Ford 6.7L Power Stroke Diesel :: Randomly Cuts Out When Accelerating
Jun 30, 2016
I have a 2013 that randomly stutters or cuts out for a second while accelerating. This happens whether I am slowly accelerating or full throttle. This used to happen once every few months but it is happening more frequently now. It will randomly happen while trying to accelerate on the freeway. The truck feels like it stalls, then takes off. It feels like it loses boost pressure so maybe a wastegate issue or possibly an EGR valve issue. No codes are set.

The engine in my truck sometimes cuts out seems to be at idle. Takes a lot of cranking together going. Might be related but the electric fuel pump seems to run every time I turn the key on and if i sit with key off and the engine not going. I hear the pump come on again. No external leaks can be seen.

I have a 2004 F250 4x4 with 204,000. runs great! But last year, I noticed the A/C would work fine to begin with, but after running down the road a bit, it would cut off and I would have to turn it off, let it "rest" a bit, then it may or may not come back on, now I am a electrician by trade, and I figure it is a bad switch somewhere, but a intermittent problem is heck to find sometimes!!!
I replaced the low pressure switch in the accumulator, then I was thinking the little wiring plug might be bad, so I replaced that but it's still doing it. I was going for the relay next, but I'm not sure which one it is and can't seem to find a wiring diagram for the system. I'm stumped on which way to go. Its full of 134a and will freeze you out--- when it works!!

I have a plow truck that over heats and cuts off. And when it cuts off it won't start till next day? I know the plow has to be low this is not my first plow truck.

Where the factory BT module is located? The other day while listening to music, I hit a bump and my bluetooth cut out, then came back about 5 minutes later. Almost as if it lost connection to the stereo then reconnected....wondering if something isn't connected securely...

Lately (within the last year) after about an hour in the truck my radio will make an electrical pop sounding noise and then the sound cuts out for about one second. The pop is not very loud. It will do this about every 15 seconds at first and then after ten or so minutes it's every 1-3 minutes. Doesn't matter the source, it does it on all of them. The volume is at normal (adult ) listening volumes. Interestingly the subwoofer does NOT cut out which points me towards the amp inside the radio. It also seems as if heat may be part of the issue as it takes a while before it happens. If I turn the radio off and wait 15 minutes and then turn it back on it will work for a few minutes and then start popping.

Just installed my SCT livewire TS. The truck runs good without a tune but it has egr delete so it had check engine light. So I put a performance tune with egr disabled so it cleared code. But I noticed at pretty heavy acceleration the fuel seems to cut out. Usually once boost builds. Does the same with the street tune.

This truck isn't mine but it's an 05 F250 automatic. We just did oil cooler, STC, standpipes, dummy plugs, EGR delete, and cleaned the turbo. Truck starts perfectly and runs great 99% of the time. But after a high load throttle situation right when you let off the throttle the engine sounds and feels like it cuts out for a split second, then it comes back and everything is fine. It does it with stock tunes but it is more noticeable with his SCT tunes loaded. There are no codes being set. The weird thing is if your drive it relatively easily it never does it, and it never does it while it is actually under high load, at WOT it pulls like crazy until you let off a bit and then it happens.. It also doesn't do it every time but it is fairly often. It has edge insight with fuel pressure monitoring added, ICP doesn't drop out and neither does fuel pressure. What could cause it to do that?

2003 6.0. Really, really hard or no start in winter. Started it up today and it misses until warmed up. That sounds like injectors.
The next issue is it stalls randomly they say. I tested FICM with a volt meter and it's constantly just a hair above 48 volts. Key on, cranking, running, doesn't matter. It's a 7 screw FICM in an 03 so I'm guessing it's been replaced. It also has 3 zip ties around the back half of the FICM. I'm not sure if it's holding the FICM in place, or holding a connector on the back.
Today after testing the FICM and starting it, and getting it warmed up, we let it idle around 30 minutes. It stalled like the key was shut off. When this happened, it would not restart for about 1 hour. It would crank and spin over fine, but you could tell it was just the engine spinning over and the injectors were not trying to fire. When it finally did start an hour later, it took some cranking and you could hear it trying to fire like the HPOP was empty and building up pressure before it lit off.
No CEL and oil pressure gauge on dash moved up to the middle while cranking. I'll put the scanner on it next time I'm there and watch live data during the no start condition. What all to monitor while cranking or where to look in case this isn't an unheard of 6.0 issue.

While i am pulling a loaded trailer we have been experiencing a random Chug that only last about 1 second we have no lose of power during when it happens. We Recently just replaced all fuel Filters. We have an updated EGR on it with a cold air intake and muffler delete. It has about 180000 miles on it it runs awesome and starts right up just trying to figure what this problem could be..

I have a 2004 f350 with a 03 bullet proofed motor. The truck did not have any power and the turbo wouldn't support until I put a new vgt solenoid in and it ran great for about 3 miles... Stalled doing 65 kinda lacked power while accelerating but got up to speed quick. I pulled over and no start. It is running error code kam on pcm from disconnecting batteries but could this cause the stall and no start? Or should I be looking into icp sensor?

