Engine not running

Have the fuel pressure checked to rule out a failing fuel pump-start here

Youll need to check the fuel pressure.U say it starts right up but stalls.U need to know what the pump pressure is when it stalls.

Check battery for condition andhave tested at autoparts store. They do it for free. If battery is good check fuses an drelay underhood for starter. It can be neutral safety switch as well. Also befor removing battery have soemone help an dit the body of starter with hammer. If engine turns over tehn you probably have a bad starter. Then scan for codes and check fuelpressure, car doesn't need to start for that.

Hello,

This could be a problem with your vehicle's Auto Shut Down[ASD] relay, which is located in the Power Distribution Center in your vehicle's engine compartment. In the diagrams down below I have included a description of the circuit, location of the ASD relay, a guide on how to test the ASD relay, and a guide on how to remove and install the ASD relay for your vehicle. Please go through these guides and get back to us with what you find out. You will need to use a Digital Multi-meter[DMM] to use these guides, so here is a link to a guide below explaining how it's done:

Happy Holidays.

Hello and welcome to 2CarPros.

I've looked up your Jeep on AllData and AllData shows that there actually is a camshaft position sensor built in to the distributor. I'm attaching information on how to test the sensor as well as how to remove and install it. Please let us know what you find we'll go from there. Also, if this doesn't solve the problem for you, then please post the exact code number and, if possible, your VIN number so I can make sure that I'm looking at the right Jeep.

Did you go through the diagnostic process that I posted? Just because the scanner shows a code indicating a problem with the cam sensor circuit doesn't mean that the sensor is bad. It could be a wiring issue or anything else on the circuit. Hence the diagnostic process goes through checking all of it. Same thing with the IAC circuit. Getting 12v there instead of 5 tells me that there's either a short in the lead where it is contacting another wire that carries 12v or there's some sort of issue with the PCM.

Either way you have to go through the diagnostic processes.
