I would be happy to help, but I need more information. First, does the starter engage and turn the engine? Second, is this a 5.4L V8 or the 4.6L V8?
If the starter isn't engaging, did you check the starter relay? Have you checked to see if there is power to the starter? I ask because there is a fusible link between the battery and starter relay that may have failed.
Take a look through this link and let me know if anything helps. It deals with the starter motor not working. If that isn't what is happening, let me know.
Also, I attached a pic of the wiring schematic for you to see.
Let me know.
