Ford 6.0L Power Stroke Diesel :: 2004 F250 - Sudden Loss Of Power
Jul 31, 2014
I have a 2004 F250 6.0 DuperDuty with about 170,000 miles on it, so far no major break-downs, just a starter and a blinker relay, but now I have a problem.
When I start now, the truck starts fine and it sounds fine, but it has almost no power even if I floor the gas peddle, there is a delay of like 2-3 seconds and then responds slowly, like some tractor. Eventually it starts to move slowly, and after it warms up (after a few minutes), the gas peddle responds more normal.
Also - at about 45mpg, at lower RPMs about 1250, the engine starts to shake (weird), it doesn't do it at idle about 850 RPM, or when I get it up to about 1800RPM+, but at about that 1250 RPM it does do it, luckily I driver locally for a few miles.
What could this be ? What exactly happens when I press on the gas peddle, what systems are involved and in which order?

I've got a 2004 F250, 6.0, with 150k miles. I was pulling a motorcycle trailer uphill in the mountains when suddenly I couldn't go over 10 to 15 mph. All the gauges read good but it just couldn't get any power.
Got to the top and checked over everything. Didn't see any issues. Drove it home (200 miles) the next day. It drove okay on highway but it felt like the turbo wasn't coming on. Coolant was low and EGR was gunked up but only slightly wet. From what I read, it sounds like EGR cooler is failing but would that cause the turbo not to come on or feel like that loss of power? Reading another thread, I thought it might be the fuel pickup but I dropped the tank and the sending unit looked very good.
I'm ready to throw on a bulletproof egr cooler, oil cooler and rebuild the turbo if necessary but hate to get to the end and find out none of that worked.

Ok I have an early 2004 F250. Recently changed out the #8 injector and then had to replace the ICP Sensor. Was running great then while driving down the road just died all of a sudden. Would start right back up with no issues. Continue driving and I am getting intermittent power loss. Also noticed that when it would lose power suddenly the glow plug light would come on.
Codes are P0102, P0113, P0272, and P1000.
P0102 Mass or Volume flow circuit low input
P0113 Intake Temp circuit High input
These are just soft codes not setting a light off. MAF is plugged in and I will check wiring here later after work but could this be causing my intermittent issues?

My 2011 6.7 suddenly lost power, started making noise and then stalled out.
After finding out that there are zero 24 hour service companies available in the LA area, I was able to get it towed to the local Ford dealer.the next day they told me it had dropped the #5 cylinder and that they would have to tear into it to find out what happened.
While I realize that any thoughts on the situation would be primarily idle speculation, what would cause this to happen at only 125,000 miles.

While driving home the other night at highway speed my truck lost power. I just filled the tank about 15 miles before then and everything was running fine. No lights came on the dash before the truck died and now can't get it started. Bad fuel? Clogged filter?

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 am still failing to appropriately diagnose the problem(s) with my '03 Ford E-350 7.3L Powerstroke. This van has only 69,000 miles on it. A week or two back (just a few days back in work time) it suddenly went from running perfectly smooth, clean and wonderful to this:
- Zero power. Putting the van in gear and flooring the engine causes lots more smoke not nearly any rev of the engine and just a crawl forward.
- Lots of smoke out the back exhaust, whitish. I cannot discern wether it smells like diesel or oil (because I'm ignorant here), but the smell is very strong.
- After warming up and idling ~ 15 min I check under the coolant cap and see no signs of bubbling or disruption (from opening the cap in the coolant tank).
- After warming up there are no warning lights visible on the dash, and I don't have a computer to read codes (if there are any to read).
- I replaced the turbo up-pipes which had a visible leak previously. This did not hurt the symptoms, though no more visual leaks under the dog house.
- I thought maybe I put gasoline instead of diesel in the truck, not so.
- To do the above test I had to use the fuel pump to get gas out the tank to test. I hijacked the fuel pump output and turned the car on a few times to get gas out to a tank. The pump seemed to work just fine.
This was all very sudden which is perplexing, and, in use, the van was previously an ambulette and in my few miles with it (maybe 200-300 only) use was extremely light for such an engine/van, just driving around doing errands. I am not sure if this is relevant (no one has suggested so, yet) but before all this happened I uninstalled the rear HVAC that came with the van when I bought it. The AC lines were sealed under the hood. The coolant line was returned at the doghouse (you can see this at the beginning of the video).
At the moment the van has no power to go anywhere. I have not yet checked the CPS or IPC sensors, and understand this might be the next route in standard troubleshooting?

My friend is working on a 2004 6.0 F-250 and it has used 75% of the coolant in the overflow bottle in 5 days. Can't smell coolant either. The inside of the tailpipe is wet soot black and there are wet spots on the tube coming from the intercooler to the turbo at the turbo and the intercooler. He's thinking EGR cooler.

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've noticed a power loss on my 04 6.0 for about a week now. I've drove it everday since first noticing, it starts great even with freezing temps here MI. Using a sct x4 powerflash for monitoring i check for codes, none thrown. All gauged data shows nothing abnormal besides turbo boost, reading at .1 to .5 psi in park. Being new to the 6.0 i started with checking all connections to and from turbo, everythings snug. Than moved to the EBPV and tube, cleaned both, now the boost bounces between .3 and -.3 in park. While driving i'm starting to get intermittent boost loss completely, than boosts kicks in and drives normal. Which leads me to my question, am i expierencing sticky vanes? Or could the vgt solenoid be doing this.

I just bought a 2004 F350 6.0 cclb 6 speed with 260k on it. The previous owner seemed to have taken good care of the truck. It is basically stock with the exception of the blue spring mod, and a sinister diesel coolant filter. Anyways, I brought the truck home and it ran great. Now I have an issue that needs to be addressed.
The issue: I am experiencing a intermittent loss of power, stall, or stumble when engine is cold. After sitting all night the truck will start fine and idle fine. But when I try to accelerate and bring engine RPM up the engine will stumble and lose all throttle response, when this happens the WTS and WIF light flash. Sometimes it just stumbles, sometimes the truck will actually die and then restart. The issue seems to go away after the engine has reached operating temp.
I did some research on the issue and it seems there is actually a TSB out from ford for this issue. It explains that some 2003-2004 6.0's might have wiring harness chaffing issues. This is what the issue I am having seems like to me (shorting harness). I looked up codes on the truck and there is an active code (#8 glow plug circuit fault). I did a short visual inspection of harness and didn't see anything out of the ordinary. But i wonder if it would be worth changing both sides of the glow plug harness?

I have not been on here for a while my X has never had any problems 140,000+ miles. yesterday went out side to start her and let it warm up went back inside to make coffee came out 10 minutes later and found a server oil leak pouring out under the truck. Immediately turned her off popped the hood and found oil all over the back top of the motor? before I start tearing into it, need to know where to start. I've read IPC sensor, CAC hose, anything else to look for?

On the highway doing 100 mph. during af take over, my Ford F-250 6,4 Super Duty 2008, lost nearly all power. (now it is like driving my old hummer h1)
Engine and car runs/starts great, only 10 minutes uptil 60 mph. now.
My mechanic has given up. He checked following:
EGR = OK
HOSES = OK
ERROR CODES = NONE
INTER COOLER = OK
PARTICLE FILTER CLEAN = OK
TEST WITHOUT EXHAUST = NO DIFFERENCE
FLUIDS = OK
Hopefully something I can fix with my hammer. The car has 85.000 miles on the clock.

I have a 04 F250 6.0 and change transmission and transfer case. Now all of a sudden the rear passenger tire is locking up but the rear driver side still moves. I've dropped the carrier and the ring and pinion looks great and so does the spider gears ... Need on whole new rear....

I have a 2001 f250 super duty extended cab with the v10. Over the past week it has been running fine and it will all of a sudden lose power and dies. I've been able to start it back up once right away and a few times it started up after a few hours of messing with it.
So, after the truck dies it will crank and crank but will not start. We have checked fuel pressure and nothing. Then we applied direct current to the fuel pump and it turns on. Then we applied direct current to the fuel pump slot in the fuse box and got a fuel pressure reading of 40 psi. But when we crank we have no pressure.
When we apply direct current to the fuel pump slot in the fuse box the truck will only crank and not start.

I have a 2004 F250. Owned it for a little less than 4 miles (186k on the odometer) .. The other day making a routine run and the radio goes out. Stopped to check it out and found I had no power windows either.
Made it home, checked the fuse on the radio and its good and the the power window fuse is also good. Put a meter on the terminals and have no voltage going to them. What I need to look at???

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.

First off my vents stopped blowing completely. At this time the thermostat was still functioning. Fuse 28 was blown. I replaced the fuse and it blew again shortly after turning the heater on. I replaced the relay and resistor and still blowing fuses. For some reason I tried a 30A fuse and it didn't blow but a few minutes after turning on the heater there was a burning smell. I immediately turned it off and pulled the fuse back out, which was hot. I then replaced the blower motor and at this point there is no power at all to the control panel. The fuses are all fine as well as the relay and resistor. There's power to the fuses. So it seems like somewhere between the fuse box and the control panel I'm losing power.

Okay, so i was driving down the road. Turned around and all of sudden I have no power steering... The fluid is good and I actually just replaced this ps pump 2 months ago.. Also when I hit the brakes they kinda feel weird too like there not working fully or something... Should I just start tearing this ps pump off?

this morning I started my 2004 f250 drove a mile and filled up my truck. Then drove another mile and my truck acted like it was running out of fuel. It was loosing power then stalled out and wouldn't start. About five hours later I tried to start it again and nothing. about five hours after that I tried it again and it started up and drove fine.
My thought was fuel filter or the water trap. I haven't had a chance to open the filters up and check them yet. Today while I was at work I got on here to see if I could figure out what was wrong with it. all I could think of was maybe the HPOP went out or the ICP sensor. Could one of these be the problem or was I right with my original thinking and it's just a fuel filter? First thing in the morning I'm going to pull the filters and replace them.
Could there be something else wrong with my truck that I don't know about? Like I said I filled up the fuel tank then it lost power within a mile and stalled out and wouldn't start back up. Then about 10 hours later it fires up and acts like nothing happened.
