Ford 6.0L Power Stroke Diesel :: 2007 - Won't Start Intermittently - Running Slightly Rough
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.
Ford 6.0L Power Stroke Diesel :: Intermittently Running Rough At Idle - Code P0269
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 The injector has been replaced by the previous owner recently.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....
Ford 6.0L Power Stroke Diesel :: 2006 F250 Running Rough At Idle
I have a 2006 f250 with a 6.0 with sct livewire, arp studs&gaskets, oil cooler, blue spring mod, sinister egr cooler and it had been giving me some real troubles lately. Started off as a code for injector #8 so I replaced that and while I was in there I rebuilt the oil rail with new nipple cups and orings, replaced standpipe and dummy plug in that bay(also updated the arc fitting less than a year ago), new exhaust back pressure sensor tube because it was right plugged with carbon, and a new egr valve because that was right packed with carbon as well, all backed together and torqued to spec from the Haynes manual and the truck still sounds like its missing at an idle with some light smoke(just smells like unburnt fuel). From there I went to test the ficm which is also only a couple years old and it seems to stay at a constant 48v so at this point...

When I first start my excursion in the morning, it starts fine, idles fine. If I don't let it sit for about 5mins plus i have this issue. I will start off and it has no power at all. I can barely get up to 20mph. It doesn't seem to want to change gears, I don't hear the turbo spool up. Then all of a sudden it will go to next gear, turbo spools up and it has power again. It is like I said a 6.0 power stroke, its a 2004 excursion with 214k miles.

