Your post is correct . CPS & or fuel won't set the light . Most likely oil . Is the C Case full ?

CPS very much CAN set the light. It's not an "all or nothing" part. There's at least a code P0340 and P0344, both related to CPS faults. When a CPS is faulty, it may or may not run the engine, and it may or may not set a code. In any event, you're groping in the dark until you can get the code(s).

Update,the Diesel shop checked my truck and said I must have got water somehwere on the engine that wasnt suppose to get wet when I washed the engine off,as everything checks out fine and the truck starts right up now that its dry.The shop said they dont exactly what not to get wet on the engine,so I need some of you here on this site to give some info on what not to get water on and or things to cover.I know guys that wash there engines all the time and have no issues,also semi trucks get there engines cleaned regularly.
Please give me some advise here...

It was probably the IDM that got wet. It's the silver box on the inside of the driver's side fender. It has a vent that can let water in; sometimes it can even come in from the edge of the hood. You actually dodged a bullet getting it to start again; when the IDM gets wet, it seems to be about a 50/50 chance that you won't have to replace it.
