I have a 97 4.0 zj that has a strange phenomenom going on starts fine till reaches normal operating temp. this is to say will start can shut of and start again and again. if you take for a drive run it till operting temp is met it runs fine no issues till you shut it off hten it wont restart no spark till it cools off thought could be a bad coil changed it no change in symptoms. knowing crank postiton sensors can cause lack of of intemediate spark failure changed out the cps still no change. now I am at a loss thinking the only other thing it could be is the cam sensor or better know on jeeps as pickup coil, but I have never seen one go out on a 4.0 dont want to just keep buing parts does anyone know if a cam sensor could cause the symptoms I am getting any ideas would be greatly appreciated.
