Fuel Pump Relay: Description and Operation
Fuel Pump Circuit
PURPOSE
Allows the ECM control over fuel pump operation.
Fuel Pump Relay Connector
LOCATION
In the fuse/relay center, in the engine compartment.
OPERATION
When ignition is switched "RUN" position (engine not running), ECM energizes fuel pump relay for two seconds, causing fuel pump to pressurize
fuel system. If ECM does not receive ignition reference pulses (engine cranking or running) within two seconds, it will de-energize relay, stopping
fuel pump.
After the engine starts, the ECM uses the signal from the electronic ignition module to determine if the engine is running. If the signal is
interrupted, the ECM will not energize the fuel pump. This prevents the fuel from operating when the engine is not running.
