165 swap problems
Hey guys....
I just swapped an 89' ecm into my 85' z28. Now it won't start! I think it is a fuel issue as i do not hear the fuel pump priming
Sugestions? Although I did modify the prom, I think I eliminated the possibility that the ecm or the prom were bad when i plugged in an unmolested 87' ECM that was working when i pulled it out of its original car. Is there anything that problem could most likely be? if not... i guess Im gonna be weeding thru some wiring today

I followed those directions.... no fuel pump prime. I have even tried two different ecms. obviously somthing isnt hooked up right. I just need to know what part of the swap i would need to screw up in order to prevent the fuel pump from priming? How the 2 maf relays are hooked up wouldnt stop the pump from priming right? I just want to narrow down what it could be.... nothing on the list of repinnings appears to have much to do with the fuel pump.
