I have an 89 jeep w/4.0 straight 6 that when it gets to 210 on the temp gauge it quits. It doesn't overheat but fan will not kick on.(Ele. fan) Then it will not start. I have waited a few hours then go to start again and it will start take it around the block and, it does it again. Has "new" Coil, distributior, Ignition Control mod. Coolant temp sensor in radiator. Spark plugs and wire. It still doesn't fix the problem. Any one please help.... ideas?
