Ford 7.3L Power Stroke (1999-2003) :: Truck Running Rough And On Less Than 8 Cylinders
I had an HPOP line burst and soak the engine compartment with oil. I replaced the line and degreased the engine and rinsed it off. I started the truck and let it idle for 15 minutes or so before driving it. On the way home right after a shift it started chugging and running terribly. The check engine light was on as well. I limped it the mile or so home and shut it off. I restarted it and it runs just fine. I checked the DTC's with Forscan and there were a bunch of things that were mostly related to the HPOP and the MAT sensor that was shredded when the line blew. I left the hood open to dry out today and I'm hoping it is just some water in a connector. Does that sound plausible?

My truck is skipping but if I give it more throttle it will stop but then will start back when I let off the throttle. It seems like it is only running on half the cylinders. This problem is intermittent which makes it very hard to troubleshoot even for the dealership and other places I have taken it. Also, the problem is temperature sensitive. It only does it below 40 deg. F. Truck runs fine any other time of the year. Truck has new plugs, plug wires, distributor, egr valve, O2 sensor. Also, the IAC has been cleaned. The check engine light does not come on.

I have a buddy at work who has an 04 f350 6.0 that is running very rough. we put a scanner on it and disabled the injectors and 1,7,8 have no change. He checked the FICM voltage and is getting 48 volts on crank and run. He checked the wiring for anything loose or rubbed but nothing seems wrong.

Oil temp sensor - when I turn the truck on - it goes right to half way. I am guessing it is broken ? But then again, if it was broken, why would it go half way ?
View 5 RepliesFord 6.0L Power Stroke Diesel :: Truck Is Starting To Surge A Bit Like ICP Sensor Going Bad
I started having an issue with a rough idle soon after startup about a month ago. I thought it might have been stiction so I added some Archoil stuff the other day to my oil interval change and although I have not put too many miles on it, the rough idle is still there.
At startup the engine runs great. I did notice a few times a little longer than normal crank (~3 seconds) where other times it fires up in less than 1 second. This has happened twice in the last month. Once the engine runs for about a minute I get an uneven idle......I wouldnt necessarily call it a miss per say. I took some readings for the ICP and IPR and can provide them if someone needs them. Once the truck warms up it seems to idle better but still not 100%. I have no power loss, no hesitations jut a weird idle with intermittent surging while in gear.
The truck is starting to surge a bit like an ICP sensor going bad but not as pronounced as the last time this happened to me 4 years ago. Basically trying to get opinions as to what it might be or what to check next. I am leaning toward one of three things.....stiction, ICP or IPR valve (original). FICM voltage is good but my fuel pressure gauge broke, but the blue spring upgrade I did.
Ford 6.0L Power Stroke Diesel :: Truck Would Die After Starting Then Start Up Again After A Minute
2004 6.0 Diesel. First the truck would die after starting, then start up again after a minute. Then the truck wouldn't start at all.
Trouble codes indicated low voltage on all injectors leading me to conclude a dead FICM. Replaced the power module in the FICM and reinstalled, but still no start.
48V at driver's side screw under the cover. 12V at the next screw, the next appears to be ground. The passenger side screw is 0V. One post indicated that should also be 48V - is the true?
I probed the power coming in - logic fuse is good. 50A fuse in the cab is good. Relay seems good.
The Ford FICM diagnostic indicates 12V power should be coming in on FICM connector X3 on pins 7, 8, 4, 23, 24, 25. I have 12V only on pins 7, 9, and 27. When I pull the relay I lose power on pin 27.
Ford 6.0L Power Stroke Diesel :: Truck Dies Within A Minute After Starting
Parked 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
Synch 1
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.
Ford 6.7L Power Stroke Diesel :: Truck Running Empty At 50 - 55 MPH
Finally, you can get EGT's with the Torque app!
I had to reinstall Torque on my new phone and EGT1 was in the predefined set of PID's for Ford. Launch Torque, the go to Settings, Manage extra PIDs/Sensors, Menu, Add perdifined set, select "Ford (Incl PowerStroke)". I believe it's getting data from EGT11 that is between the turbo and the DOC.
I included a graph that shows the truck running empty at 50-55 MPH, ambient air temp. ~50F and the EGT's are around 430F, at 60-65. They are 480-500F. If one of guys/gals with the Edge Insight/H&S/other tuner would be kind enough to confirm those numbers are correct.
This was on a 2 lane highway following a couple of old rock haulers, then I passed 'em.
Ford 6.0L Power Stroke Diesel :: 2003 F350 - Truck Not Starting When At Operating Temp
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.

