Need a wiring diagram for an 89 Firebird 305 TBI
Hello everyone. I'm having issues with my fuel pump not kicking on. I replaced the pump itself, as well as the relay with no luck. I noticed that 2 of the slots on the relay plug were slightly burnt, leading to the large black wire with a red stripe and the large red wire. Trying to find where those wires lead. Cannot find a wiring diagram. Thanks in advance

If you have a relay with a heavy black lead w/ red strip and a heavy red lead, I think you'll find you have the coolant fan relay. The fuel pump relay has about 5 leads going to it, from the top of my head, a dark green with white stripe, orange, grey, a red and I think a black. All pretty small in cable size.
Hope that helps
