Just joined forums after lots of reading on here on my issues had with my 01 xj. Truck died on me couple weeks ago, stopped at store came back out, would crank but not start. Had fuel but no spark, from what i was reading most suggested it was almost always cps sensor, so bought one from jeep no luck. So ordered an ultragauge to pull codes, for p0340 which led me to check cam sensor.



Got new installed truck fired right up
Thanks to these wonderful forums for great information, hope it helps someone else.

 

Amazing! Good work mate, and thanks for the head's up.

Edit: I guess you'll have on to that original CPS as a back up.
