Ford 6.0L Power Stroke Diesel :: No Power When Accelerate While Driving
Jan 23, 2016
So I have a no start on my 6.0. I was driving and went to accelerate and had no power, pulled off of the road and was idling rough, I checked for fuel leaks-none. I put it in drive and engine cut off and wouldn't start again, changed the ICP (threw a code) still nothing, FICM is good, ICP is 950 psi at cranking, IPR is only at 54%. I'm at a loss of what to do next besides looking at the IPR, and I do not have the equipment for a leak test.

Occasionally when I'm driving, I'll accelerate and get a brief loss of power, then it'll pick back up, followed by a puff of white/blue smoke. This usually happens when the oil is over 120*, but not quite to full operating temps. It doesn't happen every time either. Only 3 times in the past week. Otherwise, there is a very faint haze of white smoke that seems to be constant. It is very difficult to see unless against a dark background. Oil level is good, I check it once a week, no rising or lowering levels.
I pulled the EGR yesterday, all good, although a tad dirty. Cleaned up no problem. Haven't had a chance to do a bubble test yet. There are some DTCs, but I can't remember off the top of my head what they were. I'm about to go clean the inside of the truck, so I will pull those and update in a few minutes.
Truck has about 148,500 miles.
Torque Pro lists these codes: C1145, P0299, P0677

My f350 6.0 has seem to have lost its power, while I was driving home it would only accelerate at one constant speed, and driving up hill it would not accelerate at all, I also noticed an elevated exhaust temperature.. There are no warning lights or dash lights indicating any problem.....

I was driving and went to accelerate quickly and had no power, checked the boost gauge and it had very low boost. Continued like this the rest of the drive, all gauges normal, no check engine light, not towing or hot. Got home then next time out it was back to normal.
Someting to be concerned about? Or just a computer hiccup. Truck is '13 with 66k.

I have a 2004 F-250 with a 6.0 and am having a serious issue. The truck has about 240,000 miles and has been great until now. About a week ago the truck was running great and had plenty of power. I decided to wash it with my pressure washer (did not spray under the hood, however I did spray in the front wheel wells and underneath the truck). About 5 minutes after washing the truck, I took it out for a drive and noticed when I really got on the accelerator the truck would not want to try harder and motor got very quiet. Really all you could hear was the turbo whistling. Over this past week the problem has gradually gotten worse... a few days ago I had to feather the pedal in order to go up hills. If I gave it more than about 1/4 inch of accelerator, the motor once again would get quiet and the truck would start to slow down and would not want to work.
However, if I let up and only gave it a small amount of accelerator, the motor would sound normal again and it would pull up the hill. Today, I can do nothing more than idle back and forth in the driveway because the motor gets quiet and the turbo winds up if you give it even the slightest amount of accelerator. I have no idea if it's a coincidence that this happened after washing the truck, or if maybe there was a sensor that was rotted and about to die and I finished the job with the pressure washer. I already replaced the egr valve and have been running tons of Howes diesel conditioner and anti gel through it. The injectors were replaced about 50,000 miles ago so I'd hate to think it was them. The truck doesn't smoke at all either.

I have a 2005 6.0. I just got done doing the HPOP seals, injector o-rings, stand pipes and dummy plugs. I have drove the truck 600 miles since the work with no problems other than a wiring issue I got fixed...
I was driving at highway speeds, and all of a sudden I lost power and got a shake when trying to accelerate. I pulled over and turned it off, and when I went to restart it I got nothing at first, then it went to what seemed like a partial crank followed by a thud. So I'm thinking I just hydro locked it. I waited a few mins and tried again, and it started but had a few knocks for 15 seconds or so, then it ran rough with smoke pouring out of the exhaust (grey then turned kinda white).
I the only codes I have are for the egr which I've had unplugged for a long time, and a glow plug code, but when I started it back up, I had no codes. I'm baffled. I did notice I have oil on my oil filter housing at the cap, a little oil had slung on to my wire harness and my intake. I don't even know where to begin!

I have a 2006 F250 6.0 Amarillo Edition. 133,000 When I bought the truck it was a theft recovery vehicle where the turbo, injectors, FICM and wiring harness were stolen. The company I bought it from replaced the injectors, wiring harness-new, and a used FICM, and turbo. Also has EGR delete and SCT tuner with basic tunes. I believe the SCT was put on to mask another problem. No dealer would spend that kind of money to sell a truck unless something was wrong. The truck would accelerate some with the tuner but shift the tires so hard it would bark them. I removed the tuner and went back to stock program.
The truck will barely move and takes a long time to accelerate under a load. In park and neutral it is fine. A friend has a ford diagnostic program on his computer and says the readings were all good except EBP was a little high. Removed exhaust and air intake to verify no restrictions. Turbo sounded like the vanes might be sticking so I replaced the turbo and VGT solenoid. Now truck feels like its trying to make more boost but not transferring power to the engine. Have blown the silicone hose off twice now during testing. Checked the EBP sensor and tube and only thing I see is a little carbon buildup inside the sensor. What else to check. I'm new when it comes to diesels.

