Fuel Pump Relay: Description and Operation

DESCRIPTION 

The PGM-FI main relay actually contains two individual relays. This relay is located at the left side of the cowl. One relay is energized whenever
the ignition is on which supplies the battery voltage to the ECM, power to the fuel injectors and power for the second relay. The second relay is
energized for two seconds when the ignition is switched on and when the engine is running, to supply power to the fuel pump.
