As a follow up to this post : https://www.cherokeeforum.com/f2/can...lock-me-56678/

Was having problems starting back up after Jeep was warm, would crank and crank, but no start. So I did another tune-up with new cap, rotor, and plugs. Plugs didn't look too bad, cap not too bad either, but figured was worth trying, since they are cheap.

Runs GREAT now. But since then, the key ignition switch has "freed up". Kinda stuck before like the tumbler was messing up, but could always turn it enough to get it to crank. Now it's rotating all the way forward like it should. Is there something other than fuel pump and starter that is controlled by how much movement the key switch has that would affect me getting spark or not?

I'm kind of all over the place on this...and just not sure what would have caused this issue to not start after warmed up. Hasn't happened yet since tune-up, so not even sure if the problem was corrected.
