INSPECT FUEL PUMP RESISTANCE



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

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

If the resistance is not as specified, replace the fuel pump and/or lead wire.


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.

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