JamieXD Posted March 6, 2015 Share Posted March 6, 2015 Hey guys! So I just installed a new 8V voltage regulator on my gauge cluster as per the soultion2.pdf. My coolant temp gauge now seems to be working, but the fuel gauge is still inop. I'm suspecting the fuel sending unit is the culprit & after a quick search here it seems like that's pretty spot on. My question though, is what exactly am I looking for? I'm gonna check the wiring for loose connection, corrosion, voltage, etc. Just wanna see what you guys think. Thanks!

Pav Posted March 6, 2015 Share Posted March 6, 2015 If you are asking where to locate the Fuel Sending Unit...its attached to the fuel pump in the gas tank. Its not too difficult to get to. There is a trap door in the trunk area that you can open up to access it. Search around here on the forum I remember seeing a very good write up.

JamieXD Posted March 6, 2015 Author Share Posted March 6, 2015 I had seen someone mentioning a certain amount of Ohms to determine if the unit is bad or not. I was trying to find info in the FSM but no luck there. Link to comment Share on other sites More sharing options...
Pav Posted March 6, 2015 Share Posted March 6, 2015 From what I see its all outlined in the FSM - EL 58 - 59 for your model year. Link to comment Share on other sites More sharing options...
JamieXD Posted March 6, 2015 Author Share Posted March 6, 2015 Ah ok cool! I was looking in the fuel & ignition part. Thanks dude Link to comment Share on other sites More sharing options...
Pav Posted March 6, 2015 Share Posted March 6, 2015 No worries...hope this solves your problem. My money is on the fuel sending unit which is something you can do yourself if you are careful. Just keep in mind you are working next to an open fuel tank to get it out so all the normal spark and flame precautions apply. Link to comment Share on other sites More sharing options...
vagabond Posted March 7, 2015 Share Posted March 7, 2015 (edited) pull the carpet back and youll see the plate above the fuelpump/sender, be careful removing the fuel lines there may be pressure in them. if you need to completely remove it there is a multi plug inside of the rr tire area Edited March 7, 2015 by vagabond Link to comment Share on other sites More sharing options...

JamieXD Posted March 13, 2015 Author Share Posted March 13, 2015 (edited) So I haven't gotten a chance to check the FSU but when I took a quick glance under the rear of rig I found these loose wires. Driver rear Passenger rear Any ideas as to what they are for? Edited March 13, 2015 by JamieXD Link to comment Share on other sites More sharing options...
V8path Posted June 24, 2015 Share Posted June 24, 2015 I had seen someone mentioning a certain amount of Ohms to determine if the unit is bad or not. I was trying to find info in the FSM but no luck there. Does anyone know what the ohm resistance (empty/full range) is for the fuel sending units for the 87 - 95 Pathy's. Or where this info might be available? Link to comment Share on other sites More sharing options...
CO_pathfinder Posted June 24, 2015 Share Posted June 24, 2015 I have to ask, how did you not notice those wires before? In terms of your question, I'll check my rig/ FSM tomorrow to see if I can tell what those wires are for Link to comment Share on other sites More sharing options...
Terranovation Posted June 24, 2015 Share Posted June 24, 2015 I'd say he would have figured it out by now. Three months since he asked that question so I doubt he would have his Pathy sitting for 3 months doing nothing. 1 Link to comment Share on other sites More sharing options...

Totally did not even pay attention to the dates of the posts in the thread.. i still assume that its like the old days where a thread got 2 pages of posts in half a day..

CO_pathfinder Posted June 25, 2015 Share Posted June 25, 2015 (edited) Hey, I'm not saying that I had a pathfinder in the "old days," but that doesnt mean I wasnt one of the lurkers. My next door neighbor / best friend a couple of years older than me that had a blue two-door 90 back in 06, and we used this forum to do all kinds of stuff to it before safety inspection failure stole him from us But hey!!! Yesterday was the 1 year anniversary of me owning my truck so thats something!! Edited June 25, 2015 by CO_pathfinder Link to comment Share on other sites More sharing options...

Alkorahil Posted July 3, 2015 Share Posted July 3, 2015 Anyone have info re the ohm resistance for the stock fuel gauge? I don't have a Service Manual that goes back that far and cant find it in the archive. I can tell you on the 94 and 95 models the fuel sender unit is 1.5 ohms and the fuel gauge is 3.8-8.5 ohms full and 83.6-93.6 ohms empty. 1 Link to comment Share on other sites More sharing options...

With those numbers, they certainly made sure getting an after market fuel gauge sender is virtually non existent? Love my Pathfinder, but there's a reason to change things to a more universal parts availability when things need to be replaced or upgraded. Given the OEM tach and gas gauge is shot, I would likely be able to replace all the gauges for slightly more than what it would be to fix the existing stuff, and have all new instruments.
