        Standard resistance

        RESISTANCE REFERENCE

        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 the operation
      1. Apply battery voltage to both terminals. Check that the pump operates.
        NOTE:
        • These tests must be done quickly (in less than 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 the motor does not operate, replace the fuel pump.
