I have a 1995 Tahoe with an LM7 swap, and I'm trying to troubleshoot the fuel pump and I was wondering if anyone happens to have a schematic so I can troubleshoot the ignition switch, the fuel pump relay, and finally the fuel pump.
I have no idea how to troubleshoot without knowing which wire does what.
When I turn the key, the pump relay does not click. I need to test the ignition switch first but I need the pinout of the ignition switch. If anyone has any useful information it would be greatly appreciated.
