no spark or injector signal for 5.3 i have a 87 monte carlo swap with a 07 5.3 gen 4 with dod, i have no signal from the pcm to the coils or injector but i do have 12v and ground getting to them, i am using the factory wiring with the factory modules? i checked all my ground and seen to be good? I am lost, i do not know if the alarm or key make make the pcm to short out the signal?
