    fuel reg on top of tank controls fuel psi
    the fuel pump should spin all the time with the motor running

    Sounds to me like you have a loose wire or connection..Especially after you installed a second one and its doing the same thing....

    im going to pull it apart again,
    all looked good to begin with and the old pump
    runs fine when i put 12 volts to it
    i have 12 volts to it when the key is in
    i was told ECU supplys the ground
    im thinking could this be were my trouble is?
    how can i test, ground pump directly?
