Recently I have been having trouble starting my truck. I turn the key and nothing happens, not even a "DING" when the door is open. I figured out that the Ignition Switch Feed fuse, spot 102 and was a 20A, was blown. I replaced the fuse and turned the key and the instrument panel turned on but when I turned the key to the start position the fuse blew again. I was figuring its either a starter or a Ignition switch problem and possibly having a short in the line some where. Any input would be appreciated on figuring out what exactly could be wrong.
