    Angry Fuel Pump will not turn on?

    When i go to start the truck it cranks, and cranks, but not fire. I have a good battery, good spark, but no fuel is getting to the throttle boby. I have replaced the fuel pump, and all wiring inside the gas tank. The fuel pump will not turn on. I have also replaced the fuel fitler & the relay and no change. I am just not getting any power to the fuel pump.
    Any suggestions?

    get a wire diagram for your truck and a volt meter and chase down your porblem could be a split wire or something also check your fuses.

    agreed ^^^^^ you may need to drop the tank and check the coltage at the fuel pump, this should tell you if your getting any power to it

    i would definitely check your fuses first and then go through and check all your wiring to your pump.
