Ford 6.0L Power Stroke Diesel :: Running Rough / Crank Position Sensor Codes
Apr 8, 2015
It's an 04 F250 with the 6.0, and has been there about five months now. The backstory I have been given is that it drove in running rough, gave crank position sensor codes, and the CPS was replaced. That was the last time it ran. Since then, it has had the CPS replaced five times, the FICM rebuilt then replaced three times, the engine harness replaced, and spent some time at Ford. It would only show about 30rpm while cranking. The engineer came and looked at it, said it must be the tone ring on the crank and that's it.
Here's where it's at for me: Cranking RPM peaked out at 57, but the fan rpm was about 180 while cranking and it sounded like it was cranking pretty quick. I disconnected the glow plug module, had another guy crank it while I gave it a quick shot of starting fluid, which it caught and started to run on. It sounded like it was running on fuel for a second, then shut back off and now cranks unevenly.
According to the owner this thing has seen lots of starting fluid in the course of diagnosing it, and there were no odd noises before it shut down so I suspect stuck valves from sitting so long. It did give me a whole bunch of codes which I will post tomorrow, including injector #4 high. I tried to do a buzz test but just got a message saying "unknown code, please wait" and then nothing.

I have an 05 f350 6.0 that I recently bought. It was fine until a few weeks ago when it died while I was driving down the road. I pulled to the side and it started right back up like nothing happened and kept driving like normal. Skip to last weekend it did it to me twice but the second time it would not start so I plugged my programmer in and it showed p0336 crank position sensor and cam portion sensor codes (I can't remember the number of the second code) I have read a few posts that said maybe it's the icp sensor so I went ahead and replaced that with no luck. The batteries went dead from excessive cranking which I know isn't very good for my starter but I was getting a little upset.

ok i have a 2004 6.0 that has been a pain for the last 3 months so much so that i have replaced all the injectors,fuel pump ,water pump ,ficm, batterys , now 4 days ago i was driving and the truck stumbled for a second but i brushed it off as maybe I still had air in the fuel and the truck drove as it should .. now fast forward 2 days and whil driving it just died so I put the shifter in nutral and it fired right up in 2 seconds then it runs as it should for about 10 minuets then it died again and fired right up .. while i was turning around it died 3 more times but would crank and run then just 3 miles from home it died and would not crank . when I got the truck home I hooked up my computer and had a cam position sensor code so it sat for about 3 hours and as luck would have it it fired back up and run fine i once again checked it and the same code was there now its today and I once again fired up the truck and i checked every wire for chafing and I could not find any i even checked it while running and nothing so I drove all over the yard and the truck run great until it reached a temp of 191 at which time it shuttered and died I could crank iit back up then it would die again but now I have no codes and my icp and irp seem fine here is a screen shot while the truck is running.

I've got a 2004 6.0 4x4 broke down in Gillette WY that will crank but won't start. We've had a cert. Ford mechanic bring out the computer first time it showed the IPR valve so that was replaced. Now it's not throwing any codes. We had it running for about 2 hours a week ago but the next morning it wouldn't start again. We're at a loss of what else to check. Here's what we've checked & replaced so far:
2 new batteries
New ICP Sensor
New IPR Valve
New #6 Injector
New Cam Sensor
Checked all fuses and relays
Oil is good
Coolant is good.
High pressure fuel test checked ficm 48 volts as it should be.
It's not the hpop because oil pressure stays up when cranking for fifteen seconds.
Cleaned secondary filter housing.
All filters are good.
Checked fuel pump it's good. ....

Was trying to give back to FTE, all have been useful. So I figure I would post a problem solver. Had a nice oil leak traced to cam sensor o ring. All back together now crank no start.
Truck is half in and out of the garage, torque pro isn't pulling any codes. I did accidentally pull my alternator cable out of the connector, luckily had one to replace.
Did I wreck the sensor taking it out? Will have to try and pull the beast out tonight.

Anyways, so if replace an egt sensor how soon do I have to clear the code after install of a fresh sensor? Could I replace it in my garage and then head to autozone and borrow their scanner or do I need to do the replacement in their parking lot and do it right after the installation? It's my old mans truck and he doesn't have a scanner for his rig.

