i rebuild my 94 camaro m6 lt1 and the injector are not firing at all as a new opti and deltec i have lt1 edit i read the codes the only one i get is open fan 1 failure i try using a vat bypass and nothing i try a used pcm from ebay still nothing check wires to the pcm all was good. check schrader valve and push with a key and fuel shot out. put a volt meter to the injector and no pulse. is there any thing that could not be hook up that would cause this. thanks help is needed.

 

The injector should have 12v on the pink wire with key on and pulsing ground on the other side when they are firing.