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.

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 have searched and the only thing close is bad sensor for water in fuel light but it does not say they lost power. When driving or leaving from a stopped position, if I put any extra load on engine by pressing on accelerator pedal fast the water in fuel light comes on and the glow plug light comes on and the truck loses all power. Not 12V power just engine power. I have to let off the pedal and the lights go out and I have power again. Until I press the pedal hard again and it does it again. I have drained the filters and replaced them and still the same.

I have an 07 6.0 with 400,000 miles. Has been a great truck with no major problems. Before I started the work I had 3 bad injectors, running rough and the oil/ coolant temp just outside of 15 degrees. So I tour her down and replaced head gaskets, installed arp studs,all new injectors,all new glow plugs and new oil cooler. Ran great for a couple days. Then when driving to work lost power on and off for a few miles then completely gone could only go 10 miles an hour. I checked codes and there was the under boost code witch has been on there for a while and I forget the other code but it was for the ipr valve so I replaced the valve and right after still the same but that code went away and the p0470 popped up. So I cleaned out the ep sensor tube and replaced the valve. After several miles she now runs great but now I'm getting a little puff of white smoke when I take off and not every time and mainly when I take off some what quick. All codes are gone expect the under boost. I have an egr delete already.

So I was driving down highway when I lost power. Engine was still running just had no power and would blow black smoke when I got on the accelerator. I pulled the EGR valve and noticed it had rocks stuck keeping the valve open. Cleaned it all up and put it back in. Went for test drive and seemed good again until few miles in same problem. Took it apart again and same thing.. rocks. I did this 3 times with same results...rocks getting stuck in my valve.

So I have a 06 f350 6.0 and this started to happen yesterday. I was driving and all my temp gauges were ok says the tuner, but I noticed when I accelerated and went above 8psi the noise got significantly louder and wouldn't go above 17psi so the cause of this sound is making lose pressure somewhere.
- I check the hot side of the inner cooler pipe and boots for cracks or tears(nothing)
- I checked the cold side and the plastic seems to be in good shape except where the flex part meets the inner cooler had some little cracks in it
- I check the Intake for cracks, didn't see any.
Noise is still there and the loss of power.....so I'm at a loss!
Cold side pipe where I taped it
Hot side boot to inner cooler no tears
No cracks in hot side pipe
Hot side on turbo
Cold side of the inner cooler

Ok here is the back story over the last couple months with this late build 04 6.0 with 230,xxx miles. I had problems with it losing oil pressure at idle, which lead me to replace the hpop. After that repair the truck still wouldn't run right so i had it taken to my local shop for some diagnostics. They fixed a few electrical issues and got it running, also telling my I had 2 injectors on the way out. Due to expenses I replaced only the 2 injectors in my driveway. A few days later the ipr screen got plugged and failed. Replaced that, and changed the oil, and it ran for a week.
Now for this weeks problems. Yesterday the truck lost all power and stalled out on my wife. She pulled the codes while I was at work and this is what was listed
P0404-60===
Code: P0404 - EGR valve position control performance or range fault
P0405-60===
Code: P0405 - EGR Sensor A Circuit Low
P1335-60===
Code: P1335 - EGR Position Sensor Minimum Stop Performance
P2290-60===
Code: P2290 - ICP Too Low
Using forscan she forced the IPR 80% open and the truck would start but as soon as you try to accelerate it stalls out. Today i got the truck to start the same way. While idling the IPR was at 44% and I had about 870 psi at the icp. As soon as i would throttle up the icp would drop to around 400.
The hpop i put in a couple months ago is covered under a 1 year warranty and that's what I am leaning towards because of the plugged ipr last week. I waned to see what the great minds hear thought as well.

Finally registered on this site after hearing good things from others who are currently on here. Been a 6.0 PSD owner since buying the truck since new in 2003-F250 CCSB. I have done regular maintenance on it and have had a good run until recently. Everything is stock on the motor and currently has 229 000 miles.
I will describe my current problem: I have borrowed my brother's tablet and have the following numbers from the Torque pro app. While trying to accelerate it now has a hesitation and seems to not have the power.
At idle: 630 psi HPOP, 24 % IPR, 47 volts FICM, ICP volts .1
Trying to accelerate on at highway speeds: 1230 psi HPOP, 83% IPR, 47 volts FICM, ICP volts 2.6
Also, sometimes when starting the truck it seems to rev extra high for a split second. My brother says I may have a high pressure leak on the system. What I should check first?

