looking for 4.3l wiring diagram, 1997 gl motor.

[stang32]

picked up a real project boat, motor out and in pieces. wires cut, and replacement wires run outside of the harness. i got the engine together & installed & remarkable cranking from the key but no spark & no fuel pump. 1 wire in question is a purple one from the coil area. the coil wires are cut & spliced and there is no oil pressure switch/wiring so i know that is 1 red flag. so ,if anyone has a wiring diagram i can view, id appreciate it

I could be wrong but I have a 1998 4.3 GL and I think the purple wire is the the hot lead from the ignition switch that powers the ignition coil. I also think it enables the fuel pump relay to operate also. When the engine is cranking, the starter provides the power to the fuel pump. When the engine starts, the alternator is the fuel pump power supply. I think if you trace the purple wire from the ignition switch, it first goes to the emergency kill switch, then to the fuse panel. Dave-R
