ok guys. Ive been searching the forum and putting off asking this for a while. I always figured I could find some information that would pertain exactly to my situation but it hasnt happened, now I cant drive my cherokee. anyway here is the problem... Here recently my truck has been suffering from an issue of random stalling, and long starts. It stalled for the first time the other day on a normal daily drive. at first I figured it was a simple one time glitch but ever since that one day it had stalled every time I drove it, usually multiple times in one day. So, I parked the truck figuring it to be a fuel pump issue but pressure was steady at 32 pounds w/ vac, 39 w/o. Ironically while I was testing pressure I accidently touched an electronic connector near the rear of the engine and just like that the engine died. It didnt stumble or miss It just died. Figuring it was a fluke I tried it again and again and everytime I messed with that connector the truck stalled. I have a haynes manual, and while not very helpful I did find out that the connector was comming from the CPS. I do know that when I touch the connector, it slightly moves the sensor on the bellhousing. I am wondering if my sensor is shot? I read somewhere on the board that a good sensor will put out about 125-175 ohms...mine is hovering right around 265-280ohms at idle. Now aside from that ohm measurement here are the symptoms my truck has. If anyone can tell me if they are indicators of a bad CPS please let me know...
1. long starts, usually 5 seconds or more.
2. quick stalling, no stumble or miss, just a sudden stop...like there is no spark
3. I notice that the engine dies when its up to operating temperature only.
if I do come to find out that it is a CPS malfunction how hard is it to replace? I am a fairly big guy so getting my hands to it looks like it will be a pain. thanks for the help.
