Print
This relay is located behind the dashboard's lower cover. It consists of two individual relays. One is energized whenever the ignition is ON , thus supplying battery voltage to the Powertrain Control Module (PCM). This relay also supplies voltage to the fuel injectors, and power to the second relay. The second relay is energized for two seconds, when the engine is turned ON , to power the fuel pump.
See Figure 1
Fig. Fig. 1: Schematic of the PGM-FI relay
Testing
If the engine starts and continues to run, the PGM-FI relay is working and does not need to be replaced.
See Figure 2
