I have got a1994 gmc c1500 v6. An my son ran it hot an cracked a head. So I have replaced it an now that I have got it all back together it won't start. It has a new distributor an a new coil. Fuel pump is working fine. So I have decided to try a spark control module but I can not find it anywhere on my truck. I have the new one in hand. Does anybody have any idea where it would be?
