Ford 6.0L Power Stroke Diesel :: 2005 F250 Stalling At High RPMs
Jan 14, 2017
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'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

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 2012 F-250 6.7L w/8K miles. I have been struggling with this issue for 6 mo. The engine feels like its missing at low RPM. I would equate it to the feeling of a bad coil pack in a gas engine. The boost indicator drops to 0 for a split second then recovers. The dealer says they can't find the issue but went ahead and replaced the turbo. After the turbo replacement It got worse. This is an intermittent problem with no codes.

I have 2003 f250 6.0, had the turbo rebuilt and I put it back in, my turbo is whistling but I'm also getting a humming noise kinda sounds like a when u down shift at high rpm's idk what's going on, I try and power break as well to build up boost and the tires do not even spin...

6.0L revving to extreme high RPMs and kill? Blow turbo was replace, fired right up but upon pulling it out while giving it lower RPMS (2000) engine over revved and killed - Now crank but no start. Checked everything. Removed valve covers, checked injectors, great fuel pressure.

So I just purchased my first diesel a couple weeks ago (2003 f250 Lariat). I love it! However, I'm having concerns about my turbo whistle on it. At idle and while in higher RPMs is sounds ridiculously loud (even at 0 PSI in the boost). I've been doing my research on it and I know the 03's have the loudest sounding turbos because they have less vanes than the later models. I know without a video it's going to be hard to diagnose, but I am wondering if a loose boot would cause a turbo whining sound through the exhaust? I have yet to hear ANY other diesel in person that has a turbo whine as loud as mine.

I've been having rather slow throttle response with my 6.0 f250 diesel at lower RPMs. Obviously, this is to be expected to some point.. Whether I'm cruising on the highway or through the neighborhood, if the truck is at lower RPMs and I try to accelerate, it doesn't want to. In order to get it to accelerate, I have to press the gas down enough to downshift it then it'll take off.
The truck doesn't have a loss of power at higher RPMs, it takes off like a bat out of hell. I've put 175CC injectors in, tuned it, power max turbo, EGR deleted / studded, etc. It's almost go out with acceleration, or go turtle power with acceleration.
Oil pump was replaced a couple years ago. This problem existed through it all, and it's rather annoying. The truck doesn't want to produce any low end power. If I try to hit the gas enough to accelerate but not enough to force a downshift, I'll just blow smoke, spool the turbo, and barely accelerate until I down shift or push the truck through it. Turbo PSI is roughly ~15ish-20ish during the sluggish transition.

After start up it bucks and surges, acts like it is starving. RPMs fluctuate. Once it fully warms up and driven a little bit it clears and runs normal. This all began after the alternator went bad and battery warning light came on. Batteries never went completely dead, but could low batteries effect sensors or control module. This morning it was difficult to start, not low battery problem, but a lot of bucking and black smoke. I changed the fuel filters and a little better. New air filter last week when alternator was replaced. No codes have appeared.

I have a 2005 Ford f250 Diesel 4x4 with - unfortunately - the crappy 6.0 engine. Yesterday my Daughter parked in the yard and this morning the truck not only will not start but will not even turn over. I thought maybe the batteries were dead but that is not he case. When you turn the switch on you can hear the pump start up but it will not turn over? All the lights come on and the bell comes on when you open the door and the dashboard lights work but the thing will just not turn over. I am assuming this may be some type of electrical issue or something but whatever the problem is it just came out of the blue. Ford imo should have recalled this engine.

I have an 05 f250 with 109k. Recently I turned off my truck, waited about 45 min or so and upon returning the truck would just crank and crank with no fire. After waiting about 4hrs the truck started right up like nothing was wrong.
Yesterday it did it to me again. This time I have it a small shot of starting fluid and it fired right up and ran like a champ all the way to the shop..... I got the call today from the mechanic saying I have 5 injectors that are bad, 2 glow plugs and harnesses. His quote was 2400 out the door.

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 problem with my Ford F250 6.0 Diesel. The truck got a new HPOP but still wont start. ICP show everything between 15 und 75 PSI, it raises to 75 PSI max during cranking. The IPR shows 84,75% during cranking.
We get the code P0270 and P2285 in exchange but never together. We already checked the FICM but it looks good on the inside. I now ordered a new ICP sensor....

