Fuel Pump Relay

Fuel pump relay is located in fuse/relay block on left side of engine compartment, near battery. When ignition is turned on, fuel pump relay receives voltage from FI main relay. ECM grounds fuel pump relay, and power is then supplied to fuel pump.

Fuel pump will operate as long as engine is cranking or running and ECM is receiving ignition reference pulses. If no ignition references are received, ECM will shut off fuel pump.
