Ok all heres my problem. I have a tpi setup running the vortec pcm. I have power and ground to the pcm. The thing is i have no signal to the fuel pump relay or the check engine light. I can ground both and they work. Also when the coil is hooked up the ign. control module gets hot and the coil shoots sparks. I tried a different coil and module. I also have tried a different pcm. I built the wiring harness from scratch. Also when touching the pcm housing with a test light it lights up. Dont know if its suppose to do that or not. Sorry for the novel, but i need to get this figured out. Thanks

Ok I figured out my problem. Just had 2 grounds in the wrong spot.
