my truck died last night idling at the stoplight, sputter then nothing. i need help here, the guys on dmax forum aint helping, and i even resorted to powerstroke.org. well heres the story, the truck has had a bad seding unit for a few months now, reading a low fuel light and the fuel gauge on E. i know i needed fuel, so i went to start it outside my buds house, and it wouldnt start on the first crank, and thats odd it usually fires right up. fired it up drove about a half mile then it died at the light. no sputtering while driving, just sputtered for about 1/2 a sec at the light and cut out.figured i ran out of fuel, primed it through the filter and i had fuel. tried to start it.. nothing. cranks over but wont fire, kind of like when a crank sensor is bad. the CEL wasnt on while i was driving, but its on now when i turn the key. it threw a code and my buddys scanner couldnt decode it, you need gm software i guess, but it could be a prior code. all im asking is can the sending unit go completely bad? or can my FICM go bad? my CP3 and injectors are 10k miles old, right when i bought the truck they were already done with about 500 miles on em. i need help here, by someone whos a little more knowledgeable about these lb7s than me, its a BONE STOCK lb7 engine. i need this truck on the road as quick as possible, and im gonna change the sending unit, the fuel filter and get batteries (it needs it anyway) while im at it. please, any help is greatly appreciated. thanks in advance you guys here have always been pretty helpful
