You still should confirm your readings at the TPS. If you do not have an output voltage, it's not working and can still be the problem.

And just to make sure......you are leaving the the TPS connector plugged in the TPS when making your checks, right? Not meaning to insult you, just had to ask.

Still check the TPS by back probing using paperclips to ensure you are making good contact. It is very possible to get a bad part. Happened to me with the TPS on my 1992 Cherokee. It throws you, since it's natural to think that there's no way that the new part you just installed is bad. The car would start, if I started driving to work on the 40mph road near me, it would feel like it was trying to stall about a mile down the road, then pick back up and be fine the rest of the day. If I started it in the morning, and drove the residential 25 mph street, it would die......and seem like a no spark issue. After chasing my tail for a while, I finally replaced the TPS again, and problem solved. Disconnect the vacuum line to the EGR, plug the line with a golf tee (or the like). See if there is any change.

To ensure you are getting good contact, use some paperclips to back probe rather than trying to stuff your multimeter leads in. Ignoring the TPS for a moment.....do you still have an EGR valve installed?

In my 1992 Cherokee, it is mounted above driver's headlight, near the ECU and airbox intake.

Mine broke in 1992, when the truck was four years old.

That is exactly the same make and part number that I replaced my cat with. Fitment was no problem. I also replaced my front pipe, muffler and tailpipe at the same time. Did the entire exhaust.

Using the proper removal and installation tool...it's easy-peasy.

Disagree.... The grille, headlight bezels, and other front end pieces should not be the same as the body color. Mine didn't come like that. Something like that would look like a "(insert favorite cheap paint shop) Special".

Interesting..... Our son was born a year later on the same day as this was built. It did not come with a tachometer. Not sure what the head restraints are. No headrests.

Well, bingo. I have said that so many times. Virtually everything boils down to money.

Absolutely, Yes. I can vouch that the fan shroud does not come out in a simple manner.

Man, I thought that was a joke. Made me look. It's at 10 pages now.
