This happened to me last year when i changed the starter. When I took it in the shop fixed it and this is the work order that I got for it.
1)check vehicle for no start
2)check wires going to starter
3)reroute wires so they wont touch the header
4)Replace fusible link
5)clean battery cables and terminals.
Im trying to figure out what the fusible link was. I've checked everything else that I can think of.
