        If the result is not as specified, replace the fuel suction with pump and gauge tube assembly.

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