    1994 ford f150 won't switch to front gas tank from rear tank
    I have a 1994 ford f150 xl 4.9 straight v6 with dual gas tanks.
    When I try to switch over to the front tank from the rear tank the truck stalls out and won't start. Why is this and how can I fix this problem? <PS> even if I switch over before I even try starting the engine the truck still won't start.

    Does it die out right away or slowly boggs down and dies
    Fuel pump in tank or no power to it? The pump on the frame rail is high pressure pump and isn't able to SUCK the gas out of the tank, it has to get fead from the tank pump.
    They use the pump pressure to switch the tank valve also.

    I have a 92 f150 it now won't start. When I attempt to start it, I hear a clicking sound from the solenoid. I replaced the solenoid and there is still clicking and won't turn over. Put a new battery in and still not turning over... any suggestions on what it can be?
