    Truck won't start but turns over
    1989 GMC k15, I got fuel flowing into the throttle body and it turns over and sounds like it wants to start but it won't.

    Control module? Check for spark.
    To run a motor needs three things,
    Fuel, spark at the correct time and air.
    You have fuel? So do you have spark at the correct time?

    Either no spark. I suggest try fuel relay or module power relay. If the fuel filter are dirty then it could be the pump.
