1. Remove fuel pump relay.
-
Disconnect the fuel pump relay connector.
-
Remove the bolt and fuel pump relay.
2. Inspect fuel pump relay continuity.
-
Using an ohmmeter, check that there is continuity between terminals +B1 and FPR.
-
Check that there is continuity between terminals + B2 and FP.
-
Check that there is no continuity between terminals + B2 and PR.
-
If continuity is not as specified, replace the relay.
3. Inspect relay operation.
-
Apply battery voltage across terminals +B1 and FPR.
-
Using an ohmmeter, check that there is no continuity between the +B2 and FP.
-
Check that there is continuity between terminals +B2 and PR.
-
If operation is not as specified, replace the relay.
4. Reinstall fuel pump relay.