I have a 2005 F250 6.0l. I have no speedo and the ABS light is on. It was intermittent at first. It would go on and off if I hit a bump or braked quickly, but now for the last month the light has been on constantly.
I have tried the following to no avail:
1. check the harness to the VSS (rear ABS senor on the pumpkin)
2. replaced the VSS on the rear
3. check the lines from the vss for resistance and open short (and short to ground)
4. checked the HS-can network (pins 14 and 6 in the DLC to the respective HS-can + and - on the module) both have less than 5 ohms (about 3 ohms found) and no short.
5. checked the resistance of the network itself across pin 4-16 and found 60 ohms.
6. ran scans with OBD fusion for ABS (no abs found)
7. ran scans with forscan with laptop, does not detect ABS unit neither new or old module. note the TBC and IC both throw codes about not detecting the ABS.
8. check HS-can on the PCM as well as VSS wire from abs to pcm, no shorts or resistance.
9. check the number 11 fuse, (good) checked ALL fuses, only bad fuse found was trailer light number 20 engine bay. issue was a wire at the tailer connector was t-taped and not sealed leading to a short to frame.
10. checked the connector to the ABS module for power on both constant power pins, for open ground on both grounds, and power on run, all with in spec.
I've been diagnosing this for the last week, I am running out of things I can think of to check.

This is my first winter with my 05 F250 that has the 4wd controls on the floor. I'm just trying to figure out the proper way to put in in and out of 4wd. I did some reading and everyone talks about engaging the hubs, but my truck seems to have automatic hubs because the selector Is not on the outside of the hubs. Am I missing something obvious or am I just reading the wrong things. When I bought it at the end of summer, we tried 4wd out but only for a second and it would grind and be generally unhappy when we were doing it (while driving slow, and complete stop to go to low).

2005 F250 4X4 6.0 .. Why my truck just stopped going when put in gear and the TOW/HAUL light just kept coming on, without pushing it 2 days prior? Now it will not go anywhere, starts great, gas pedal works because RPM's go up when pushing! Just will not go when put in drive or reverse! What else I can do? I replaced cylinoid B in the transmission, speed sensor, and brake switch.

My 6.0 has been leaking oil for a couple weeks now, possibly longer judging by the staining underneath. Very slow leak. 1 drop hits the ground when I get off work and go to get in the next morning. It never really reads off the dipstick a drop in the level. I had to top up the oil yesterday but that is from about a 2-week span. But I want to get it fixed. I've attached pictures of where it's coming from and was hoping to get pointed in the right direction. Also its a 05 f250 and coming from the driver side.

This has happened twice now, both times immediately after towing. I'll start it, begin to accelerate, and it will just putter out. It'll start right back up but it'll putter out again. After 20-30 minutes it'll start (and run). I have an edge programmer and it doesn't turn on when this happens. I get a turbo warning on it that the psi is at like 43/46 even though I'm essentially at idle so it seems to be getting a faulty error thinking the turbo is under too much load.

My 05 F250 CC 4x4 had a problem where it was wondering to the right.
I had the front end checked out and they said everything was good and within spec but they discovered a bad tire (internal belt separation).
Had two new front tires installed/balanced and the problem seemed to go away for a few months.
Now the problem is back even with the new tires. Could the steering box cause this or is there something else I should be looking at?

On my 2005 F350 Super duty 6.0 Power Stroke Diesel I have extremely high oil temps when towing and also have a warm start problem. I need to tackle both these problems at the same time but I am struggling to find the correct (and still affordable) parts for this. My local parts store and Ford dealer are way over priced.
First, I need an oil cooler (truck has an EGR delete so no EGR cooler).
Second, I want to replace all the seals in the high pressure oil system and replace the HPOP elbow.(Already replaced IPR)
Third, I would like to do the Blue Spring update as well while I am in there.
Looking for part numbers or kits numbers. I usually do all my own research but right now I am way too swamped at work and home to find these parts.

2005 Ford F250 6.0 Diesel (bought new). Never had a problem with the engine until about a month ago. Engine has 220,000 miles on it. Oil and filters changed regularly. Ran low (not out) of fuel, started sputtering badly but not killing. Filled up with diesel. Ran better, managed to get home. The next day it was dead. Crank but no start. Since then I have done the following (not in order):
- Changed EGR
- Changed ICP
- Changed IPR
- Changed the STC fitting
- Changed all seals in the HPOP
- Changed glow plugs and harnesses
- Tested each fuse and relay
- Installed new batteries
- FICM tested 48V
- Changed motor oil and filter
- Changed both fuel filters
- Checked for water in the fuel
- Purged air from fuel line
- Replaced dummy plugs
- No codes
- Prayed the rosary
One month later, still crank no start. Thinking about using it as target practice with the AR-15.
