On the rig not going into N or starting; check two things;
One, the stop fuse; if you don't have that signal, you'd have to use the park override to put into neutral or park to start it.

Check the neutral switch adjustment on the tranny. I imagine with all the snow ppl are busting thru right now that a few things might be getting knocked loose or out of alignment.

We've got the service manuals stickyd here for your use. That one for the 93 is suitable; just be aware there is 22RE and 3.sl0w info, so mind what you're looking at.
