PGM-Fl Main Relay
Doscription
The PGM-Fl main relav actuallv contains two individual
rerays.
This relay is located at the lett 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 2 seconds when the
ignition is switched on, and when the engine is running,
to supply power to the fuel pump.
