lq9 s10 Please help

Hey guys i need some help have a 95 s10 put a lq9 in it i have the pcm tac module and pedal. Iam trying to get the harness wires down. Iam powering my fuel pump up through the truck relay. When i try to start the truck it fires up then shuts down. Iam watch fuel pressure the hole time its fine. Iam not runnin fuel pump throgh the lq9 pcm. Heres my question without vats or passlock disabled will the motor run if i give it fuel through truck relay not lq9 ecm. Does the passlock or vats shut ignition down. Sorry no pics i have them on my computer but i cant get them to post to my thread

sorry forgot the motor is out of a 02 esacalade ext

VATS/Passlock will prevent the injectors from pulsing. So even if you have the fuel pump activated, it will not run for more than a few seconds (from priming pulse). You need the PCM reprogrammed. If you dont have someone local, pm us.
