Ford 6.0L Power Stroke Diesel :: 2003 F350 Truck Revving Up Out Of No Where
Aug 24, 2017
So I'm having a problem with my truck revving up out of no where. Happens more when I'm driving. It only shoots up a little bit but sometimes goes up 1000 more rmps. Happens for a quick second then stops and does it again. I've had the ckp replaced and it has an egr delete. Other than that it's stock. I got home and let it idle for a minute. The rpms fluttered up and down in small increments and almost stalled out. What is causing this?

The other day, I started having problems with the truck not starting when at operating temp. Went for a drive and stopped a a scenic overlook, and spent about 30 minutes taking pictures. Went back to the truck, and it wouldn't start. Outside temp was about 95 degrees.
I tried for about half an hour to start it, but all it would do is turn over. There was a work crew there with their heavy machinery, and I was able to borrow their starting fluid. One quick squirt into the intake, and it fired right up.
Although I do have an oil leak from the right valve cover, when I checked the oil, it was just off the full mark. The truck was parked on a slight angle with the driver side being about a foot higher than the passenger side.

I am getting ready to go on vacation this weekend with my f350 and I was driving today when suddenly the truck shut down while going at about 25 mph. I tried to start it and it just kept cranking. I got it started 5 mins later and it threw a P0069 code. I drove for about 2 more miles and it shut down again, and started right back up. I'm guessing map sensor? This was the last thing I needed to happen!

A little background, this is an 04, f-350. It sis not start a week ago so I charged the batteries and it started, started fine this morning, (had not driven it for the week) Drove it to work, 35 miles, parked it, and it will not start.
I downloaded Torque and got a few numbers,
HPOP 1900 FMP 48V (repaired last summer) and FVP 11.5V.
Ran out of battery to surf more and look, so I am trying to figure out the app, and the issue with the truck. It seems to turn over good, until I ran the battery down, and the GP cycles normally, and the injector buzz seems good. Temp is in the 50's...

I've got a problem with an '05 f-350 with the 6.0. Initially I had a code for the #1 glow plug so I replaced the plug and the code was still there. Next I tested the harness and the rest of the plugs on the same harness and everything checked out fine. This lead me to the Gpcm which I then replaced. The first thing I noticed was when removing the old Gpcm I got a spark when removing the mounting nuts.
When I installed the new Gpcm the truck started fine and no codes came up so I thought all was good till I went to start the truck the next day and the batteries were dead. I thought I possibly left something on so i started charging the batteries but noticed they seemed to have a draw on them. I put my hand on the new Gpcm and it was very warm with the key off so I have the batteries disconnected till I can figure this out.

I have a 2004 Ford F350 6.0. It is leaking diesel from the front of the engine to the ground. I have a video of this and pictures as well but I'm not sure what I'm looking at. What I can do??Puddle after about 20 min of running.
Dripping from here, left of hose....

I have a 2004 F350 with 6.0. My problem is the 4x4 will not engage from inside the truck. I have to get out and twist each hub to lock in the 4 wheel drive. If I rev the engine with high rpms the front will lock in with a big jerk. It use to lock in just by turning switch. What is the best way to fix it?

2004 f350 after i shut the truck off something was buzzing. So I popped the hood and found its the injector harness or injectors.Is this normal or something I need to look into?

04 f350 drw 2x4 ... I know this is a weird question, but i put 4 new tires on the rear of my truck and developed what i can describe as "loose body" symptoms. Most noticeable in going down the highway it feels like the rear of the truck sways and its hard to control and keep straight at times. Check tire pressures n front and rear suspension for broken springs or loose joints. Nothing looks broken or out of place. Prior to replacement truck drove straight n all was good. Also noticed steering wheel is now off center.

What the problem is with my F-350 6.0. I have an intermittent problem with my Speedo reading zero while I'm doing 70mph on the fwy. since the speedo won't work the truck goes into limp mode, the turbo will not function at optimum level. I have replaced the diff. sensor, the trani sensor, the a.b.s.sensors, the instrument cluster to a reman cluster. Then when I had a local mechanic plug a laptop dianostic program on it as he was running through the system inadvertently the radio cut out, so I found that who ever installed the after market stereo they cut a few wires to the harness, I went to the junk yard found the harness end and replaced the end. so with all that said and done no one knows what is causing this speedo not to work and limp mode. about 4 years ago the oil pump stopped working and ruined the turbo so the whole front end of that glorious 6.0 was rebuilt the problem started about a year after that.

