Brought my stalling Jeep 2006 (53,700 miles) into Jeep where they repaired the computer in 2006. Since then had loads of problems. Jeep running for twenty minutes when cooled down would start again. This has gone on for two years with jeeps comment; "We aren't getting this to stall". When they checked it out all seemed okay on the computer. Took it to get worked on (not Jeep) and they replaced the cam sensor and crank sensor then sent off the computer to be rebuilt ! Cost 350.00. They found 6 faults on the computer!!!!!!! The location of the computer was down below hoses to where leaks would affect the computer. Real close to the hoses from the radiator. What made the mechanic get the idea of rebuilding the computer was the ) meter reading that everything checked out okay. As I said they found 6 faults on the computer just placed in in 2006. The Jeep is running fine. Hasn't stalled once! Hope this helps? It has been a headache for two years and Jeep claiming everything fine. No lights on dash board, Jeep running. |

Replying to: volvoid (May 02, 2008 12:12 pm) If they are loose - do NOT OVERTIGHTEN! The studs are especially prone to snapping off & they all get 23 ft/lbs., if I recall correctly. (At least on my 4.0L.) I have the torque values etc on my site on this page: INTAKE ? EXHAUST MANIFOLD TORQUE VALUES & TIGHTENING SEQUENCE This page is for the older RENIX XJ's but other than some head port changes & HO exhausts not having the EGR tubing it should (SHOULD) be the same for all year 4.0L's. |

I have a 89 Jeep Cherokee Pioneer. I park it on the grass and in the morning it doesn't start. I just all the caps, plugs, wires, and filters changed out. It still won't start. When I come home mid-day it starts right up. What else could be the problem?

Replying to: neil693 (Jun 16, 2008 5:23 am) Next time it doesn't start up - lift the hood & unplug then replug the Crankshaft Position Sensor connector. (Back of head, driver side on US models, wire runs from harness to nearly hidden sensor on upper area of bell housing - diagram on my website.) Failing Crank sensors are a very, very common issue & often are intermittent until they finally crap out entirely. Connector is probably oxidized & morning moisture is causing enough extra resistance to prevent signal pulse from reaching computer. Give it a try & let us know how it goes. |
