Fuel Pump Relay: Description and Operation

PURPOSE
The fuel pump relay supplies current to the main pump, the in-tank pump, and the oxygen sensor heater element. The main function of the relay is to cut power to the fuel pump when the engine stalls.

LOCATION
Top center relay in the central relay panel. The relay panel is located behind the center console on the passenger side.

OPERATION
Battery voltage is supplied through fuse 31 to the relay. During cranking or running, the relay allows current to flow to the fuel pump and oxygen sensor. If the engine stalls, power is interrupted to both the pump and the sensor.
