Ok, ive got a 1993 Cherokee that has no spark and no fuel pressure.... would that mean pcm? The guy who had it before me painted it. I have found some grounds that had paint on them. Maybe a ground?? Ive jumped the fuel pump relay and wiring to pump is good. Ive unplugged the pcm and checked grounds. Good. What am i not doing? Also, ive swapped relays around and all seems to be all and well. PLEASE HELP!! Thanks.

Crank position sensor?

GIjoe

It turns over fine. So no. But i wish. Then my life would be easier. :-/

Muddog1981

It will still turn over if it's gone bad. It just won't send power/signal to the coil or ecu

GIjoe

And what about the no fuel pressure?

Muddog1981

Are you getting power to the fuel pump? If not then the ecu may not be telling it to work. Yet another side effect of a bad C.P.S. I only suggest this because I've had to replace a few myself.

GIjoe

I had to jump the relay to get the pump to go.

GIjoe

So no, its not getting power. I'll definitely look into it. Thanks!
