Main Relay (Computer/Fuel System): Description and Operation
PGM-FI Main RelayThe PGM-FI relay contains two separate relays. One is energized whenever the ignition is on which supplies battery voltage to the
ECM/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.
