PGM-FI Main Relay: Description and Operation
The PGM-FI relay contains two separate relays. One is energized whenever the ignition is on which supplies battery voltage to the PCM, power to the
fuel injectors, and power for the second relay. The second relay is energized to supply power to the fuel pump for two seconds when the ignition is
switched ON (II), and when the engine is running.
