Fuel pump isn't running on my 91. (via ignition, which is fine). Pump runs fine when jumped directly to the battery.
What and where to look ??

Thanks for deciphering the wiring diagram Terry.I have the 90-95 wiring diagram. Fuse D powers the ignition, and the fuel pump. For power to reach the pump, after the fuse it it has to pass through the lean angle relay, which feeds to the kill switch and from there to the fuel cut relay.
As UP suggests, check for power at the fuel cut relay, and work back up the supply line. Of course the pump won't run with the kill switch off, and it will only run for a few seconds when you first turn the ignition on, and won't run continually until the engine is running.
The wire colors are called out in the link provided. There's two wires/pins for energizing the relay, and two wires/pins to switch the power to the pump. If you jumper the two pins in the socket to effectively bypass the relay and power the pump directly, you should have 12v at the pump. First thing to check is that you have 12v at the socket before bothering to put the jumper wire in. As Terry mentioned, there's other things in the path that could be causing the failure. So either start at the pump and work your way backwards, or start at the fuse and work forward.Thanks for that link Doug. I'll try what is suggested. (hopefully) . I do ok with mechanical stuff, but that electron stuff and lingo just completely goes through my head. I need basic how to's on what to connect to what.
