Hi,

Is your engine the 4.0L 6 cylinder or the 4.7L V8?

Expert:  Jared D replied 1 year ago.

Also, will the engine crank but not start, or does it not crank at all? If it cranks, it's not the anti-theft on this model.

should we try the crankshaft sensor
Expert:  Jared D replied 1 year ago.

The most likely cause is the crank position sensor. The only way to test it is with a lab scope, so I would just replace it and hope it works. Here is the procedure.
