Hi guys.
I have had this problem for quiet a while.The jeep just turns off while driving withouth any reason.Sometimes if i pump gas fast it continues to run.it gives me the trouble code 11 (starter or fuel injector signal not received),first thing i need to do is change spark plugs,havent done that in a while over 80k on it,second thing depends on what advice u guys give to me.Hope someone will find time to answer. A 1000 thanks

Check your injector wiring harness for any open wires or shorts.. it sounds to me you might be seeing a short there shutting it down

That might be the reason coz long time ago i smelled burning and not once e very nesty smell where i could see the smoke,but i wondering why most of the time it works fine?
Another question ,there might be like tens of wires,how do i look for the burnt one? Sorry for the many questions.

It's allright. It is going to be a tedious process. But you are going to have to pull the whole loom apart and go though each one. There is 2 wires per injector. So there is not really that many.. but follow them back from the injectors. That sounds like it might be the source.

I tried to look around but couldnt see anything wrong but i will look again,and unfortunately i broke a valve that has to be taken from dealership which are open ony during weekdays.I have noticed something a few times.There is a strange noise (when the car turns off) like zzzzzzz but very soft.if i clear the codes it doesnt come and the car still doesnt turns on.Do u have anyidea of what might be the reason for the noise?
