I assume you mean the vehicle speed sensor on the side of the transmission? Which one are you replacing? The front one or the rear one?

 

checked my t-case fluid and it was a dark red so probably needs changing, could that be the cause of the grinding noise? the noise only started after the lift tho

also not sure how to remove the rear drive shaft and i dont want to do anything i can't put back together. any other suggestions?

 

Your logic is perfect. CPS can and will cause no spark.

 

That is correct, and his logic is correct but what are the odds that the fuel system and CPS died at the same time?

I just don't want him to go buy a new CPS and that not be the issue.

CPS doesn't control the fuel system...

I asked the OP if the fuel pump was priming at all. I don't think he ever answered me but... there's nothing else that controls the ignition system and fuel pump other than the CPU. I know he said he has no fuel but the way it was described made it sound like he was turning the key on and expecting the fuel pump to run constantly.

Perhaps it's the CPS and he just thinks he doesn't have fuel? I think a fuel psi gauge is needed.

 

Good to know. That was the response I got when I asked about my hybrid Xj with a GC 4.0. I apologize Paul O. Just trying to get your question answered pretty fast. Thanks Lowrange.

 

Just don't forget it won't fire if its flooded, and spray won't help. My little brother was always handy for checking spark....

 

lol Here, hold this.

 

PCM gives fuel when there's no signal from the CPS on these later Jeeps?

 

First make a line with paint or a wax crayon or something across the U joint, drive shaft, and pinion for alignment on reassembly.

Remove all four bolts on the two straps holding the U joint to the axle yoke. The DS will push forward slightly and the U joints will just pop out of the yoke.

Up at the transfer case end remove the metal straps (or zip ties) holding this rubber boot on:



Pull the drive shaft towards the rear of the Jeep and it will just pop off, exposing the slip yoke (yours will still have a steel debris shield on the shaft though, obscuring that oil seal):



Clean that up, grease the splines. Do the same to the female portion attached to the drive shaft. When reassembling you can use heavy duty zip ties to secure that grease boot. Don't forget to align the drive shaft, U joint, and pinion yoke according to that mark you made earlier.

 

awesome dude thanks a lot

 

Salad has some very good photos and is a pretty fart smeller to boot.

 

So the ole heeps check enginge light is on, been on like 2-3weeks, but it runs slick as a button. I got tired of seeing it so I swung by my uncles to pick up his Computer to scan it, but the "scanner port thingamabob" isn't getting power. What do I do? Im at a lose on this one.


Also what is the correct terminology for it?

 

Ladies and gentlemen, boys and girls!! After putting in a new CPS the jeep is now up and running and purring like a kitten! On top of that, my wife, children, the children's boyfriends and girlfriends and the neighbor's dog all think that I'm some sort of mechanical genius! Ironically, right before we left to purchase the CPS, my son's girlfriend was overheard asking my wife "Why doesn't Mr. Ray just take it to a shop and have it fixed?" Once again, this site and the invaluable advice from it's members have made me into the hero! Thanks to all of YOU! --- Once we located the CPS, (which was in plain view from above the driver's side of the engine on the edge of the transmission housing) it came out in 5 minutes and the new one went right back in. We turned the key to the on position and listened carefully for the buzzing of the fuel pump and there it was! We went to start it and the engine turned over immediately. (We were ready with some starting spray just in case but didn't need it it!) We took it out for a little spin and my son (the college student's who drives it) claimed that it was running much better than before; no doubt due to the new plugs along with that pesky CPS. Thanks again everyone!

 

^ Success story!

 

Glad we could help. Just remember though: you can go from Champ to Chump in a nano-second when family is involved.........
