Off-Vehicle Inspection


FUEL PUMP INSPECTION

1. Inspect fuel pump resistance.





- Using an ohmmeter, measure the resistance between terminals 4 and 5.

Resistance: At 20°C (68°F): 0.1 - 3.0 Ohms

- If the resistance is not as specified, replace the fuel pump, lead wire or fuel pump bracket.

2. Inspect fuel pump operation.





- Connect a tester lead from terminal 4 of the connector to the positive (+) terminal of the battery; connect another tester lead from terminal 5 of the connector to the negative (-) terminal of the battery.

NOTICE: These tests must be done quickly (within 10 seconds) to prevent the coil from burning out.
- Keep the fuel pump as far away from the battery as possible.
- Always connect or disconnect at the battery.
- If operation is not as specified, replace the fuel pump, lead wire or fuel pump bracket.
