Fuel pump relay
Hello my purchased a Ls harnes from a Buddy of his a few years back. Its a High Performance Injectors LS Standalone wiring harness. Probably a PSI knockoff. The problem we are having is that I'm not getting any power from the relay fuse block for the fuel pump. The instructions stated that I needed to run a contant power wire to the 30 terminal on the relay and a wire to the 87 terminal of the relay. Which it will supply power up the fuel pump. Not sure whats going on. I wired another friends truck with the same harness and it powered up just fine. I did notice that on his fuse block relay there was a extra white wire that was jumped over to the other relay. Someone added that wire. When they first added the LS engine to his truck. Attached are 2 pics that show the underside of my son's fuel relay block and my friends fuel relay block.
Thanks,
Ramiro
