broken down

I was out wheeling and all of a sudden my jeep died. I had just gotten half a tank then went to my favorite local trail, went up the trail and came back down and it just stalled out while I was rolling down the trail. I tried starting it, the starter was cranking but nothing. The odometer reads "no bus" and the fuel guage and battery guages are showing nothing. Any ideas? I figured its a fuel delivery problem, I checked the lines all are ok...:dunno:

Crank Position Sensor?

 

[wrenchead99]

methinks it sounds like a fried bcm, pcm, or wiring issue such as water intrusion or power supply problem. check the fuses. usually no bus means one of the modules is giving grief

I just stopped by the garage and they said the computer blew up. How much is a computer going to run me?

 

[TomH]

Same thing happened to me. On the trail about 15 miles from nowhere. IIRC the cost was about $550 for the module.

 

[JNickel101]

wow those things can just blow up????

 

[TomH]

Yeah, they're highly explosive.

 

[MG2000XJ]

It didnt actually "blow up" haha but you know what I mean.

Try a JY for a replacement. Keep to the same year though. I found one in a JY for $100. Good Luck!!

Found one out of a 2000 on ebay for 55 bucks. Is this a plug and play kind of component? Or does it require some sort of setup?

I would try the CPS Sensor, that same thing happend to my Jeep i purchased the computer which costs alot, i tried the cps sensor and it runs fine now.

[MG2000XJ]

Is cps the computer?

Crank Position Sensor. Located on the driveside of the bellhousing towards the top. Used to set engine timing and determine fuel delivery

 

[MG2000XJ]

I just talked to the garage and they said no fuel pump, no injector pulse and that they cant do anymore... They said have the stealership check out.

And the winners are... 2kxj, Jnickel, and 942wd! It ended up being the cps, the shop it was at ended up sending it to the dealership and I should have it back today if there are no other problems. Thanks for all your help guys!

I was gonna say CPS too, but I once had the coil wire come off my XJ on a trail ride, no idea how. After a few minutes of scratching our heads it was spotted & fixed, no problems since.

Is a replacing a cps something hard to do on your own?
