkland batteries anymore. They only stock Interstate, and the Interstate warranty has dropped from 36 months free replacement to 30 months.
5. The Walmart and Autozone batteries with the five year free replacement are “out of stock” and I’m guessing they won’t be back with Interstate dropping their replacement dates.
6. Most of the car batteries in the US are made by Johnson Controls.
7. Motorcraft batteries did not get very good reviews.
8. Interstate said that AGM (absorbed glass mat) batteries stand-up better to the additional vibration and heat experienced under the hood of a diesel, but they are significantly more expensive, and not all the brands offer an AGM with a better warranty than their best lead-acid offering. Also, the guy at Sears said AGMs are only beneficial for newer cars that continue performing electronic functions after the ignition is turned off. He said he’s seen lead-acid batteries outlast AGMs, but didn’t specify if those were out of diesels or not.
Questions:
1. Can I expect the P0603 to go away after the drive cycle is complete?
2. What should I do with the new injector? If I return it there’s probably a restocking fee. If I wait for a complete injector failure I don’t get the core charge back until then. With the FICM compensation, I don’t know of any way to identify weak injectors without IDS.

My '03 6.0 is hard to start and runs rough when cold. Not just cold outside temps, but engine not up to temp. Starts and runs like a champ once it's up to temp. It was doing this when I got it, but it's getting worse.
From what I've read the common culprits are:
1 - failed solder joints on FICM power supply board
2 - bad power supply side of the FICM
3 - updated flash needed for FICM
4 - injector stiction
5 - leaky O-rings at high pressure oil rail to injectors
I have read up on how to run the voltage test on the FICM with a multimeter.
Seems like I would have to go to a dealer to have the software version for the FICM checked.
I am 100% competent to do the tests and/or repairs myself, but since I recently moved in with my fiance in a condo and my tools are in storage, I will have to do it at a friend's house. That being the case, I want to know what all of the common things are that I may need to check for so I am prepared. So, I wanted to see if there were any other common causes of this issue.
I plan to test the FICM voltage and give FICMRepair.com some business if that's the problem. And if that's not the problem (or maybe even if it is) I will get the injector seal kits and replace all of the injector seals as well as disassembling and cleaning the spool valves in the solenoids. I will also change oil and fuel filters with Motorcraft parts and Rotella synthetic oil while I'm in there.
