    Does the fuel pump have power and ground signals to the connector?

    Can you year the pump running? Is there a plugged fuel filter between the pump and the carb?

    No I don't hear the fuel pump running. I pulled the fuel line apart before the fuel filter and no fuel.

    Then you don't have power or ground to the pump or the pump is bad.

    I found out what the problem was the green wire is the power supply to the fuel pump. On the passenger side under the rear bumper the wires going to the fuel pump where bad. Replaced wires runs great.
