Off-Vehicle Inspection

1. INSPECT FUEL PUMP RESISTANCE:





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

Resistance at 20° (68°F): 0.2 - 3.0 0hms

- If the resistance is not as specified, replace the fuel pump and/or lead wire.
2. INSPECT FUEL PUMP OPERATION:





- Connect the positive (+) lead from the battery to terminal 4 of the connector, and the negative (-) lead to terminal 5. Check that the fuel pump operates.

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 do the switching at the battery side.
- If operation is not as specified, replace the fuel pump and/or lead wire.
