        Resistance 

        TESTER CONNECTION SPECIFIED CONDITION TABLE

        Tester Connection Specified Condition
        3 - 4 Below 1 Ω
        3 - 5 10 kΩ or higher
        3 - 4 10 kΩ or higher (Apply battery voltage to terminals 1 and 2)
        3 - 5 Below 1 Ω (Apply battery voltage to terminals 1 and 2)

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