2004 Excursion... 1st time into a 6.0 for me so I took my time. Truck has 192000miles.
PHP Ficm atlas 40, 58V Swamps
SCT Tuned via X4 (recently)(Extreme street at the time)
Synthetic 0w30 summer and 0w40 winter.
FORD filters ALWAYS, 5000mile intervals no pushing it
FORD fuel filters, BOTH regularly.
Studded, AFE Stage 2, Liberty EGR Delete.
42's, 4:88's with Detroit in rear
Highway driving and feel a stumble. Weird, then another, ok that wasn't a bump. Then steady rough idle and a heavy vibration when I lightly got back up to speed to get myself home.
Had new filters so started there. Just changed in the spring here and they were in pretty new condition but swapped them out anyway. Stripping the cap, 120 bucks and had to put a new one on.
Start truck and still rough idle, test drive and still a bad vibration.
SO, I read and search. Scanning with Ford or AE are my number one priorities and they were done along with Fuel pressure check.
Scan revieled Inj 6 out, fuel pressure at 60 PSI. We pulled plugs off injectors with results except 6, confirming it's not working.
Ordered an injector and the Aliant Power rebuild kits to freshen up the other 7.
Disassembled all 7, NO stiction problems at all and all 7 spool valves were clean as a whistle. Bodies of injectors were good on 6 of them and had a screen in cyl 3 what was completely gone (the 3 screens around the body of the injector). Tip was also plugged but one hole. (used brake cleaner in tip and air to confirm 6 holes were clear) Used the body of the core on that injector but not the spool part. Replaced all O-Rings incl the seal inside the top where rail snaps into. Sanded spools (800grit 2-3 turns) and installed same way they came out. Stem pipes and dummies new as well.
Reassemble, carefully and fire truck. WOW....running abit rough but smoother. Ive read it takes abit to get air out of system and to expect longer cranks ect. Shut it down. INspect for leaks. Button up the ficm, and few other things. Re-fire truck with abit longer of a crank. Fires and running smooth. HERE's where it starts acting up again. I can feel a small stumble....then another....then full time again. Exact same as before. Pull 6 off and it's that injector again.
Here's the big mistake I made. Reinstalling injectors, I put the new one in #4 spot and number 4 in 6's spot. Not smart, I know.
Pulling inj plugs off around entire motor while running and def No 6.
Put things away, call buddy and he says possible FICM. or harness.
So i pull inj harness and OHM every single pin and map it. 100%, I go grab his "good" ficm and test with that. HOLY COW, FOUND IT. Started great... Then as she warmed up ICP at650ish, EOT ECT getting to 100-110F (only a 4-5* delta always monitor) is starts to vibrate and run rough again.
Read some more....OHM testing is one thing, actually load testing harness confirms if it's actually no good. Harness is 450 bucks plus our lovely 13% tax so I want to diligently cross this bridge. Grab a harness off a running 6.0 and test next day.
Fires up and runs smooth. Then, as temps come up it starts again. Walked away last night and when I fired up this morning. Started great and as she warmed up vibration was back. Along with a intermittent squeak from the turbo housing area.
Codes.... SCT X4 tuner is reading nothing DTC's and hasn't since day one so I "assumed" no codes until buddy scanned with AE and since it's last WiFi update wouldn't connect to computer and gives me error code 10007 when I try to tune. **Ended up fixing last night, went into another "Tune revision update" and now connects to my computer AND returned my truck to STOCK and resested truck. Still running rough.
So I plug my PHP FICM tuner and get codes:
P1102 "Unkknown" (reading here I had my AFE off and not plugged in)
P0113 Intake air HI input
P0284 Cyl 8 cont/bal Fault
P0603 Internal control Module KAM error
P0611 FICM Perf (58v swamps, I've read always throws this code and I've had that code since day 1)
P0676 Glow #6 fail
Lastly I'll add, no smoke out tail pipe at all during all testing minus the black puff when tune loaded.
Ford 6.0L Power Stroke Diesel :: 2004 F350 Running Rough / Misfire On Cylinders
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.
View 14 RepliesFord 6.0L Power Stroke Diesel :: 2004 Excursion Running Rough / Smoke Coming Out And Stalling
I have a 2004 Excursion with a 6.0 Bought the truck already studded, EGR deleted, and a 54V FICM. When I bought the truck it had a hot stall, no restart problem. Found the high pressure oil leaks and resealed them by replacing the #3 injector and replacing the top injector seal in the #4 .Oil pressure reads very good now and I drove the truck for a couple weeks problem free.
Truck started smoking (white to gray) and felt like it had a miss. No misfire or contribution codes. Truck failed the bubble test and I narrowed the leak down to the passenger side by removing the banjo bolt
Banjo bolt at the front of the passenger head
Found the #3 injector loose...the copper washer
Copper washer had disintegrated/melted and appeared to be stuck to the side of the injector. Scraped off easily enough, cleaned up the injector and injector cup and reinstalled the injector with new O-rings and copper washer.
Put the truck back together and still smoked the same and still felt like it had a miss. Ran KOER test and found sometimes a contribution code for #2 and sometimes #6 .
Drove the truck to work and it didn't feel down on power...mostly just smoked and rough idle...but on the way home there was a lack of power and just as I pulled into my driveway the truck stalled...wouldn't restart. FICM voltage was good, high pressure oil read over 900, IPR was holding around 40%.
Pulled the secondary fuel cap
Secondary fuel cap to run another bubble test...there was no fuel in it...completely empty. Started to think that I had a fuel feed problem. Hooked up a fuel pressure gauge
Fuel pressure gauge and drove the truck again...pressure wasn't great (45 lbs) but never dropped below 42...not even when it stalled. Pulled the cap again...dry again...yet the truck read fuel pressure.
Research showed that I was possibly pressurizing the fuel system with combustion pressure and that was possibly displacing the fuel from the fuel system. This would explain the run for a few minutes, then stall and no restart for a few minutes...I'm assuming that the pressure would bleed off and the fuel pump would start over.
Still failing the bubble test and still pointing to the passenger side. I pulled and recleaned the injector and cup...new orings
oRings and copper washer. Bubble test again...fail.
Pulled glow plug from #3 , failed bubble test still.
Pulled glow plug from #1 , failed.
Pulled #5 , failed...pulled #7 ...failed.
With no glow plugs in the passenger head I am still bubbling up to the fuel filter housing. Pulled the banjo bolt from the front of the drivers side head...no more bubbles.

