Fuel Pump Ballast Resistor Relay: Testing and Inspection
FUEL PUMP RELAY INSPECTION
1. Remove fuel pump relay.
(a) Disconnect the fuel pump relay connector.
(b) Remove the bolt and fuel pump relay.
2. Inspect relay continuity.
(a) Using an ohmmeter, check that there is continuity between terminals +B1 and FPR.
(b) Check that there is continuity between terminals + B2 and FP.
(c) Check that there is no continuity between terminals +B2 and PR.
If continuity is not as specified, replace the relay.
3. Inspect relay operation.
(a) Apply battery voltage across terminals +B1 and FPR.
(b) Using an ohmmeter, check that there is no continuity between the +B2 and FP.
(c) Check that there is continuity between terminals +82 and PR.
If operation is not as specified, replace the relay.
4. Reinstall fuel pump relay.
