Help i have issues with my truck

[krackerracing]

Thanks Guys
Fixed it!! I pulled the driverside valve cover and the harnes was starting to disconect.

YOu guys rock

I have a 2000 F250 with 125,000 on it. THe other day i was driving it and all of a sudden it lost all power and stalled. I started it back up and it ran like crap, like it was missing, it had no power. I changed the fuel filter and that didn't change anything. The check engine light cam on so i got it checked out but there where no codes. The next morning i started it and it ran fine for about 5 miles and then ran like carp again. Then i started it this morning again and it ran fine for about 3-4 miles and started acting up. please help.

Thanks
Eric

Check your oil.

Cam Position Sensor (cps). This is a common problem on 7.3s and they cost like $200 from the dealer or $50 on ebay for real oem ford ones. I ordered one off ebay to keep in my glove box. I believe I saw a deal on ebay that was 2 for $90 shipped. Buy this and keep the spare in the truck. There should be more experienced guys on here soon to back this up. Good luck

I had the same problem with mine. I took it to a shop and no codes came up. Then I took it to a dealer it turned out that I had a couple of Injectors going bad. I don't know why the first shop didn't see the code. Also did you just have you oil changed? I had wally world change my oil once and they put plain 10W 30 and it ran very rough. Much the same way that you discribed. Needless to say I change my own oil now.

i didn't think of that. makes sense....if you use foamy/crappy oil, it doesnt actuate the injectors properly and would cause the problems described. when it's cold and thick, the oil is fine. once the oil warms, if it isnt designed for the extreme heat and compression of a diesel engine, it breaks down and foams....then you got problems.

[payne5757]

He said "all of a sudden" meaning this was an instantaneous failure. Thats why Im thinking cps. It doesnt seem likely that the wrong oil breaking down fits the bill. Same with injectors, since this is off and on, it fits the symptoms of common cps failures.