E99 Romps on start up and randomly dying. Bought this truck about 3 weeks ago. Previous owner mentioned he had issues with it getting hot and shutting off and not starting. Has new IPR, ICP and pigtail, I just put in a new fuel filter. Has 206k miles on it and is the 4R100.
The past two days after sitting all night I have been cycling the key twice and it hasn't done its romp. Typically when it does I can tap the pedal once and it goes away. This I could deal with but its started to die randomly while driving, never while cruising down the road. Its either just after starting it and rolling slowly or slowing down for a stop or to turn. When it dies, I can put it in neutral and it fires back up no problem. SES light usually comes on for about 10-15 seconds after but goes away.
Replaced the grey CPS that was in it with a dark grey one from RiffRaff Diesel. Got a Edge CTS2 to figure out the problem, the codes Im getting are P1280 and P1247.
The ICP pigtail they replaced they spliced on with butt connectors. I plan on pulling it to check for oil and make sure it does look new and redo the connections with solder then shrink wrap them.
I was told to check the IPR% under full throttle which I did and it never went higher than 36.7
The truck did start running rough around 45-50 mph and I did get a video of the ICP jumping around while cruising down the road.
Then I went through a drive through and the truck kind of hiccuped like it wanted to stall and the ICP went right to 725 PSI and idled up and stayed there until I started to leave.
Truck is pretty much stock, K&N air intake and muffler cut out and straight piped.
Here is a link to the videos I got :
e99 7.3 ICP fluctuation while driving - YouTube
e99 ICP steady at 725 PSI after acting like it wanted to stall. - YouTube

I just got a new 2006 E-350 van about 4 months a go (my previous 2004 got scraped - found out the fuel line leaving the secondary filter into the engine with clogged with bits of paper (wtf?)... after I decided salvaged it for parts for my new van...).
New van drives beautifully in the last 4 months without problem, but shut down on me on the highway yesterday. No strange noise or anything when it went out. I managed to coast safely to the side of the highway. Unfortunately, I cannot seem to start the truck again and had it towed home. It cranks, but doesn't start.
I have a scan gauge ii this time and it shows the following:
KOEO:
FICM ~48.5V
ICP 0
IPR 14.8%
Sync 0
Cranking:
FICM ~48.5V
ICP ~8PSI
IPR 84.7%
Sync 1
I still have a P0299 and P2262 check engine code from 2 days previous to the above, but this doesn't seem to be related to the no-start conditioning (both turbo related)
So, pretty much, I'm looking at a very low ICP. Some research indicates this is is due to a bad HPOP, bad STC fitting, or a massive leak. Given the really low ICP, can I rule out the STC fitting and leak? Looks like only the LPOP is providing pressure. Is there anyway to tell if the HPOP is dead or not once I remove it?
Anything I should shot-gun replace first? I have a bunch of salvaged parts from my old van in my garage, which doesn't include the HPOP unfortunately.

2007 6.0l cranks but no start. Read all the forums and I think I performed all the checks. Getting a ficm/ cam sensor/crank sensor no sync. I'm also getting 84.70% at the ipr while cranking. Do I have multiple problems? Watched videos on either the ficm or ipr percentage but not one that had both problems. Getting injector clatter and fuel pump runs. Didn't see anything obvious with the harness.

Driving home from work last night my truck just died. I was under load, going up hill, and she just shut down. No power, completely dead.
She'll crank, but not start.
Ever hear of this?

As the title says I am suddenly having a long crank when starting and low oil pressure when when warm (above approximately 100 degrees). IPR goes to 85% when cranking. Stored codes were P2290 and P2291. Other symptoms are low power and what sounds like a power steering pump with low oil whine and low power. (It is not power steering related however, I checked.) I pulled the oil filter and cranked engine and filter bowl filled in less than 10 seconds.
Oil did have a fair bit of air bubbles. Oil has 5000 miles and is Motorcraft 10w30 diesel. I have not added any since the last change. I do not have the new style pump so it's not the STC fitting. What my issue is? I do have AE if any other info is required. Particulars are in sig. The searches I have done combined with the mileage I have lead me to either the low pressure pump is failing, or the high pressure pump has lost the ball bearing out of the side.

I have a 2011 F450 with a 6.7. It has 99K. The whole fuel system was replaced about 10K miles back. I installed a dieselsite aux fuel filter/water separator after that. Has been running like a top till this am on the way to work. Right before I get to my biz the reduced power warning came on, fortunately I made it into the parking lot at my biz. Then the engine died and it would not restart. Hooked it up to auto ingenuity and I got the P0087 code. I changed the diesel site fuel filters and the stock primary and secondary fuel filters.
The diesel site had a little bit of sediment but no water whatsoever. The Ford filters were very clean and had no trace of sediment or water, but I replaced them anyways. I cleared the code and tried to restart the engine but it will not start. Checked for codes again and now has P0087, P2291 and P2539. The pump is kind of loud when trying to prime the system but there is pressure to secondary filter on engine. I do not have a gauge and adapter to check the pressure yet. I did pick up a replacement pump before the parts dept closed. Could the pump still be bad even tho I do have pressure at the secondary filter?

