    First I am going to guess that you have a 6.0L engine. When you say you have no power to the starter I again am assuming you are not seeing battery positive at the “S” terminal on the starter and you already confirmed you have battery negative at the “B” terminal.

    Check the fuses, Neutral safety switch and the starter relay wiring.

    Here is a wiring diagram to help aid in tracing the wires.
