Hi guys, newbie here
I posted in the Jeep Buyers section but haven't received a reply yet so I'm trying here.
I'm looking at a 2000 Grand Cherokee Limited with the 4.7 and 115,000 miles on it. I will be inspecting the vehicle this weekend and would like to get some information before making an offer on it. I've been reading like mad on the forum here but have a few questions.
The buyer tells me that there's an ASD code and the Jeep doesn't start.
He has replaced:
I'm not sure if the sensors were Mopar parts or auto store parts.
He says that after the PCM was replaced the car ran for a little while but does not start again.
He also states that there's an ASD code and he pulled the relay and it appears the 87A socket in the fuse panel was missing the connector. I'm not sure what this means.
If the car ran briefly after the PCM was replaced, that would lead me to believe that the wiring to the PCM needs some work? Maybe there's a bad ground or a short somewhere? Or maybe the crank shaft position sensor was an auto store part and it has failed already?
I've been doing a lot of research on the forum here, and I'm a little confused. Can a transmission cause the car to not start and give ASD codes?
If all those parts have been replaced with good parts, does that narrow it down to the wiring somewhere? Maybe a bad connection to the PCM, maybe a short on the O2 sensors, something like that? Are the 2000's prone to the wiring harness rubbing on the stud, or was that only the 2003 models?
I should mention I'm not a mechanic, but I can do tune ups, brakes, change alternators, tie rods, do fluid changes, stuff like that, but I've never done anything inside an engine and I don't think I could swap a transmission myself. I also know how to use a digital multimeter, and I have a mechanic buddy with an 03 WJ that can lend me a hand and only charges me a friend rate for labor.
Thanks so much for the help!!
