Re: 98 C1500 5.7L Fuel Pressure (Still Won't start)

At this point I am thinking the camshaft position sensor. Any other thoughts?

you have spark and the proper fuel pressure. spray some fuel in the intake to see if it starts. could be injector wiring /fuses /pcm wiring connector.

possible the timing is off/ spark at the wrong time.

the cps if n/g would provide no spark . with a good signal the PCM commands the spark at the correct time.

TDC rotor should point to #1 cylinder right ?
