No spark ... stumped! looking for some insight here ... starting up car for the first time.
I've got fuel pressure
car cranks
VATS turned off
I've got no spark!!!
I've not checked to see if injectors are working though
I've checked all the power leads to the PCM, they all got power. There's 12V power at the injectors and the coil packs
I'm thinking it's either the crank/cam sensor, is there a way I can check it? Or is there anything else I should look into? really pissing me off.
Thanks

Thanks a bunch for your offer, but the car is in Balt. at the shop where I work. We have EFI live here but I haven't had the time to scan it, and still trying to figure out if there's an option to check the sensors. I'm guessing I've gotta get a GM scanner to check if they are.
The check engine light comes on when the ignition is turned on and all the guages work, so I'm still in doubt of the sensors
Put in a new cam sensor in today and tried again, no worky. I'm gonna see if I can replace everything external possible (like coil packs, etc) and keep trying.
My other option is to remove the wiring harness again and go through it with a fine toothed comb. The guy I sent it out to converted it using a 95 harness manual (even though I said it was a '94) so I had to make a couple changes when I got it, maybe there's something he didn't do right
