Fuel Pump Relay: Description and Operation
OPERATION
When the ignition key is first turned to the "ON" position, the PCM will energize the fuel pump relay for two seconds. This increases fuel pressure
for cranking. If the engine is not running within two seconds, the PCM will shut off the relay and wait until the engine starts. As soon as the engine
is cranked, the PCM will energize the relay and power the fuel pump.
NOTE: The fuel pump relay may be bypassed by the oil pressure switch activating the fuel pump.
