I have a problem with my dodge ram 1500 2004 and it keeps cranking but it wont turn over and start and there is two codes popping up p0688 and p0129 if anyone can tell me the problem that would be great thanks

 

Same problem here except it won't even crank. Died on the highway, now no crank. It has P0688 and P2323, P2320 (and the same code for every other cylinder). I am assuming that the P23XX codes are BECAUSE of the ASD relay.

 

I have the same issue but mine just cranks changed out crank, cam, tps, MAP sensor, fuel pump and tank and replaced all relays but still no spark this truck has been sitting for a few years but was taken apart by pervious owner including some wiring have been spliced but now having wiring issues with some yellow with red stripe
