I have a 98 ram 1500 4x4 5 spd. 318 /5.2 engine 240000 miles was running great went to work shut it off then restarted , then just died tried to re- start now just turns over and sorta trys to start,has spark to plugs(new) cap and rotor(new)can smell raw gas thinking timeing chain but no backfire thru manifold. any ideas please.Thanks Lee

 

Check fuel pressure with a gauge .

 

Ok Good thought all my other trucks are 1st gen diesels would not have thought of that thanks Lee

 

Ok I have 45psi for fuel pressure any other thoughts or am I still going to the timing chain?

 

Got spark and fuel, next, I would unscrew the precat o2 sensor from the pipe and see if it starts.

 

thanks will do Zman17

 

no go with o-2 removed

 

Are you getting injector pulse? Should be able to pick up a noid light at your local parts store.

 

Also, do you have a nice strong blue spark?

 

Getting injector pulse.It backfired once then never again,got spark thru plugs im workin outside by my self can see spark but can't tell if it is blue also have new coil on it but did not change wires.going nuts with this (some times I really love my diesel)