Ratchet buzz noise my truck makes. Is not present until motor warms up. Noise is not present as much at idle but when you accelerate upwards to 1800 RPMs it makes such an obnoxious buzzing noise its embarrassing. Noise seems to come from top center area of motor.....

I have a 07 6.0 powerstroke, I had 2 bad injectors so I replaced all of them with reman's. I had a problem with them coming loose. the first time this happened it hydrolocked the motor, number 8 cylinder. so I pulled all the injectors and replaced all the seals and washers and torqued them down a little more than spec like 27 lbs. it runs great and starts great even at 25 degrees but I noticed this morning that when starting it up after it sits (cold) it blows blueish smoke until late it warms up and I accelerate. is this normal? should I check fuel filters? oil in fuel?

Was driving back home from shopping tonight and my truck was making a lot of noise when I tried to accelerate. I noticed the boost gauge on the dash was stuck at 35psi but the MiniMaxx showed 0psi.
No engine light so I babied it home which was about 30mins driving and managed to accelerate slowly to avoid the engine rattling. I didn't want to shut it down and restart in case it wouldn't start again for some reason.
When I got home I idled until EGT was <300F like I normally do (it never went over 700F when I was driving home) and then restarted it. The gauges worked fine, MiniMax showed boost and the engine revved freely with no rattling noise. I haven't taken it out for a road test, I'll do that when it's daylight.
Bad sensor somewhere? I would think if the turbo had failed it wouldn't have been fine after a restart.

I have a late model 2004 F-350 6.0 powerstroke. 182K miles. Auto Transmission
What happened. Condensed version
Left house, drove out to highway, got on highway. Everything feels normal.
About 1 mile of going 70mph, I notice I can no longer accelerate. after 1/2 mile, I begin loosing speed, and engine will not rev past 1000 rpm. I eventually pull over (another mile), put in neutral and will not rev past 1000. put in drive and start to idle to highway exit. it gets about another .5 mile and begin going up a hill when it completely dies. Will not restart.
No prior issues with the truck. Full tank of fuel.
What I have tested so far. Ficm 48.5 volts cranking. Icp .225V KOEO, .875V Cranking. LPOP is registering pressure on the dash. No Fault codes.
I have gotten it to start twice now, one time it allowed me to rev to 750 rpm, where i used 4 low to make it onto a trailer. second time would not rev at all. idling at 250-300 rpm.
That same night as it died, I drained the transmission pan/ TP filter and filled with 8.5 Quarts of Mercon LV. This is the first time I have done this since purchasing @ 161K miles. Everything seemed normal, no leaks present.
Also my buddy showed me how to enter the dash test mode and we cycled through these. Not sure if this is relevant.
So, What do I test next? I don't think its HPOP issue since the ICP is reading .875 volts at crank. I did unplug the ICP and it still would not start. I don't think its the injector side of the ficm because they buzz as normal with koeo, but this is a possibility as I don't have equipment to test. Egr valve is clean for age of truck.
Would it be possible that the Mercon LV knocked crud loose in the transmission causing it to fail/seize? would siezed tranny cause the engine to behave in this manner?
Fuel bowl on top of the engine was full of fuel. I have not pressure tested it yet as I can hear the pump running during key on.
could i have a bad crank or cam sensor?
Multi-injector failure?
Bad Icp with HPO failure?

Driving down the road at 55, the truck just stalled out and won't restart. This has happened before but it always started back up right away. Put a scan tool on it last week and it's giving me an injector 1 low pressure, and egr.
I've read that running the truck at low voltage could fry the FICM and cause all sorts or problems. I just replaced the alternator this week because the batteries always drained while the truck was sitting.

I have 2013 F250. 65k miles. 4" skyjacker lift. DPF, ERG delete. SCT programmer w/wicked wheel put in the turbo, KN Air intake..35" Ntto grapplers. I have a double shock steering stabalizer(skyjacker).
My questions are....drives great up till 75mph, then I get shimmy. Doesn't feel like the steering wheel, but more in the truck. It never did it until I went from 34" tires to 35"...before the lift. Also I wanna go to a 37" tire? I have lots of HP and Tourque. Love the truck. But I drive mainly all road miles. A lot. So looking to make it all fit together better...
