99 TJ 4cyl auto will not start

Here's the deal... engine stalled as I was driving and when I restarted the jeep had a loud clicking noise that sped up when I accelerated. Drove it and then parked it, drove it again and stalled a quarter mile later and couldn't restart it.

Pulled the timing chain cover off and there was a plastic guide that was in two pieces. Belt was loose so it did need replacing. Sealed the cover and new belt up, still wouldn't start. From then on replaced distributer, rotor, plugs, wires, and camshaft position sensor. Gets the exhaust to pop a little more and still no start.

Compression is fine, signs pointed to the crankshaft position sensor, when I pulled the old one it had a round disc of metal stuck to it, any ideas on that piece of metal? When I put the new senor in, it would still not start. Both my dad and I are stumped. We can't see anything that it could be in the FSM either. Any help or similar situation help would be great, let me know if you want any more info to help determine the issue.

Rob

How loose was your timing chain? Is is possible that it jumped a tooth and now your timing is off? I kind of doubt it, but who knows...

Well we had guessed it jumped time, but we believe the timing is ok now that we've replaced the chain. We are trying to determine what the small round almost dime size piece of metal was that was attatched to the cks
