That should be a 4 wire relay. Use a test light to figure this out.2 wires should have power, one of the others goes to tehpump and the other to theECM (Ground signal). The other one should go to ground when engine is turned on (momentarily) then stay on when running. This vehicle uses an oil pressure switch to interrrupt the fuel pressure to prevent engine damage, so be sure that the oil pressure sender is plugged in and working properly as well. According to my wiring it has a fuse near the starter, but doesnt give an exact location.
