Fuel Shut-off Solenoid Relay: Testing and Inspection

This test assumes vehicle does not run. If vehicle runs, refer to FUEL PRESSURE TEST for further testing.

Fig. 3 Fuel Cut-Off Relay Location:

1. With ignition off, remove underdash cover and pull down the fuse box/relay panel.

Fuel Cut-Off Relay Socket Identification:

2. Check for continuity between terminal 3 and ground.

Expected result:
Approx. 0 ohms. If OK continue. If not OK, a wiring related fault is indicated. Refer to CHASSIS ELECTRICAL DIAGRAMS for additional information.


3. Check for voltage between terminals 2 & 3 with ignition switch on.

Expected result:
Battery voltage. If OK continue. If not OK, a wiring related fault is indicated. Refer to CHASSIS ELECTRICAL DIAGRAMS for additional information.

4. Check for voltage between terminals 3 & 4 with ignition switch on.

Expected result:
Battery voltage. If OK continue. If not OK, a wiring related fault is indicated. Refer to CHASSIS ELECTRICAL DIAGRAMS for additional information.

5. With ignition off insert a jumper wire between terminals 1 & 2. Turn ignition on.

Expected result:
Fuel pump should run. If OK continue. If not OK refer to COMPONENT TESTING PROCEDURES for fuel pump testing procedures.


This test verifies circuit operation, if desired results are achieved fuel cut-off relay is defective and should be replaced.