I have a 2007 f-250 6.0 liter turbo diesel. I was pulling a trailer with a golf kart on it and was not in tow haul. I was going up a hill and it shot up into 5th gear. I pulled into my house and shut it off and refired it and it acted fine. I went on a little test drive to see if it was going to do it again before I went on my trip. As soon as it shifted into third gear the tow haul light started to flash on my dash and went to 5th gear and would not down shift even if I did it on the column.
I scanned the truck with my snap on modus and it gave me these codes. P0706-transmission range sensor A circuit range/performance, P0707-transmission range sensor A circuit low input, and P1702-transmission range sensor circuit intermittent. I put a transmission harness in it and started it up and it ran fine and the codes were gone. I went for a test drive around the neighborhood and as soon as it hit 3rd gear it did the same thing as before. Today I put the old one back in and checked the codes so I could write them down and there weren't any so I went for a drive and it shifted through all the gears great and downshifted fine as well.
I pulled into my drive way to check for codes once again and there weren't any. I was gonna go for a ride in tow haul to see if it would do it and as soon I put the truck in reverse it started to idle high and the tow haul light started to flash again. I put it in drive to pull back into my drive way and it immediately shifted into 5th gear and threw the same codes...

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?

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.

Like the title says I'm having an issue the past few days where I can't drive this truck more than a few miles before it starts acting up with rough idle at stoplights/sign and sluggish acceleration until it gets over 1200+rpm.
Cold starts fine, drives good till engine warms up to around 130+ECT then it starts acting up. Stumbles on acceleration for little bit and puts out a little black smoke until it gets moving. No check engine light or codes found.
However a month ago I had the check engine light come on with a P0404 & P0405 and it still started & ran/drove great even towing. If I reset the code it would stay off until I restarted the engine the next time. I replaced the Dorman EGR because it had a lifetime warranty and only had 5,000 miles on the first one. The code did not go away until about two weeks ago the light went off on the dash and has never come back but I had not erased the code? So I'm not sure if this is still lingering issue or what.
I was checking my ScangaugeII when I came back home today while the engine was still idling rough and this what I saw for Numbers:
Low idle in Park
ECT 193
EOT 191
FICM 49.0
IPR 21.4
ICP 582
ICV 0.81
V 13.8
TFC 1.91
VSS(fan speed) 0
(This one doesn't seem right in the past is 500 or more rpm from what I remember?) What am I missing to check over?

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 .

My 06 currently has 296k miles. 3 years ago I put a lot into her. Dummy plugs, stand pipes, STC, hg,studs, oil cooler, bpd egr cooler. Cleaned spool valves and fresh o rings in injectors. (Alliant) plus a lot more that I can't remember. Ran very very well after all that.
Fast forward to a few weeks ago. Driving down road and truck died as I let off pedal to slow down for turn onto my road. Took about 7-8 tries to get started back up. Icp was reading in the 300's until it finally started. Made it home. Shut it off. And started right back up.
Few days later truck died again same way. Let off to make a turn. Several attempts to restart icp was in the 300's again. Once it started building 420ish it sounded like it was firing a few injectors and slowly started running. The next time it happened the same way but when I got it back running I eased to my inlaws like less than a mile. When I got to their house and pulled in and went to back up to turn around the display on dash said low oil pressure and started missing a little. So once I got home started researching.
A few days ago I pulled out the low pressure oil regulator to check it out. It was clean but did have some mild scaring. I used some fine scotch rite and smooth it out a a little. It moved freely in the bore so I put it back together. Then pulled the oil filter cap off to check the little black valve. I noticed the filter was not dripping with oil like normally when I change the oil. And yes it's motor craft filter and cap. It checked out ok. Press it down and turned engine over and it filled and held. Let off of it and it drained.
Next I air checked the high pressure side. Applied air and waited until I could hear the air (IPR still open) then closed the IPR. Couldn't hear any leaks. Just a very very minor his and couldn't pin point where. So I went ahead and went to dealer and got new stand pipes and plugs. And ordered new print set for injectors. Pulled injectors and didn't see any smoking guns. Replaced prongs, stand pipe and dummy plugs and put it all back together. Cleaned the injector cups and hold down bolt holes. Torqued injectors to spec.
Got it all done and rotate motor by wire next to heater blower to assist prime system. Tried to start it up and it took two tries but fired right up and sounded smooth as hell. After it idled a few minutes I saw a haze from exhaust. It smelt just like fuel. A few minutes later started idle a little rough. Gave it some go pedel and it was rougher at about 1600-1800rpms and couldn't feel it above 2k. Got my laptop out with AE and done balance test. Did not show anything. No codes either.
