INSPECTION

1. INSPECT FUEL PUMP RESISTANCE





Using an ohmmeter, measure the resistance between the terminals.

Resistance: 0.2 - 3.0 Ohms at 20 °C (68 °F)

If the resistance is not as specified, replace the fuel pump.

2. INSPECT FUEL PUMP OPERATION
a. Connect the lead wire to the fuel pump.




b. Connect the positive (+) lead from the battery to terminal 1 of the connector, and the negative (-) lead to terminal 2. Check that the fuel pump operates.

NOTE:
- 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 switching at the battery side.

If operation is not as specified, replace the fuel pump and/or read wire.

c. Disconnect the lead wire to the fuel pump.
