If any of you have been reading about my son's '92 Jeep problems, here is an update. I will tell you everything that was done to get the thing running again. Yes, and we were about to light a match to it! :x
My husband did a complete tune-up on the Jeep because he experienced a constant miss at 2000 to 3000 RPM's. Then, the Jeep did not start one morning. He changed the M.A.P. sensor, the IAT Sensor, the Throttle Positioning Sensor (Jeep had been idling high), and the Crankshaft Positioning Sensor (Top Dead Center Sensor). These parts had never been changed.
The Jeep still would not crank, so he turned the distributor a little and got into the Jeep. It started, but still had a miss. When he turned it off, it would not re-start until he turned the distributor again. It only has about a quarter-inch play. The fuel injectors tested fine, and so did the compression after changing the head gasket set.
I had done some research and the last item on my list was the Cam Position Sensor a.k.a. Distributor Stator, or Pick Up Coil. I wondered why you would have to turn the distributor everytime you tried to fire it up?
I called two local auto parts stores, and they said that the '92 YJ did not have a Cam Position Sensor. It was not in the Chilton's manual, either. I was stumped...there had to be a type of sensor that would tell the distributor when to spark so that you would not have to mess with the distributor prior to firing it up. I called Jeep, and they found the part. I got the O.E. number and called the store back. They said they came up with Pick Up Coil after cross-referencing the O.E. number. YeeHawww! I believe that we will now be able to start up the Jeep without fondling the distributor, and this will also solve the "miss." The O2 sensor would not come off so that it could be replaced. It was badly rusted in place, so we ordered a new head-pipe that should be in tomorrow.
I want to thank everyone who has written in to the forums with their problems and solutions. I have been able to gain knowledge and remedy the problem. :D
Note: The Jeep has 150K miles on it. We have only put 40K on it since my son bought it three years ago. The timing is controlled by the ECU, so it should be fine. He should inspect the chain.
