The pump is grounded near the pump(black wire) to chassis. (Pink/black) wire goes to inertia switch then carries on (brown wire)to fuel pump relay. Relay is grounded from EEC module (electronic engine control) which gets it's signal's from ECU/PCM check wiring from EEC module (tan/light green) wire from relay to EEC module. (Red) wire from relay goes to fuel injectors
