So my main full gauge has worked oddly since I bought the truck! When the top fuel gauge that measures the tank from 1/4 to empty says its empty which it is...the main fuel gauge says 1/2 tank..and when i fill the truck the needle goes as far as it will go past the full! and doesn't move until the actual fuel tank is half full! any ideas why this is happening and how I would go about fixing this!

Hmmm it has 31 splines? and the bolts that hold the hub on dont line up? As you can see with 31 splines, it says on the net that the 31 spline will fit from 89-93 and will not fit my 87..well you would call it an 86? What you think? -Nathan

So basically I bought some super winch manual locking hubs from napa and the box says its for a 1990 Nissan pathfinder! But when I went to put them on they were to big for the axle end with the splines! About 1/4 inch to 3/8" bigger, and the holes for the bolts are not lining up. They are also a little further apart then the stock bolts? Can anyone tell me why? or could it be that they put the wrong hubs in the wrong box? I just want to save the time, cause I will have to go into napa and get this fixed Thanks guys, -Nate

hey guys/gals, Sooo I go out the start the pathy and yet another issue. So whats happening now is I go to turn it over and it grabs for like 2 secs and ten lets go of the flywheel and all you hear is the zing from the starter! Im thinking the solenoid is screwy or the teeth on ether the starter or the flywheel are chewed up? And another thing I noticed is that the sensor right above the starter and beside the oil filter has 2 wires going to it but one of them is broken off the sensor? What sensor is this, the motors a v6 3.0L?! Thanks guys! -nate

yep I know what you mean man, you gotta do these things sometime, I had to do the same thing when I bought the pathy..The exhaust had more holes then then kISS in the 70's so I brought it in to a local muffler shop to get a full DP back exhaust! All because I didn't have my welder with me! Still got a good deal! but ya..still not getting much heat..its alright when the truck is right warmed up and the gauge is staying at the 1/4 so I will throw in the stat and see what happens and I guess I will focus on the lack of power and gas consumption! I will look into these sensors, check my codes again! and take readings from all and make sure there spec! Other then that, thanks guys! -Nate

Jeez man, thank god I've always done my own work. That makes me sick, what garages charge! Where I am the rate is 122.00/hr isn't that wild! Well thanks for the heads up..I will look into getting a sensor and just replacing it for the hell of it! Might as well give it a try! So, over to the heat issue. I ripped the ac box out and emptied the crap out of it, and there was nothing in the heat core box. But I felt the 2 metal hoses on the inside of the firewall that supply and send back out the coolant and they were nice and hot! but I put my hand on the heat core itself and was not anywhere close to the heat of the hoses! So my thought is that there is a good clog in the heat core! I'm just letting the truck cool off and Im gonna take off the return line from the outside of the firewall and run it into a jug and see if the flow is there. so I'll get back to you guys if that works! Anymore ideas? thanks, -Nate

So guys, I opened up the ac black box under the dash! and it was full of crap from mice..like leaves, insulation and pine cones..lol So I am thinking this is the same issue in the heater box right behind the center console of the dash, which means Im gonna have to rip the dash out and take both the ac and heater box's out to clean them? but yet I am getting pretty good air blown threw the vents just not good heat? Any suggestions before I finish taking the dash right out and if there is an easy way of getting the boxes out with-out taking the whole dash out would be helpful! That's a lot of outs! lol Oh and still even with-out the stat in, the temp gauge still gets up to the H and still doesn't blow hot air just warm??? Now would this nest effect the heat being blown ..I figured it would only effect the air flow being blown out the vents! but the air flow doesn't seem to be effected? Thanks guys!

Lol ya Im in Northern British Columbia! I moved here 2 years ago from southeastern Ontario..1hr away from Ottawa! But ya I am going to spend some time with this brawd today and see if I can get her heated! If she's like my woman wont take much lol

lol ya I meant TB injection...oops, but ya I think the choke you guys speak of is sounding like it could be the cause! as for the overheating I think it may be that the past owner put hard water in there and it cause lime build-up so Im gonna do the old vinegar trick and run it threw the system then flush it all out and see what ends up coming out! and throw a new stat in! Ya the block heater will be going in soon for now it has warmed up to -20 ish so its holding up..its when we get down to -30 to -45c that you have to start watching your battery has a blanket and there is a block heater ...even handy to throw in an inline lower rad hose heater! Where would this wax choke be located and how would I go about getting it fixed! I mean I will end up doing some research after I post this but..its helps to have a second opinion! and it doesn't run rich just when cold..its all the time and there is very little power going out? Yes I have checked the codes and it only gives me one and that's 44 ECCS Normal Operation so Im unsure what that means? My guess is that the computer is not sensing any issues..? Am I wrong? So you think if I pull the blower motor and fan that there my be a clog..but there is lots of air being blown threw the vents its just not throwing out hot air just cold-luke warm? I am thinking maybe the heater core could be clogged or the rad!! I am going to check the rad and heater core..any other ideas would be great! Oh and when I bought the truck I found some mouse droppings on the intake cover! So I am thinking them buggers may have something to do with all this!?? thanks guys for the input..keep er' coming! -Nate

hey guys, I guess you could say this is my introduction to the forum and all the great guys and gals that come together for one reason, Nissan and to help each other on there journey to mechanical success! My name is Nathan and I am a Nissan Owner, Of both a 240sx/aka Sil-80 with the Silvia front end Which is in the middle of a tear down and is getting built as we speak! and A 1987 Pathfinder which is also getting picked apart but still on the road. Just the main fix'r upper's that you want to get replaced when you don't know the history of the vehicle, and a few extra special things! Issue #1- So here is the issue, At first heat was great..warm as a mud hut in Africa! But now it sends the temp gauge way up and there is like a luke-warm blowing out now! So I went to replace the water pump..lol which as you know is a hell of a rip..but when I got down to it I found that the pump was fine so i figured I would bring the new pump back( ya i know I should have just put it in but I was short on cash and needed a alt belt) and took the thermostat out to run it with-out it! (dont worry my winters up when I live are in between the -20c and -50c range so Its all good for now! But ya it is staying in the 1/4 range on the temp gauge! and the heat is still luke-warm! which I can understand as there is not a real heat up for the coolant due to the missing thermostat lol! So I am waiting for my stat to come in and I will throw that in to see it that may fix it! and give me some much needed heat! Issue#2- When I wake up and go to start the truck, its about -26 lately in the mornings and the truck will turn over like 10-12 times..understandable due to weather and its a carb injection! but when it gets going I have to stay in the truck on the gas at about 3000rpm to get it kinda warmed up? and there is black smoke puffin out the pipe! after a few mins the black goes away and its normal white! which is normal here in Northern Canada in the winter!lol and when the truck is running it really sputters! and there is a lack of power like if you are driving a V6 and stomp on it it should get up and go ..this thing is like a slug! not much power at all Oh and its thirsty as stranded city slicker in the desert. 20bucks a day and we dont do a whole lot of driving??? And so these are my issues, I would really appreciate some input on these problems! Thanks guys! -Nate
