Fuel Pump Relay: Description and Operation
The Fuel Pump Relay is housed within the Relay Control Module (1) located inside the Control Module Box (3) in the engine compartment. The Relay
Control Module also contains the Fuses (2) for the Fuel Pump Relay circuitry. The relays in the Relay Control Module cannot be adjusted or repaired. If
faulty or damaged, the entire module unit must be replaced as an assembly.
The Fuel Pump Relay supplies battery voltage to the Fuel Pump. The Fuel Pump Relay power circuit contains a fuse. The fuse is located in the Relay
Control Module. The PCM controls the Fuel Pump Relay by switching the ground path for the coil side of the relay on and off. The PCM turns the
ground path off when the ignition switch is in the OFF position. When the ignition switch is in the ON position, the PCM energizes the Fuel Pump. If the
Crankshaft Position Sensor does not detect engine rotation, the PCM de-energizes the relay.
