Ram won't run...
 

I have a 96 1500 4x4 318 Ram. Ive replaced crankshaft sensor, camshaft sensor, coil, throttle pos. sensor. it will not run, it is not showing any fault codes accept battery was disconnected. it was. it turns over fine, sometimes it will run rough for very short time but then it goes up about to 1500 rpm and dies

I will move this to the 2nd Gen (1994-2001) Ram section for ya.

Does it just crank and not start?

Check fuel pressure.

Yeah have you done the basic air, fuel, spark check?

wow you're in the same boat as me, i'm in pa also...about 30 min from hershey

i take it there is spark and fuel if it runs...but something is shutting it down
idle up doesn't make sense either....
key on engine off check fuel pressure at rail 45-50 psi
