O.k.,it looks like your model has a fusible link in line leading from the starter to the main fuse panel.It sounds like this fusible link may have blown needing replaced.You will need to locate the gray wire leading from the starter to the fuse panel under hood and see if this wire is burned.You may have to tug on this wire to see if it stretches and breaks and if it does then it needs replaced with a new fusible link wire.It looks to be a 12 gauge wire.Below is the diagram of your main power feed of this fusible link.
