engine stopped cranking
Alright, so I have had minimal problems with the car since my last post a few months ago, it has been running great. However today I drove it home, turned it off for maybe 10-15 minutes while I got ready for work. When I went out to start it again, I turned the key and it rotated maybe 3-4 times before it came to a grinding hault. I tried it again and the starter engages (thumps) but does not turn the motor. I then proceeded to push it up an incline and let it roll back down and pop the clutch, nothing. The wheels only locked up. I don't see what could possibly cause a seemingly healthy rotary engine to all of a sudden seize up like that. Checked oil and Coolant and they were still good (I had actually topped it off with oil when I filled up that morning). The car hasn't overheated, good oil pressure, and I am very meticulous about checking my gauges every few minutes. Does anyone have any idea on where to start tearing into this thing?

This is scary. I will be tearing into it at a shop tomorrow. I will try all these methods and a few others I saw on Atkins rotary. I will keep you guys posted.

Yes the pilot bearing is bad. It has made noise for a while now. Would a bad pilot bearing keep the engine from cranking even if the clutch was pushed in?

You should be able to turn the engine by hand with the trans in neutral. I seriously doubt the clutch or transmission is keeping the engine from turning.

Is there any possible way for the starter to jam itself into the flywheel? Because I was only cranking it to start when it seized, and it made a nasty grinding noise when it seized.

That's all I have at my home. XD
I have overhauled piston engines with just a jack, some jack stands and a creeper (and a lot of different of hand tools). However, this car is low and I now have access to the technology! Plus paying that much money for insurance with free towing makes me want to use it every once in a while.
