How to Replace the Main Relay in a Honda CR-V

by Editorial Team

The Programmed Fuel Injection (PGM-FI) main relay in Honda CR-Vs manufactured between1997 and 2000 is located on the passenger's side behind the dashboard and glove box. This relay actually contains two relays within it--one that controls the power to the fuel injectors and a second relay that powers the fuel pump.

Step 1

Listen to the noises your Honda CR-V makes. If you can't hear the PGM-FI main relay clicking when you try to start up your vehicle, then your problem likely stems from the main relay.

Step 2

Disconnect the battery before working on any part of your Honda CR-V's electrical system. Electrical surges not only can damage surrounding parts, wires and systems and melt nearby plastic, but they also can cause serious shock or burns.

Step 3

Remove the glove box and passenger's dashboard lower cover. Pull on the right and left glove box stops that keep the box from falling all the way out of the dashboard, remove the bolts and then gently slide the box out of the dash. Remove the screws that hold the lower cover in place and push the top and bottom tabs to unclick the panel from the side.

Step 4

Locate the main relay toward the back of the dash and push aside or disconnect any wires, devices or other relays that block the main relay from view. Remember to note or diagram the original connections for future reference on a piece of paper.

Step 5

Unbolt any bolts that may hold the Honda CR-V's PGM-FI main relay in place and pull it gently from the relay socket without tugging on any wires.

Step 6

Replace the PGM-FI main relay, reconnect any disconnected devices, wiring and the battery. Test the ignition. If Honda CRV starts, reverse the order of Step 3 to put the glove box and dashboard cover back together.
