1997 Sidekick - Starter does not spin

[Yuki]

Good juiced battery and terminals.
Tow truck and crew pushed and attempted bumping in 1st & 2nd gears engine spins but no spark?

Was working OK prior to no start / spin.

All lights, gauges, radio, work fine. The alarm bypass switch did not help.
At one point it clicked while I was pushing hard on the clutch?

How to start the diagnostics? Coil voltage?

Maybe the Clutch switch?

Additional - If I do resolve this issue I have another one, runs, If I fix this problem, idles fine, runs fine, but at a stop it dies when warm only, then it used to start right back up. Idle AIr control valve? I was getting ready to replace it prior to the no turnover issue. I would like to get it running and sell it for hopefully 2000 to 2300 - it was it really good condition.

Thank you
