      1. Using an ohmmeter, measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        1 - 2 20°C (68°F) 0.2 to 3.0 Ω

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

    2. Check fuel pump operation.
      1. Apply auxiliary battery voltage to terminals 1 and 2. Check that the 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 auxiliary battery as possible.
        • Always switch the voltage on and off on the auxiliary battery side, not the fuel pump side.

        If the pump does not operate, replace the fuel pump.
