I've recently suffered thru this.... came out dash lights came on... CLICK then nothing.
I had just rebuilt my NSS.
Steps I took ( read and maybe you learn from my pain )
1. Read about dirty old starters ( mine had over 240K ) NOPE same thing.
2. Bought New Battery ( PO put in wrong size ), starter and both cables.
3. Installed new battery. NOPE same thing. Figured it was the old starter.
3. Installed new starter. NOPE same thing. Started to take back but with 240K worried about KARMA.
4. Disconnected the old cables. Left them in the plastic looms. Installed the new cables. Jepp started right up. Spent next hour taking out the old cables completely and installing the new ones properly.
My cables were the originals. After this I also went ahead and checked all the grounds.
My advise, based on this experience. If you think all the other items I have mentioned are good. Run a new cable down to the starter and give it a try.
Good Luck
