TJ a no go please help

I have a 98 TJ 2.5L 5 speed that will not run doesn't even fire. Before it would fire up and run until warm then lose all power till it stalls out completely. I have changed the cam sensor and tried 3 crank sensor as well as the PCM throttle position sensor MAP sensor as well as many other parts and still no luck I've seen in places that on the 5 speeds the Cam sensor doesn't use the paper gasket? It has kicked a code saying that its not reading the Crank sensor which is why I've tried three now also is most recently kicking a code saying the Ignition/ Distribution speed is high thank you for you're time and help

Check all of the ground wires. I would remove them and clean them. Also check for continuity from the crankshaft position sensor to the PCM. The wiring could be corroded or broken.

If you are getting a crank sensor error, check the harness as well. Could have a wire rubbed through.