It's a 2006 Ford F250 6.0 diesel with 307,000 miles on it. Up until a week ago it ran great but when I was in a drive thru I turned it off (to order) then turned it back on to pull up but the idle was very rough and the truck shook as I revved it up but it went back to normal after I saw a puff of white smoke. Ever since then every few stop lights I will begin to accelerate but there isn't any power and it shoots out a lot and I mean a lot of black smoke for a second then the turbo spools and it's normal.
Today though I turned a corner and began to accelerate after but I had no power at all it shot out an un manageable amount of black smoke mixed with very little white as I pressed the pedal. I put the pedal to the floor and the rpm were up to 2000 still no power I out it in tow hail still pedal to floor and now power! At this point I pulled over and called my dad figuring the truck wouldn't move anymore but I got no answer so I tried to go again seeing how ideas almost and and the truck worked fine small amount of lag but it ran made boost and worked until I got home. What could it be? I've heard maybe my turbo is bad maybe my egr valve but I'm just not sure.

In my 2007 f-250 it started with the door ajar chime that would click on then off somewhat randomly. Then it started doing it every morning on a cold start for about 20 minutes then the light and chime would click off. Now it stays on constantly. And my automatic headlights are turning on when the engine and ignition is all off and killing my battery. Where to start?

04 with 170k miles. truck runs fine. every now and then truck shuts off while driving. turn it off the it restarts every time. Only code that comes up is number 6 injector. The contribution test injector is firing right. FICM voltage is 47.5. has new ipr and hpop also 6k miles ago. Could it be number 6 shorts out or something crazy killing truck? or maybe a crank sensor.

I have a 2004 6.0 that has been pissing me off to no end lately. I has a random dying/no start problem. If it idles for ten minutes, it'll die sometimes. And if I drive it and shut it off, it won't restart sometimes. I just drove it three hours on Friday, shut it off and it restarted immediately. Drove it around town all weekend and it started fine every time.
Now driving it home and stopped for fuel 45 minutes in, and it won't start. I have all sensor readings in spec except for I have no ficm sync while cranking. I have about 5k miles on new hpop, injectors, ipr valve, icp sensor, oil rail rebuilds, stand pipes, ficm and engine harness and injector harness. No codes either. If it sits for a couple hours it'll start fine. I've wiggled as many wires as I can and it still won't start. I have rpm while cranking on my edge too. Don't know if that would rule out crank sensor or cam sensor.

Back again.. I just replaced the HPOP and IPR valve on my truck a few weeks ago. While the turbo was out I cleaned it and applied a small amount of anti seize on the unison ring. When installing the turbo I had moved the y-pipe a little to get the turbo in place. About a week after it was running again I started to get a squealing noise under acceleration. The noise isn't a whistle like the turbo but an actual squeal. Its a little bit louder than the turbo whistle. If I am in park and rev the engine it doesn't happen. It only happens when I accelerate and seems to be when there is boost. If I let off the gas pedal the noise stops. I don't have an issue with making boost. I did replace the turbo boot when it was apart a few weeks ago so I don't think that is the problem I checked the y-pipe clamp and down-pipe clamp and both are fine. I replaced the serpentine belt this past weekend and checked all pulleys, they were all very good with no play. Another thing, the pitch of the noise seems to change with rpm's too. What could be causing this type of noise?

What could be causing my turbo to be fluctuating while accelerating? I can definitely hear the difference in the sound of the air and today while towing my camper I could even see the dash gauge bouncing around some.

A Little Background, my FICM wasn't bad per se but it would dip below 45 volts when the outside temp was around freezing. I pulled it and sent it for repair at the same time the Atlas 40 tune was loaded into the FICM.
First few days of driving mileage was better, truck ran great. All of a sudden one day pulling into the driveway it randomly shutoff. Two occasions since it has acted goofy at started, bucking a little a low throttle. Mileage has returned to how it was before I had the FICM fixed and ATLAS tune applied. To this point I had no codes at all.
Now today it randomly throws P0341 - Camshaft sensor out of range.
So heres the question - do I replace the sensor or try to get at the harness for inspection? Out of range would usually mean the sensor itself is failing while open circuit is usually wiring related. I know its uncommon for this particular sensor to fail but i'm not sure which direction to go.

I think my starter took a s hit like I said truck randomly doesn't crank all lights on dash come on can hear injectors buzzing turn key nothing. Took wire off passenger's side of truck yellow wire touched to pos post solenoid click no crank. So I had the old lady sit in the drivers seat well I hit the starter with my BMFH started right up could something else cause this or should I just bite the bullet and replace the starter?

So This all started when I noticed my 03 Ex 6.0 started to not upshift every once and awhile.It has 300,000 miles on it.As far as I know it has never had tranny filter changed.So I said it shall be done.I did both internal and external filters and the fluid was very dark but not burnt.The pan was very clean and no sludge or metal on magnet.Put in new fluid and ran the truck until warm and checked fluid level and all was good.Now this where things get weird.Went for a drive and truck would not up from first easily or I had to feather pedal to upshift. If I put my foot into it I got a lot of black smoke after about 5 seconds and some sort of shuttering in the engine on deceleration. Ran AE for codes and nothing came up. The engine has EGR Delete. Blue spring, new injectors, glow plugs......
