I drive down the road and it just randomly dies. Then I disconnect the battery sit a few mins reconnect and it fires right up. Anyone know what the issuses is?

 

Check your grounds, vacuum, spark, can you give any other details? Is it running fine? Any scanner codes?

 

Yeah when it runs it runs perfect. Just replaced the spark plugs. Does the CPS have anything to do with it?

 

Ill take it to advanced tomorrow and get them to hook up their scanner

 

Also I forgot to add it sometimes backfires.

 

80% CPS

 

X2..mine is doing the same thing (97 4.0, AW4) and I am waiting for one more Mopar sensor to arrive before I change them out. "Them" being crank,throttle,IAC and map. All Mopar parts because I have learned a lesson on AZ, AA and Ebay sensors. They just don't last and create havic and make me drink more...A LOT more!!

 

So would I be better off ordering the mopar part over what I can get from advanced?

 

Just got my jeep scanned its not throwing a code for the CPS. I only have 140K miles if that helps

 

I wouldn't count on it throwing a code for the cps, my 98 never did. Check your ohms and voltage at cps connection with a multi meter. The specs are in hayes/chiltons or online.

 

Checking it with a meter isn't a true test. They may check out fine but, still fail. I have learned that to the hard way.

I bought my crank sensor at moparonlineparts.com and paid $70ish with shipping. Not sure what a dealer would charge but, I have heard upwards of a couple hundred bucks. Yes, definitely go OEM than deal with Advance or the Zone. Trust me..

I checked out my old Ebay crank sensor yesterday and noticed that the insulation on the sensor end were cracked and showing the wires. That sensor was replaced last year.

 

bought mine from ebay original molar for 61 free shipping 3 month ago

 

Now its been sitting didn't start so disconnected battery let sit reconnected battery and started right up

 

every time you disconnect the battery, it fires right up because you are resetting the computer so it doesn't have codes to not let it fire.

 

Okay so ill just replace the cps and see what happens
