I connected a scan tool DB2 and low and behold the fuel pulse widths to injectors after normal engine temp, when restarted after 10 min, were wider in length for about 20 secís, then narrowed down thereafter resulting in smooth idle.
I think the problem is with the PCM.
#1057 of 1238 Jeep Ignition problem solved, Coil was bad
Jan 07, 2013 (12:04 pm)
Our 1997 Jeep Grand Cherokee Limited with 318 V8 engine died all of a sudden while backing up. We had diagnostic done on the car and it was found to have the original ignition coil in the car and there was evidence of CORROSION and WEAK OUTPUT of the coil, however the spark plugs were getting wet from my attempts to start the vehicle, so that proves that the fuel system was functional ............ We are replacing the coil at this moment and I will change out the spark plugs plus cap and rotor when I get the car back to my house. I recommend that you allow a good shop with electrical/ignition diagnostic capabilities to check out your Jeep if the engine quits like this .......... Of course could be cause any number of problem areas but with all the computers onboard and security system installed, you would be hard pressed to figure this out on your own.

I hope this is my problem, having the same issue. Stalls at light or stop soon after leaving home.

Have a similar issue but I have a clicking noise which now discovered is coming from the motor that controls the passenger side blend door. blend door seems fine but how would one get to and replace this motor which is behind heat assembly housing and between firewall.

It sounds like you need to check your fuel pressure when it dont want to start.
If your fuel pressure is readind what its supposed to , check your plungs and wires and if that looks good check your mass air flow.

I had the same problem. We thought it was the battery but after putting a new battery it wouldn't charge. We put a new alternator in and have had no problems with check gauge light or battery meter or any of it hope it helps. I hope it helps you.
