I have a 2002 1500 4x4 with a 5.9 . I know this is the second gen truck forum but being that they only used that engine for 1 year in the 3rd gen trucks I figured i'd ask here. last week it wouldnt start so we changed the dist cap,rotor, plugs,wires and finally changed the coil and it ran. drove it for 2 hours yesterday hauling my car trailer and it was fine. Today I went to move the truck and it stalled . When I tried to start it back up it was chugging like the timing was way off. Threw the code for the cam and crank sensors so we changed both. Still tries to start but wont. We checked the fuel pressure,spark,injector pulse, and even put it on tdc to check that the timing chain didnt jump.. all seems good. What wrong with it! Thanks for any help

 

Just so I understand the sequence, did you get P0320, P0340, and P1391?
Rechecked fuel pressure and spark and injector pulse after replacing cmp and ckp sensors?
Any other codes?

 

Just got the p1391 code. I just checked everything cause it wont run

 

Will your scanner read data? (do you have a scanner?) If so, check and see what temp the PCM thinks the engine is.

 

Yes i have an older snap on scanner that reads data. Says the water is 79 degrees now. It hasnt ran since yesterday morn and its about 85 to 90 degrees outside now

 

Pull a couple plugs, are they wet?

 

Yes the plugs are wet from fuel..you can smell it in the tail pipe. We put new plugs in and it still wont run

 

Try stomping the gas pedal to the floor, and holding it there while trying to start?

 

Done that a bunch

 

Well, you have gas, you have spark, we don't live in a vacuum, so, you should have air..... So, problem almost has to be too much, or too little, fuel.... Are you getting injector pulse? Getting spark AT the plugs?
