My JGC 6 cyl. was running fine for months after I bought it, suddenly while in red light simply stopped, started after aprox. 10 min, and stopped again at red light, got it back home. After that, every day I turn it on, runs at my garage for aprox. those 10 min and stops, not been able to restart for aprox a hour, took it to several dealershop, said it was the battery so I changed it, did not solve the problem, the manual codes came out 12 and 11; any help would be very apreciated.

Probably your crankshaft position sensor or related wiring. SJ

Thanks, Ill try checking it and replacing it, all right later here to say how it went.

I still have the same problem with my cuadratrac Jeep GC 1996, it still stops and wont start again after a few minutes. I changed the battery, replaced with new ones the crank and camshaft position sensors, changed sparkplugs and cables, but still is not running, any other posibilities!???? Help will be apreciated!!!:banghead:

Are you still getting an 11?

Sounds like either the Ignition Coil or Fuel Pump is overheating. When this happens again - Remove the gas cap, hold you ear close tot he filler hole and have someone turn the key to the ON position (without starting) and listen for the fuel pump to kick on (whirring sound).

If you can here the pump kick on the it is probably the Ignition Coil that is bad, when replacing the ignition coil I recommend replacing the plugs, wires, cap and rotor at the same time.

I am going to check the ignition coil today, and if bad will replace it also, I allready checked the fuel pump with a gauge, running fine, will write later if I get good news!!:runaround:
