Last night I experienced my jeep just turning off while I was driving. I started it back up and the engine was really rough then stalled again.
After this it wouldn't turn over at all. My buddy thinks the timing of the engine is off by a "tooth" I think it's possibly the fuel pump.
Anybody else have any assumptions?

Approx how much would a timing chain replacement cost with labor? Want to get a worse case scenario figured out just in case.

Thanks in advance guys,

Jay
