Hello. Happy holidays my fellow ppl. So I bought a T/A 6speed without trans and I had auto on hand. I swapped the computer n harness. I Bypassed the vats got it cranking. No fuel pump prime, no spark. I changed the opti and new coil and new MAF. Still not getting power for spark. Is there something I can do to bypass something or whatever. Any advice and help needed. I did every other test fuel pump prime etc. not getting fuel pump prime and spark. Thanks in advance

Just in front of the ECM are two connectors. On the one closer to the engine you will find a single wire connector (pink if I remember right). Jump that to power, it's a fuel pump prime connector. Fuel pump should come on. If it does, VATS got you.

Mine is gray and yea it does prime. But I bypassed vats with resistor because it wasn’t cranking before. But I could be wrong I know nothing about lt1s
