Hey everyone, im new to third gen, so please bear with me. heres what i got. I did an engine swap on a 1992 camaro rs that had a v6 in it and i installed a 5.7L tpi from a 1988. The v8 came with the tranny the harness and the computer.installed everything but the car will not start. it wont even turn over. The fuel pump wont come on either. If i jump start the starter the engine will turn and if i run a hot wire to the fuel pump relay it will turn on. At first I thought it might be a vats problem but then i spoke to a guy at tpi parts and he said i would have to repin the harness to match the firewall circuits. I have no idea how to do this or where to find the info on how to do this. Will someone please help me out?? All input and info will be greatly appreciated. Thanks to All you chevy guys, keep those engines roaring and please help me get mine going.

This VATS tech article https://www.thirdgen.org/vats_passkey_system describes the system. Bypassing it is a matter of getting the power around the VATS pieces.

 

thank you, so do you think the problem im having is the vats system and i dont need to repin the harness and the firewall?
