I saw an article on how repair tripmeters recently, I just can't remember which vehicle (and therefore which forum) it was on. If anyone has an instrument cluster in the south Louisiana area for me to borrow, I'd like to take a look at it. My MJ is my daily right now and my backup currently has fuel problems.

Well was filling up in Alabama and my trip meter quit on me as I was leaving the fuel station. Anybody happen to have a write-up on how to repair it? If not it looks like I'll be tearing into my Dash blindly in the near future. Seriously this is how I feel some days. Sent from my SM-G930T using Tapatalk

Wipers have intermittently not worked since I've had the MJ, I think I finally figured it out. I've got chattering coming from under the dash here, I assume it's a failing relay or poor connection. Anyone know what I'm looking for? A pic of the relay would be helpful! Sent from my SM-G930T using Tapatalk

Yeah, I dated a girl in law school who studied that particular case. The actually dumped it in her lap as they handed it to her in the paper cup holder thingy. The woman was in her 80s and the coffee pot was set to 205 or 208 deg F. Those burn pictures are hard to forget..... Sent from my SM-G930T using Tapatalk

You're right, it doesn't. It doesn't have a lot of things. Like power, or a clock or even a passanger side mirror but worst of all.... no cup holders. If you drive an automatic, just hold it between ya legs!!!

This is exactly why I want to fully exo my MJ. Yeah rock climbing too, but really I just want to be able to Mad Max some genius who isn't paying attention.

Sometime in the mid to late 90s I believe this became required (along with 3rd brake lights....I bet your granada doesn't have one of those either). Every new car sold in the US has either an arrow or an indicator of some sort identifying for the poor young drivers of today where the "gas thingy" goes, along with a warning that it will give them cancer in Kommiefornia (ok, that last part I made up but it sure sounds good). Considering my '92 MJ is my newest vehicle of 8 other than my motorcycle and Mazdaspeed 3 (which is for sale)......I just have to remember. And yes, I too have pull up to the wrong side and stretched the hose over the trunk. $HlT happens....

Your buddy who made that front bumper.....have his contact info? I think I finally found one I like that holds a winch :D

I didn't install one on my truck. Works great without it.

X2. AEM makes the Uego, great quality wide band A/F tracker. Narrow band (like what your ecu uses) O2 sensors move rapidly making it hard to see what your fuel is doing. I happen to have the Uego installed in my MJ, used it to troubleshoot fuel problems I thought I was having. Sent from my SM-G930T using Tapatalk

Would posting the fuel injection wiring diagram break any rules? Since I have them, I figure I can share. Sent from my SM-G930T using Tapatalk

Found (and halfway repaired! )the issue. By some dumb stroke of luck I found a '92 jeep factory service manual and bought it. I used the included wiring diagram to TS my issue. Broken solder on the MAP 5V supply wire. So basically my MAP sensor was pulling down my ECU through the output line,and that's why the truck would die. Ohmed everything out using the diagram, tore open the wiring harness, found the break (at the solder joint), repaired break and started rewrapping everything. Oh and tested...the truck starts so much easier now! It's the purple and white wire, where it goes into the black heat shrink was the issue. Power comes from pin 6 (also supplies 5V to the TPS, that's why the solder joint exists). Considering I had issues with my TPS getting low voltage before, I'm going to guess this was part of, if not most of the issue all along. Another shot of the purple and white wire. The MAP sensor connector is green and on the left Sent from my SM-G930T using Tapatalk

New wrinkle. The second new MAP acted exactly the same as the previous one. So I back probed all 3 wires, just in case I had the wrong signal wire and found this. As soon as I plug-in the MAP sensor, the supply voltage drops from 5V to 0.5V. My first thought is bad connector possibly? I'm looking to see if I have a spare to test.

Damn. Run it for 500 miles or so to let the clutch "set", we used to have to do that (or ride it a bit in the parking lot) after clutch jobs. A lot of times that and a good bleed would fix a lot of issues.

Ruh row. Same issue. Reading 0.3V with power on. Unplug MAP, reads 0V (no feedback in line). Gonna swap this for another MAP I guess. Sent from my SM-G930T using Tapatalk

Awesome. Let everyone know how it turns out (issues, works fine, etc.)

You putting it in the truck soon? Sent from my SM-G930T using Tapatalk

Did you adjust the tps? The Renix motors have a small adjustment range that if you don't get right can cause issues. Sent from my SM-G930T using Tapatalk

I will give it a try. Thanks.Edit: Just to verify, you're saying yours started when you unplugged the MAP sensor? Yeah, although my setup is different being an OBD1. Started but ran real rough. If you have a multimeter and a paper clip you can check it properly. Sent from my SM-G930T using Tapatalk

Read through the whole thread and noone mentioned this but on my '92 I just had the MAP sensor fail. Caused a no start condition and I didn't have a CEL. Mine did run when I unplugged the MAP though (not great, and very rich). Possibly worth a try? http://troubleshootmyvehicle.com/jeep/4.0L/map-sensor-diagnostic-tests-1 Sent from my SM-G930T using Tapatalk

4.87VDC between MAP and negative terminal on battery. Getting a reading of .3 VDC on the signal side when the key is on. I disconnected the MAP and started the truck with my back probe in place. 0.3V. Connected the MAP and saw no change in value before it died. Repeated this but held the throttle mostly open and the motor kept running, still read .3V, died when I let off the throttle. I'm guessing it's reading too much vacuum? Either way I'm buying another sensor. This one is a Napa sensor less than a year old. Sent from my SM-G930T using Tapatalk

Will check when I get back. I know my TPS didn't like 4.8, when I cleaned up my ECU pins it came up to 4.94 and ran much better Sent from my SM-G930T using Tapatalk
