    Fuel issue 2000 v6

    Hello, Trying to get my stang to start after sitting for a bit. Did a basic tune up. Car cranks but does not start. I tested the wiring harness to the fuel pump and two pins show no voltage. Is this normal? If so, good chance the fuel pump needs to be replaced? Thank You
