Hey all. I am having trouble with my 2006 Liberty. I have looked all over for answers but can't find anything that fits my scenario and everything that I have tried from other threads has not worked. 2006 Jeep Liberty Sport 3.7L Automatic. Crank but no start scenario. It died while driving and would not restart. Cranked as normal but wouldn't even cough while cranking. I messed around with it for about a month and could never get any kind of life out of the engine. I replaced the crank sensor and the cam sensor, neither one fixed it. The scan tool is able to connect to the computer and read codes but when the scanner is connected to the vehicle no bus comes up on the odometer. The jeep shows no codes unless i unplug a sensor here or there and try to crank it. The code then shows up, can be read fine, and is able to be cleared with no issues. I did find that I am only able to read 0.01V on the 5V reference circuit with a volt meter. As a test I applied 5V across the reference circuit at the throttle position sensor with a 5v supply connected to the battery. The Jeep cranked about 6 revolutions and fired right up. I let it run for about 45 minutes with that supply voltage on the TPS connector and went to shut it off and disconnected the supply voltage first. The Jeep did not die when the supply voltage was removed which greatly surprised me. After that it started and ran, and even drove fine, for about 6 hours. Even was able to shut it off and restart it numerous times. I shut it off after driving it a couple miles and it sat for about 30 minutes before I went to restart it. It would not start again. I hooked the supply voltage back up to the TPS connector and it started right up. That was last night. It has sat for approximately 12 hours now but I just went to see what it would do and it started just fine on it's own twice back to back without the supply voltage applied to the TPS. Does anyone have any ideas on this? I have never seen a vehicle of any sort act like this and, to me at least, it seems so much different than any of the other crank/no start and no bus scenarios I have found elsewhere. Thank you in advance for any help that you may be able to give me. If there is any other information needed that I have not provided just let me know and I will try to provide it for you.
