This is the original problem and has not changed. You can view this entire thread at www.jeepforum.com under the same title I used here. It is pretty sick. This site was recommended by one of the guys over there. I have also included the list of things tested and replaced along with the very last post. Thanks for your help.
O.K. here is the deal I have a 2000 Jeep Cherokee Sport 4x4 automatic that stalls after about 30minutes +/-. This goes back to earlier this year when it became hard to start. Come to findout it was the crankshaft sensor. Replaced and all was good. Then it started to act up again. 3months later. This time I had to have it towed, but I was near a parts shop so I borrowed their OBDII tester and it came up with crank or camshaft sensor. So, I bought the camshaft sensor this time replaced in the field. It started and died after giong around the parking lot one time. Called tow truck. At the shop they said the crank sensor went. They replaced it, I drove it one day and it died again. Back to the shop. This time they said the computer was dead. Jeep ended up back at my house after I got pi**ed-off at the shop for ordering the incorrect computer and letting two weeks go by without keeping me clued in on what happened. So, I have a car that dies after it warms up. It gets to just about 210 degrees and will shut-down. I have replaced all the above parts, switched the ASD relay with the cooling fan relay to no avail. I have checked all the connections and vaccuum lines. Nothing seems to be out of wack. It is now sitting on the others side of my neighborhood, after I test drove it today because it ran for more than 30minutes today. My mistake!!! Help me out. I want this car fixed, but I'm not sure where to go from here. Help me out. I'm not afraid to get my hands dirty, but I'm at a loss as to what to do next.
1. Crank Position Sensor replaced twice. The CPS has tested good
2. Cam Position Sensor replaced. Put the old one back with no change in problem
3. ECM(PCM) Replaced problem still happens Old or New
4. Removed and cleaned Throttle Body
5. Tested and replaced the TPS O.K.
6. Tested all 4 of the O2 sensors O.K.
7. Tested Coolant sensor O.K.
8. Tested MAT Sensor O.K.
9. Tested the Coil Rail at room temp O.K. Replaced with new
10. Tested and swapped the ASD Relay O.K. Replaced with new
11. Tested and Swapped Fuel Pump Relay O.K.
12. Cleaned went through every connection both electrical and vacuum found nothing obviously wrong
13. Tested fuel pressure replace fuel pump on recommendation of dealership
14. Replaced spark plugs
This is the continuing nightmare. I'm running out of ideas and the fustration now has me just about to the breaking point.
I replaced the ignition coil. Started and ran fine but died just as before. It only kicked up the 1391 code once since the coil replacement. It stalls while just sitting in the driveway with no codes or CEL. This is just too strange! I started it up and let it run while I disconnected sensors one at a time. Each sensor turned on the CEL and came up with a corresponding code that matched what I had just unplugged. The only exception to this rule was the IAC Motor; no code came up when it was disconnected. I know that the idle goes up and down as the A/C compressor comes on and off and I believe that the IAC Motor controls that idle function. So, with the IAC unhooked and the A/C on, the idle did not fluctuate when the compressor cycled. I plugged the IAC back in and the idle rose and fell with the A/C cycle. I guess that is normal. I also, took the time to remove the IAC Motor and give it another cleaning. The only other thing that may indicate that something is wrong was that when I unplugged the MAP Sensor the engine idle speed rose and fell and then stalled out in addition to turning on the CEL and sending up a code. Is that normal? Is there anything else that could cause this car to stall like this? It is slowly kicking my A**! I’m about to put a For Sale As Is on it and cut my loses.
