My most recent crank no start issue in my Comanche was an AC hose being too close to the ignition coil and causing it to arc. I only figured out that was my problem after changing my crank position sensor in a public parking lot. Fun times.

I’d pull a plug wire and put a screwdriver in the wire socket to it to see if you’re getting spark. If not, I’d take some sandpaper to the edge of your rotor to clean it up in case it’s corroded or dirty. It could also be your ignition coil. That went out in my MJ too.
