I hope I’m posting this in the right spot new to the site I had recently bought a 2004 cavalier with a 3.5 engine in it the pcm had gotten the wires ripped out of the connectors so I tried to re pin the connectors and if I sprayed starting fluid in the intake it would start but I could never get the injectors to pulse so after a few weeks of trying I decided to just start fresh and get another harness and wire it up still no injector pulse the pcm says it was from a 2003 Monte Carlo 3400 flashed to 3500 so the harness I got was from a 2003 Monte Carlo with the 3400 they had the harness piggybacked off the cavalier c100 and fuse box I looked up the serial numbers on the 3.5 block and it’s out of a 2006 Pontiac g6 does anyone have a wiring diagram for this similar set up or know what I’m doing wrong I feel like it’s gonna be something simple that I’m missing thank you
