90 buick lesabre electrical/starter issue

221K miles.  Late 2013 replaced starter and alternator.  Been sitting since mid 2014.  New
battery this week.  Put it in, dash lights came on, turned to start and weak click from
starter then dead.  Took battery back, had them test the next one (putting out 22 volts!)
and dropped it in.  

Now service engine, volts, temp and oil lights come on but when I turn to ignition nothing
at all happens.

Any suggestions on how to track down my issue?  I fear a blown fuse somewhere or a
cable chewed by a mouse or a dead starter but have no idea how to test for these things.  

Checked the fuse box under the dash (sub 25 amp fuses) and they are all fine.

The driver window leaks so if this is an issue for wet wiring or something I am disclosing.
