It would help if you provided a little more info on your truck such as what motor, tranny, etc.
Second, have you tested all fuses, both under hood and in cab? If not do so before proceeding.
If all fuses check good, have you checked for spark? If not do so now. You can do this by using an old spark plug that you know is still good. Remove one of the plug wires and connect it to that plug. Ensure you ground the metal threaded end by either placing the plug against some part of the motor. Or use a set of jumper cables using one end clamping the lower end of the plug and the other end to the motor block. Crank the motor while watching the plug to see if your getting any spark.
