PGM-FI Main Relay

The PGM-FI main relay contains two separate relays. One is energized whenever the ignition is ON (II) to supply battery voltage to the ECM, power to the fuel injectors, and power for the PGM-FI main relay (FUEL PUMP). The PGM-FI main relay (FUEL PUMP) is energized to supply power to the fuel pump for 2 seconds when the ignition is switched ON (II), and when the engine is running.
