      1. Using an ohmmeter, measure the resistance between terminals 1 and 2.

        Standard resistance

        0.2 to 3.0 Ω at 20°C (68°F)

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

    2. Inspect the operation of the fuel pump assembly.
      1. Connect a battery positive (+) lead to terminal 1 of the connector, and a negative (-) lead to terminal 2. Check that the fuel pump assembly operates.
        NOTE:
        • These tests must be performed within 10 seconds to prevent the coil from burning out.
        • Keep the fuel pump assembly as far away from the battery as possible.
        • Always turn the voltage on and off on the battery side, not on the fuel pump assembly side.
