Alright I all of a sudden became a no start victim. The car begins to turn over and you can hear the engine engage and then shuts off. I had the battery checked and they are fine. I also added a ground between the engine and transmission as well as the alternator bracket and the engine. This worked for 2 days and now the jeep wont start again.

I am getting the following codes with the red lightening bolt:

P0652- Sensor Reference Voltage 2 Circuit Low

P0642-Sensor Reference Voltage 1 Circuit Low

Any help would help.

Thanks,

Dan

 

had this same problem intermittently however threw no codes for me. I had dealer fix what I suspected was a faulty park neutral safety switch or as Jeep calls it a (Transmission Range sensor) if you can get it started in neutral or by jiggling the shifter this is more than likely your problem. I had a similar problem before though when I accidentally pulled a fuse under the hood and put it back in the wrong spot.... good luck.