Ford 6.0L Power Stroke Diesel :: Truck Got 4 New Injectors But Still Running Rough
My Excursion got 4 new injectors a couple weeks ago and when I got it back, it was running rough. My mechanic told me it was going to take about 100 miles for them to break in.
300 miles later and it is still running rough. So I opened the hood, took a look around and saw this wiring harness unplugged. Where it goes? Youtube video shows where the harness is [URL] ......
Also, my truck has been shaking violently at 50 miles per hour, unless I hit tow haul, then it is moved up to 60... I am assuming its connected some how to that wiring harness being disconnected.
Ford 6.7L Power Stroke Diesel :: Compressor Kept Running For A Few Seconds After Truck Was Off
Strange thing happened yesterday and again today. I have my compressor hooked up to up fitter #3 ,turned it on yesterday to fill the tank back up to 120psi. Before it filled up i shut the truck off to fuel up..but the compressor kept running for a few seconds after the truck was off. and today doing some running around the compressor turned on out of the blue when i was driving..but the switch was off.
The shut off switch (on the compressor itself) turns it on at around 90psi and shuts off at 120, but the thing filled my tank to 180 before i noticed it was on, pulled over to shut the truck off and again it ran for 10-15 seconds after the truck was off. I'm pretty confused. maybe it has something to do with the build up of snow under the truck, we just got 16" two days ago. but still when the up fitter is off shouldn't that cut the power from the accessory hooked up to it?
Ford 6.0L Power Stroke Diesel :: Truck Running Rough When Cold
My truck was running rough when cold, I went to check the ficm voltage while wife was cranking and coolant shot right into the ficm and cooked the sumbitch. Stop laughing that stuff happens to me all the time. Anyhow, got a new ficm and truck wont start. Starter kicks out after a few revs. I ran my own solenoid wire to the starter and it cranks just fine. ficm at 48.5 koeo and cranking, icp 1100+, ipr from 14.8 to around 40%, ...
It takes a few seconds for the cam/crank to sync but it does. I changed the fuel filters and primed it, Got new batteries, and threw a crank sensor for s+g. With the key on and me cranking it using the solenoid wire, it almost starts. But from the key it will kick out after a few seconds. All fuses and relays are good. I hear the pcm also controls the starter, could that have cooked when the ficm went or would it blow a fuse? Diagnosing using a scangauge2 ....
Ford 6.0L Power Stroke Diesel :: 2007 F350 Not Starting - Running Rough - FICM?
I just bought a 2007 F350 6.0 two days ago, so I was giving the truck a good wash today using a electric pressure washer. The engine bay was pretty dirty so I decided to take some soap and a brush to it. After cleaning it I let it sit for a while in the sun to dry. (engine was stone cold). After it had completely dried out I go in and it cranked right up. I let it idle for a good minute-minute and a half put it in drive and pulled away slowly, right when I touched the accelerator it started running rough, so I popped it into neutral and let it idle for a sec but it was still running really rough so I cut it off not wanting to damage anything worse.
I let it sit and tried to start it again, it just turned over and over. I checked the oil level it was good. So I pushed it back into my driveway to figure it out. I took ICP connector out and tried to start it, just turned over and over. took fuel filter out it was just replaced 2K miles ago it looked a little dirty but not super bad. I put that back in. took icp out again and tried to start it and it started but ran super rough and was dumping black smoke out.
I checked back all ficm connectors and they were all connected. I haven't checked the voltage on that yet, but plan to do that tomorrow. the previous owner had the ficm go bag about a year ago and he sent it off to ficmrepair.com and they fixed it for him. also he had the stand pipes and dumby plugs done as well as the stc on hpop. im kinda at a loss on where to go now other than to check voltage on ficm.
Chevrolet - 1500 :: 2001 Acts Like Running Out Of Fuel When Gas Tank Is Over Half Full
I have a 2001 Chevy Silverado with the 4.8L V-8 engine. It acts like it is running out of gas ( the gas tank is over half full). The truck has sat for about 6 months in this condition without being started here in Sacramento, CA. I then replaced the fuel filter and for a few minutes it started and the engine ran fine (without actually driving it). A few days later I started it again and it now again acts like it has fuel starvation, it will rev up briefly then act like it is running out of fuel. I know the fuel pumps are the Achilles Heel of these trucks, but before I try changing it I was wondering if there might perhaps be another problem such as the new fuel filter plugging up quickly or possibly an electrical problem. I've always heard these fuel pumps either work or they don't work, nothing in between. This problem is intermittent but big enough the truck is not driveable. Is there any way to get a good take on the problem before diving into the fuel pump replacement and hoping that solves the problem ?
View 5 RepliesFord 6.0L Power Stroke Diesel :: 2004 Truck Died While Running / Won't Start
Last friday, my truck died while running. I let it sit for a few hours, went out and it started right up. Went to get pizza for my kids and I got 5 blocks from my house and I barely had any power. Truck died again while getting pizza and had to tow it home. Now it will not start. I have checked fuses, taken apart the fuel pump on the motor and cleaned the water from it, added a fuel treatment and also did an old truckers trick with the fuel (10% gasoline). the truck will crank and make an attempt to fire but it will not start. I have 3 kids and this is my ONLY transportation. I need to get this thing running STAT.