I'm new to diesels. I just bought a 2004 F250 with the 6.0 V8. I have the high and low circuit, contribution codes on cylinders 4 and 8. I've only had the truck for a few days but I've been reading a ton. The symptoms are hard start, rough idle/shaking, no power when cold. When it heats up and I'm over 2000 RPM it seems to be just fine. Even when hot and below 2000 RPM it does ok. I've check the FICM. It reads 48V with key on and 48V running. My plan is to do the following:
Change the Fuel Filters
Change the oil filter
Change Air Filter
Change oil with 5-W30 synth and I have both Hot Shot/Rev-X
If that doesn't work, I'll replace the two injectors. How does that sound.
Ford 6.0L Power Stroke Diesel :: Dies Intermittently While Running?
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 RepliesFord 7.3L Power Stroke (1999-2003) :: 2002 F250 Idling / Running Rough And No Power
2002 F250 7.3L suddenly idling and running very rough, and doesn't have any power. Truck has been running perfect, it's my daily driver, and just put a couple hundred miles on it yesterday with no problems. I had been having some transmission issues when I tow heavy so I bought a new transmission yesterday. This morning I pulled the truck into my garage to change the transmission. Again truck ran fine, no signs of any issues before the trans swap. I changed out the transmission, which included unhooking the trans wiring harness from all the various sensors, and unbolting the starter.
I didn't mess with anything in the engine bay except for unhooking the batteries. I had also repaired the overdrive button wires, as they had been pinched in the steering column and the button wasn't working. When I got everything hooked back up I cranked it up to get the trans fluid flowing through the transmission, it started right up and idled good. I had it running for a few minutes and it was beginning to make a little more noise than usual. When I started to back out of the garage it was getting pretty rough, almost like it was running out of diesel. I put it in neutral and gave it some throttle and noticed I was getting white smoke out of the exhaust and could smell diesel pretty strong.
I checked my injector resistance at the valve covers and got around 4 ohms +/- on all of the injectors. I rechecked all of the clips and harness that I had messed with. I took a look at the ICP sensor and it has oil in the connector which I know can cause a rough running condition in some cases. It looks like it has had oil on it for a while. I unhooked the batteries again for about 20 minutes to try and reset anything that may have messed up. I checked a bunch of connections under the hood to see if anything was unhooked or loose.
I also cleaned up the connector on the ICP sensor. I started the truck back up and it idled perfect so I pulled it back out of the garage and headed down the driveway. It almost immediately started running rough again and barely had the power to go up a small hill. I pulled back in and tried unplugging the ICP while it was running, which made a slight difference in the idle but still very rough. I plugged it back in and the idle progressively got worse until it was chugging really bad. I shut it off after that and haven't messed with it again.
What might have happened? Could it be a bad sensor or transmission position sensor in the new trans? Is it just coincidence that this happened with a transmission swap? I am going to get a new ICP, but if there is anything else I can try/check before I can pick up the ICP on Monday let me know.

Well, I've read a lot of threads on this problem! Try to do my own repairs, so I'm learning and not spending a lot of cash at repair shops.I have an 04 6.0 Super Duty Crew. Starting running rough on way home. Pulled over ,then it died.wouldn't start. Had towed home. Replaced ficm circuit board. No start. Replaced Harness,
icp...... ipr Sensors. Still no start. I noticed there is another circuit board inside ficm. Should I have bought the whole ficm unit?
Ford 6.7L Power Stroke Diesel :: Running Rough / Reduced Engine Power
I am having a problem with a 6.7. The truck has 9900 miles on it. It has a dpf delete, egr delete, Spartan tuner and a snow stage 3 kit. The truck lopes at idle but once throttle is applied it levels out but still runs a little rough. Its keeps saying its in reduce engine power no matter how many times I clear the code. If I clear the code it will come back in 2 seconds with out cranking the truck or anything. Rail pressure is telling me 31090 psi and not changing running or not. I have changed rail pressure sensor, and pressure control valve with no result. The green and violet 5 volt reference that feeds those sensors is only putting out 1.2 volts. Put a new pcm in it still the same and now has quit running totally. The codes are P0193, P0335,and P06A6.

I got a 2005 f350 6.0 deleted and studded with air dog 2 4g pump, 125k miles. It started running rough then just died all within a few miles tuner showed code for injector 6 and ficm towed into ford dealer didnt have time to mess with it. They said ficm was bad had them replaced it then they said i need whole new fuel system lines,harness,pump,sending unit ,tank the whole 9 yrds. Which i thought was uncalled for so i called up airdog which system i had on there and they laughed and said ford garage is full of bs that they will upgrade my pump to the 4g and new harness.
So I took that stuff to garage had them swap it out and now they said come get the truck they wont work on it anymore that now it needs 3 injectors and they wont touch it with aftermarket fuel system on it. So I go to drive it home and it starts but runs rough and u can hold it to the floor and it wont budge bearly idles up and builds no boost my tuner is showing injector 2,3,4 now which wasn't a problem before i took it into the garage. So im not sure what happened to cause this all to happen but before i sink any more money into it is the 3 injectors enough cause to make it not build boost now .
Ford 7.3L Power Stroke (1999-2003) :: F250 Surging - Running Rough - Dies?
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?

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 6.0L Power Stroke Diesel :: Intermittent Rough Running At Idle
In your experience, what issues have you seen that caused intermittent rough running at idle, but did not throw a code. I have monitored (with numerous scanners/gauges) this 6.0, but cannot get a code or see any of the sensors out of spec.
At Hot idle:
IPR: 24.2
ICP: 640
ICV: 0.90
MAP: 14.7
MAF Volts: 1.5
EOT/ECT Deltas within 10 and Avg ECT=192, EOT=199
EGR Valve cleaned and EGR demanded = EGR Measured
Vehicle will run rough after long runs or towing. Cylinder Balance test showed all injectors on. What could be the cause?