While driving the other day, the truck suddenly began to stall when pressing the accelerator. The water in fuel light came on as did the glow plug light. This continued with the truck sometimes dying all the way and other times just stalling then picking back up. No difference in throttle pressure seemed to make a difference except that letting off totally then slowly pressing seemed to let it keep running sometimes.
So I get home and drain the fuel water separator. I gets about a thimble full of water and lots of the rusty looking junk others have talked about. Try to run the truck again, same thing as before. I then changed fuel filters and thought that had it licked but after about 10 minutes it started again. By the way, the 6mm plug seemed to have about a third of the threads rusted off. Not sure what that means as I drain it at least twice a year.
I have read a lot about the ICP and IPR issues and was wondering if this could be my problem. I am hoping its not the HPOP. My other thought was something in the fuel tank blocking the in tank filter. I checked the top mount bowl and it was only about two thirds full after running the truck

I have a 2016 F350 Powerstroke fully deleted for about 3k miles. Truck was running perfectly then out of no where started running like crap and had very minimal power 500-2000rpm. Once 2000rpm hit, turbo spooled up and made power. Very odd. I cleaned out back pressure sensor, map sensor and hoses. No fix. Did a hard reset and the truck ran fine again and had low end power.
Ever since then I started hearing very odd fluttering sounds coming from what I think is the turbo. Also noticed my OEM boost gauge doesn't work. No reading from it.
The flutter only comes on when the truck goes under load for a short period of time and then I let off the throttle. It seems to running fine other then that and maybe a little bit more sluggish then normal. Any things I can check before I put it back to stock and bring it to the dealer?
MODS:
NO Limit EGR Delete
Flo-Pro 5" Straight
S&B Intake
SCT Livewire w/ custom tunes
Also, I had a lot of problems with my live wire software. I have to send it back to SCT to get warranty problems fixed which I'll be sending out Monday. They think my tuner is stuck in demo mode for some off reason.

So my 11' F350 is over heating when the engine RPM's are below about 1300 whether the truck is moving or not. If I let it idle for 2-5 minutes I can watch the temp gauge go to red and an engine over temp message appears. I noticed that if I rev the engine to > 1300 RPM it cools back down.
This appears to be a water pump going bad, any other thoughts? Are there instructions for changing the water pump here on the forum?

While headed back to town my 2000 f350 7.3 with 444,650 miles (I'm original owner) and have performed maintenance and repairs since mile 3. Truck started to loose power and eventually stalled, was able to restart several times to limp home 7 miles in one hell of a snow storm. Very confused, replaced cam position sensor ( keep one in jockey box ) replaced fuel filter truck starts then stalls out. Don't know if a bad HPOP would allow start up at all. Fuel pump???

I have a 2001 F350, 7.3. My service engine light came on and immediately the truck started to run rough and lose some power. I've checked the under the cover connections and they were both connected, I replaced the cam position sensor and I still have the same problem. The worse part of the hold thing is that there are no codes stored so I'm flying bind. Where to go next.

I bought a 99 f350 truck. it has a van turbo and exhaust back pressure delete. The truck wont make more than 3 PSI of boost. Ive got a p1690 wastegate actuator circuit code. unplugging the waste actuator does nothing. With the van turbo, is the actuator required? Is this code stopping the ecu from fueling and creating boost? I did a cylinder balance test, and cylinder 8 failed. Is a single injector not quite balanced enough to make it not boost past 3 psi? The turbo appears brand new (previous owner said it was), charge pipes hold pressure (tested), EBP Sensor tube is clean (shows up to 24 psi). I tested the wastegate actuator, OnDemand5 says if its over 50 ohms, its bad and replace it. its 69.5 ohms. Again, i dont want to replace it if i dont have to, as its not being used (no wastegate on van turbo), but if the ecu is preventing it from spooling because of the solenoid, ill change it.

I have a 2002 f350 7.3. It was running fine 2 days ago. After I put some diesel in it my water in fuel light came on. I drained the water out and took all the fuel out and put fresh diesel in it. It starts up fine and idles okay but when I try to drive it it looses all power and acts like it's starving for fuel and almost dies. It was smoking white smoke for a little bit even after I took all the water out but now it's black. What it could be.

Am looking into buying a new transfer case (TC), and one web-site indicated there were 2 different automatic transmissions; Manual vs electronic -shift? So some TC's for 2000 AT's would not work? I found one (used) that was from a 2002.
My truck came to a grinding halt yesterday and I believe the TC. I had been hearing noise for a while and had been in the process of eliminating other causes (u-joints, ball joints) and think it was the TC all along.
I did not notice any issues with the AT prior.

I recently bought an 03 F350. I've noticed on cold starts that it has no power. After about 5 minutes it runs very well. I have not noticed any misfires or smoke and there are no codes thrown. Based on what I have read here, I assumed it was a FICM issue. I just got done testing it and it was at a solid 48v with 1 dip to 46 on engine crank. I'm baffled at this point. The truck literally has no other issues except low power for the first 5 minutes.

I noticed the aftermarket controller in my 03 F350 is not working. I am wondering where the fuse(s) might be located. Under the hood? Are they fuses or relays?

I have a early build 2003 f350 6.0. It will not start. Readings are good. ficm 48 to 48.5, synced, icp volts .30, icp climbs above 1200 psi, bat 13 to 13.5, ipr 14.8 to 40, fuel pressure 82 psi during crank..... will not start. Last week tore it down and replaced the tube of the hpop, found a leak in map hose and cleaned the turbo (vanes, ring). Ran ok for a week... shut it off and my sons baseball practice and will not start.... towed it back 2 days ago and nothing..... just cranks... I am at a loss. Another question would be where do i air test the hpo system on this truck.... ICP and IPR are in the back of the motor and hard to get to. I have read there is a way to do it under the valve covers.... not sure.