So I put in new clutch yesterday. Reverse works, granny works, 3,4,5 work. ZF6 manual. But when I try to go 1st or 2nd. Its as if the truck is in neutral....what should I be looking for. I bought the truck having only knowing the clutch was completely shot, was not told about this 1&2 gear issue....
Do I need to pull the trans out again... or is there something I can see or adjust, because from what i can see where the shifter connects there is no adjustments. Is it probably a gear selector fork...or connection that took a crap. when moving in granny gear i did not hear any irregular noises....
Ford 6.0L Power Stroke Diesel :: Truck Will Start Running Really Rough After Filling Gas Then It Will Clear Up
I have an 04 F2 50 with 6.0 with approximately 225,000 miles. I filled up with gas last Wednesday and every so often the truck will start running really rough and then it will clear up. Is it possible to of gotten some bad gas if so what products are out there to clear that up. Could've been injector going bad what are the best products for cleaning injectors. No check engine light on, gauges are good, nothing different on the scan gauge.
View 3 RepliesFord 6.0L Power Stroke Diesel :: Running Rough After Putting Fuel In Truck Now Won't Start
This has me puzzled to no end. After my son had put fuel in my truck it began to run rough, and had to be towed home, and now won't start. Now the first thing I thought was that he put regular gas in. But he was sure he had not ,and the receipt from the pump indicates diesel. It was hard starting before this happened.
1st Misfortune of having gas put in instead of diesel and did your vehicle run afterwards.
2nd Here are my readings from my scangage:
Sync Yes/1, Ficm main power 48.5 v, ICV .17 (2.01 when cranking). ICP 1572. IPR 50.7.
Checked upper fuel filter for bubbles, none.
Engine oil pressure comes up immediately on cranking.
Don't know what else to check, these readings look fine to me. Only the fuel is something I'm not 100% sure of. It does smell like diesel not gasoline.
Ford 6.0L Power Stroke Diesel :: 2005 Missing / Truck Started Running Rough
So I have been fighting a rough running, missing problem. My truck started running rough one day on the way home. I got it scanned, it showed injector contribution balance 1&2. Made sense to me that it threw those codes. I replaced 1 and 2 with oem replacements. Got that all done, truck still ran like crap. I changed fuel filter with motorcraft ones and drained the water separator. That didn't work. I am getting it scanned again, so i will have codes shortly.
Also, for a while it would run with absolute no problem. It was intermittent like that. Run bad run bad run bad and then one day run flawlessly. I though it was electrical. Checked all the common places for chaffing, saw nothing. Even did the wiggle test while it was running, no change. But it hasn't been intermittent for a while now.
