I have a 1995 Grand Cherokee with 160k.
I got home and turned off engine, 30 minutes later it wouldn't start. It just turns over but won't fire.
I get a spark when I put a wire near ground. I shot starting fluid down the throttle body, but didn't catch even once (I ruled out fuel pump due to that).
I was looking to replace the timing chain, as I thought it had jumped a tooth, but a mechanic said that was unlikely.
I am thinking Crank Position Sensor, or Cam Position Sensor - but didn't get any engine light warnings. Since I disconnected the battery to do work, I was told that any codes would have been lost.
Any help is appreciated. This is my primary vehicle.
