I put a new sensor in.....lmao cant find my part number on my ECM no sticker on it anywhere does it have to be same part number or can it be from another jeep same as mine if it has to be same part number how can I find it lmfao will be last question I ask anyone
if your vehicle has a security system and you want to put a used one on it, the donor must also have security. same deal if you do not have security, the donor cant have security. if you get a refurbished one it doesnt matter.
if you cant get your replacement to work, please start a new thread. thanks and good luck
ZeeJay, It's MadDog again. I put on the Mopar CKPS today. No change. It's still lopping at idle, dying when giving it fuel, quitting just anytime it wants to. After changing all of the sensors, new PCM and new fuel pump and filter, do you think it could be a weak coil that fails whenever put under a load? All grounds are wire brushed and cleaned at all grounding points, All the fuses and relays have been cleaned and sanded, and checked to be good, battery terminals cleaned, all positive connections have been taken apart and wire brushed and cleaned. All of the 12 things to check, as per the list. The coil is the only thing left! When it dies, I can still coast, put it up in neutral, and it starts right back up, runs for a little while, then repeats the symptoms.
Brother, I AM STUMPED! I just love throwing money at this thing!. No codes coming up except 12&55
You've pretty much ran the gauntlet. If you haven't done so already, try to restore the tension on the PCM connectors and elongate the sockets on the coil connector so they make better contact. Coils can fail under load and they can be checked with a meter. There are some links you can follow in the ignition section.
ZeeJay, I figure why not at 231K? I've Replaced everything else that was OEM, There's always that chance I've been barking up the wrong tree the whole time! But, I swear, all the sensors, PCM, exhaust mods, fuel pump & filter I've done on this thing has shown to be a slight improvement each time over what I started with! I'll let you know how it comes out. It seems like now, All I've got is time to work on stuff.
Thanks Man! MadDog96
Well Zeejay, I guess in a moment of disgust, I have Let my temper override my logic. I have a nice chunk of change in this thing now and I'm still finding stuff wrong with it like all of the distributor terminals are loose in the cap, and you read my mind when you asked about restoring the PCM sockets, because when I got the new PCM, I just plugged it in, giving just a once over look at the sockets themselves. Every thing else is new, from front to back, either fuel or electrically related. My son's coming over tomorrow to put a new trans pan gasket on his 95, so I figure we can keep on studying the '96 until we get it right or decide to use it for parts. I guess I better run out and get some contact cleaner just to test the possibility of corroded sockets at the PCM. I've scoured this forum and corrosion seems to be the most problematic gremlin on most Jeeps. I've studied about restoring the sockets and it sounds rather intimidating with all those small wires, but if it can be done, I'm sure that It has by someone on this forum. Lots of good videos on here too, maybe I can search it out.
ZeeJay, I really appreciate your patience. Honest, I've read the Dirty Dozen, probably a dozen times or more. Every time I go over it, I find another item on the post that leads me to another probable cause of problems associated with this model of Jeep. Being a dyed in the wool enthusiast of Jeeps and the glitches that ensue, I can't give up on them, although at times it gets disgusting, especially this particular Jeep. I've even thought that maybe this one is a $30,000.00 factory original LEMON! Imagine that! I have now "Locked onto" the idea that I will get this one right, no matter what! I'll keep on plugging away at it. It has become a challenge to my psyche now. The most important thing I've learned is that there is no substitute for MOPAR parts when doing all this replacement stuff. I'll keep you posted as to any progress.
