PGM-FI Main Relay: Description and Operation

DESCRIPTION 

The PGM-FI main relay actually contains two individual relays.
The relay is located behind the passenger's seat back panel.
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 2 seconds when the ignition is switched on, and when the engine is running which supplies power to the fuel
pump.
