Dies while driving down the road and usually will restart with no problems.Seems to happen more often when it gets hot out. IPR/ICP are good.It took a long time to start once also. I'm leaning toward fuel pump but ?
View 14 RepliesOk, so I have a 2004 F250, with 6.0L. when driving at a steady speed (doesn't matter what speed), the engine will run rough when coming to an idle, and stay running rough until I shut it off and let it sit for a bit.
After I cycle the key a few times it will fire up and run fine, so I came to the conclusion that air is getting in the fuel system. I then took the filter cap off that is located in the engine bay and cycled the key, which produced a lot of bubbles, which I am assuming shouldn't happen.
I guess my question is, should I have air bubbles in the filter bowl, when cycling the ignition?
I just bought a 2007 6.0 with 239k miles on the truck, it has EGR delete and ARP head studs. When i bought it the owner warned me of injector stiction...
I drove the truck for about a week, changed the oil over to Rotella T6 with archoil, and swapped out the air filter so far. (previously was non synthetic rotella). I drove the truck 2 more times since changing those two items and then i had a no start issue.
Scanguage2 said it was FICM sync.....so i messed with the wire loom, and got it to start twice but it died right away. (it had ficm sync, then it died and went back to 0) So i ordered a CPS pigtail and was going to change it out today.
Today i went out and pushed on the CPS sensor directly, charged both batteries and the truck started rough but kept running after two times (still haven't changed the pig tail)
Now it starts but is still running rough.
Scangauge 2 Running:
IPR : 23.8
ICP : 581
FICM SYC : 1
FMP : 48.5
The only code i'm getting is P0269 which I'm hoping is only injector 3, a bad injector wouldn't cause all this would it?
I'm just trying to figure out what i should look at next.
So my truck is intermittently running rough at idle for the most part and sometimes slightly loses a little power while driving down the roads. Seems to run worse as it warms up. When it runs rough it sounds like a cylinder is missing. The truck is throwing code P0269 for Cylinder 3 Contribution/Balance. Smoking isn't horrible coming out of exhaust but it's there and it comes out at a constant rate. The injector has been replaced by the previous owner recently. It has an egr delete, new turbo, ficm, ficm harness, HPOP, and stand pipes.
When I put the starter solenoid wire to the battery you can hear the engine skip. I did a compression test on cylinder 3, put oil in the cylinder and did the test again to find that I still didn't have compression. Assuming that this was an issue in the head I had my doubts that it was a bent valve and it could have been a bent pushrod.
Sure enough I found the intake pushrod for cylinder 3 was bent slightly so I replaced the pushrod. I started the truck again and seemed fine at first but just like before it started to run worse as it warmed up.
I was able to drive it to the gas station real quick to fill it up on fuel and drove back home which is a short drive, but the truck was running worse and worse and it eventually died on me. I attempted to start and had to jump start from my other truck and the 6.0 would not start. I ended up frying the starter trying to start it so I'm taking a break from it for now.... Ended up pushing the truck home.
The only thing I can figure is that I don't have oil pressure in the oil rail which is why it died but I don't understand why the truck still ran rough and pulled up with the same P0269 code....
It only happens on a very Rare occasion.
When Cold, and when I start out as I open the throttle, it suddenly sounds like there is not a piece of quieting stuff on the engine. I mean its like I can hear right into the engine itself.
I back off, It goes away then I dont hear it again for another Month or two.
I have a 99 f-250 with about 250k miles. Truck is completely stock. It recently has developed a problem where when I start it in the mornings it surges at idle, 200 rpm or so. Sometimes it tries to die and did once but started back up. When driving it continues to rev itself up and is jerky. It runs rough and sounds like it could be missing on a cylinder. At other times it runs fine just like normal. Yesterday morning it started with these symptoms so I put in a new ford CPS. It ran great for about 100 miles that afternoon. This morning it started back with the same symptoms. The SES light stayed on longer than normal when I started it, but it went off. I don't have a scanner.
I thought it might be water in the fuel because this started the day after I filled it from my transfer tank. But the water in fuel light has never came on. I put a new fuel filter on it but it made no difference. Have pulled filter three times looking for water but never found a drop. Also pulled several buckets from the bottom of my transfer tank but found no water there either. Where to look next?
I have changed pickup filter in tank and cleaned 2 tube filters in tank i thought that would fix it.
View 3 RepliesMy truck died on the way home the other night. After pulling over it started right up but died three more times on the way home. Changed fuel filters, cps sensor which wasn't bad when tested, checked fuel pressure (60 psi), cleaned egr valve, fcim has 48 volts, batteries have 12 volts. Tried unplugging egr valve and icp sensor. Truck will start with icp unplugged . Ipr, stand pipes and dummy plugs were replaced last year when I purchased truck. Truck will run in park fine no issues idled normal, builds rpms and boost. Put it in drive when it gets warm rough idle and dies but starts right back up evertime. When truck doesn't die it has no power.
View 10 RepliesI have an 07 6.0 diesel and I'm having trouble once it gets hot. It begins to lose throttle response and shakes while cruising and also has a rough idle. sometimes it dies while idling but after cooling off for a few minutes starts back up and runs fine. I've checked the high pressure oil and the ficm and both of those are fine. I've done an EGR delete so it has nothing to do with that either. My MPG also goes way down when this happens.
View 5 RepliesI have a 2007 F350 6.0 Diesel. Truck starts and runs great for about 10 miles and then loses power and slows down til it dies, it does this without any kind of warning and does not rattle or anything. If i let it sit for about 15 min it will start right up and drive fine for another 10 miles or so and do the same thing.
It did the same thing in December but would not restart at all and the ficm was the cause at that time so i went ahead and replaced the ficm just to eliminate it. I also replaced the fuel pump and the ipr and icp valves are good. The only engine code has to do with the fuel level sensor and that has been on for a year. The egr was recently replaced, the hpop is putting out the psi that it is supposed to and there are not any internal air leaks.
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.
My excursion died while driving down the road I lose everything but once I turn the key off and turn it back on it will start turning over again but don't . I let it set for a few minutes and it will start right back up like nothing every happen . this is our only transportation for now. The recent things I've done is change out the radiator and upper and lower hoses due to a tiny crack in the neck. I also changed out the hose from turbo to pipe on the hot side due to wear out hole.
View 14 RepliesMy truck will only stay cranked a few seconds then dies, I have a lot of codes popping up! I was told may be the FICM.
View 3 RepliesI have a 2005 f350 king ranch,I have a kinda weird problem.the truck starts up and runs great as long as I let it get to normal temp.but if the motor is cold it will idle fine but if I goto put it in gear it just dies.sounds like tc is locking but I don't get any codes.
View 9 RepliesSo pulling my trailer and 4x4 and the truck dies without any other symptoms. No check engine light all other electrical remains working. This happened 6 times this trip always while pulling a grade but only after the truck has been running for a few hours. Each time, no warning and once the truck has set for 5 to 10 minutes it start up like normal. The longer i let it set the longer I can run before it does it again. ICP is 550ish at idle, 200ish while cranking. Check the FICM before the trip and it was at 47.5 to 48.5v key on engine off and running. STC, stand pipes, dummy plugs, ball cups have all been done.
View 10 RepliesEarly 2004 (IPC under turbo) 163000 miles. Injectors done last summer. Stock. Got a call that this guy died on the highway. By the time I got there (45 minutes?), it started and ran fine. He drove it for ahile, shut it down, drove it some more and it died again. I finally got it in and looked it over and test drove it. It died on me twice (Both times, I was pulled over and stopped. How lucky is that?) When it died, it showed that the Desired ICP dropped to zero just before the actual and the ICP voltage did. I wasn't watching the Regulator%. Cranking, it showed about 210 ICP and .19 ICP voltage. After it sat for maybe 10 minutes, it finally started.
Now, my question is, do I have a ICP problem or an electrical problem? My thinking is an electrical problem because to me, it doesn't seem like the oil would cool off enough in 10 minutes to allow it to become thick enough to build pressure again. I also noticed that the ICP dropped down to as low as about 590 at low idle once the oil temp was up to about 190, but it wasn't always that low - usually it was around 625ish. I have it idling right now and recording Sync now, but of course it's running fine. If my sync drops out, I need to change the Cam sensor or crank sensor, correct? If it doesn't drop out, I have a ICP problem. Does that sound right?
Truck sputtered and dies and will not crank again. Changed fuel filters and primed them still won't start. Tried the yellow with blue line wire to battery still will not crank. Checked fuses all are good. Batteries are good.
View 9 RepliesParked the truck last night and all was fine. Went to start the truck today and let it warm up before hooking up the trailer and it dies withing a minute. Go to start it again and nothing. End up killing batteries. Checked for codes and had a bogus EGR code P0404. Bogus because the tune I run doesn't have the EGR enabled and it is deleted. Still plugged in though.
Hooked up dual battery chargers and sent the boy to pick up fuel and oil filters and oil. It was over due in both areas. Changed both and still no love. So I drag out the laptop and set up my AE to monitor FLP, FLM, IPR, ICP, ICV, Sync.
KOEO
FLP 11.00
FLM 47.0
ICP 0
ICV .24
IPR 14.25 odd right?
Synch 0
Cranking
FLP 9.6
FLM 47.0
ICP 800-1600 varied the longer I cranked
ICV 2.2
IPR 14.24
Synch 1
still no start.
Still no codes.
I then cycled the IPR through AE a few times and turned the key. Damn thing fired right up.
Idling
FLP 11.0
FLM 47.0
ICP 875
ICV 1.4ish
IPR 26.4

I pushed the RPMs up to 2500
FLP 11.0
FLM 47.0
ICP 2200 iirc
ICV 2.24
IPR 42.0ish
Synch 1
Turned the truck off and restarted it a few times. No issues. Turned it off and pulled the positive cables and put the chargers back on it.
So the question is .....Is the IPR sticking on me? I just replaced the HPOP in the spring along with the up pipes. Made sure everything was clean. I actuated the IPR and cleaned it out. Put a new screen on it had zero leaks.
Currently truck is in the shop after having multiple episodes where it lost power. It has 47,000 miles on it. When pushing down gas pedal, just does not want to go. Very slow to shift through the gears and get to highway speed. Turbo was not there, and there was also a hard shift/jerking from 2nd - 3rd. Did notice the traction control sensor kick on a couple of times....which was just replaced since a hole rubbed through the wiring. (took it to Ford twice before they found the problem)
They told me today that the code generator said to look at wiring but they did not find anything (heard that before) and that the fuel is possibly contaminated with DEF. If that is the case, someone is messing with my truck! What I don't understand that if the DEF does turn out to be in the fuel tank, wouldn't we have the problem continuously and not intermittently over a month after driving thousands of miles and going through numerous tanks of fuel? We drive and average of 60 miles per day just for work, half interstate/city.
I am still trying to debug my 7.3 running sluggish in the 1200-1800 rpm range. The problem is intermittent. I checked the wiring harness under the valve covers to verify they are plugged in and there are no opens in the circuit. I replaced the crankshaft position sensor and the high pressure oil sensor.
This will run fine one time and a few miles down the road it will chug and smoke out the exhaust until I either get into the accelerator or back off and re press the accelerator. Again, it does it intermittently hot or cold.
I ran both a cylinder contribution test and perdels with a Snap On Verus. The cct passes everytime. The perdels have a couple of cylinders 5-6 and 8 fluctuate between 0 and 1.80% with #8 up to 2.5%.
My question is. Do the cylinders in the test correspond to the actual cylinders in the engine? Reason I am asking is the Verus does not follow the firing order on a gas engine. The cct is in order of 1-8 and I have to correlate the cct order to the firing order. Found this out the hard way when I had a bat cop on a 5.4 and replaced it only to have the same cylinder still show not firing.
I got out the graph leads and tested the cylinder and pulled the injector thinking it was bad. Everything showed good but the cct still showed it not firing. I had to unplug each coil and watch the cct to determine what the true cylinder in the test was. It turned out to mimic the firing order so I am asking out of concern that cylinder 3 in the perdels is really cylinder 3 or a different cylinder.
Btw, the perdels all show 0% if the transmission is in drive. I would have thought that a load on the engine would have showed higher perdel percentages with a load on it.
My ABS light keeps coming on randomly. Sometimes it's on for a full day sometimes a few seconds. It's pretty weird because it doesn't throw a code or anything. Where to go from here.
