Fuel Guage wont work

[Boulder Cruiser]

I'm not sure if this is an electrical problem but thats what im thinkin. Any ideas why it doesn't work?
The gas tank doesn't have any damage. Its staying on empty with the gas light on.

[Alpine Spirit]

Not even a dent... Normally the tank has been hit when it stops. In that case the unit inside the tank needs to be replaced. Access panel is under the passenger rear seat.

There is a trail near Buena Vista called Old Chinamens Gulch... there is one rock there that has taken numerous gas tanks and resulted in the same issue.

[Boulder Cruiser]

Theres a custom skid plat covering the whole thing, I cant see any damage, but maybe im not looking hard enough. Ill keep looking.
I've been up to that trail a couple times in my old fj, didnt have any problems since the tank is under the passenger seat.

[ChefTyler]

I hate that rock...

You are the man!

I looked in the access panel and i noticed there was a tube that was unplugged (kinda hidden away) so i stuck it in, turned the X on and bang it works:bannana:
Now i just have to figure out why i can practically watch it go down.

You don't have any sort of codes at all? Not for the fuel tank issue, but for the mileage issue. Does it smell rich at all? Manual or auto? What gears are you running? Nissans are low geared from the gitgo, but with them thar tires, it might be geared too high!

I'd be interested to see if you have a knock sensor code at least. Dirty MAF, lazy O2 sensor(s) and whatnot could create a world of hurt at the gas station.

By the way, intake, what do you have there?

Its got d60 front and 10.25 rear 5.13's locked all the time, Automatic, doesnt smell rich. How do i get the "codes" do i need to go to a dealer or can i do it?

[bama16]

autozone will let you use theor OBD reader....it's free...that will give you codes of anything wrong.

OH :cool:
Ill do that in the mornin and let you guys now.

[Packman5280]

that axle combo is familiar, sounds the plushfab rig that had some, well, disappointing results. pretty sure that one was a 60/10.25 combo too.

[Allen Cox]

10.25"? Ford rear with a Ford D60 up front? Is the front a High Pinion like the newer Powerstrokes?

Looking at some of the Po's pics, it looked like it could wheel pretty well, but who knows ill just have to find out for myself. I don't know if this is a possibility but i wanted to see if i could put portals under it....at some point.

[Packman5280]

it wasn't that it couldn't wheel (the plushfab x, belonged to kinetic) it was that the spare tire mount broke off the exo cage, while the truck was being trailered! it looked like a 3 year old welded the cage. where did yours come from?

[Packman5280]

here is a thread from XOC detailing some of what went on with that whole deal.
http://www.xterraownersclub.com/cgi-local/ultimatebb.cgi?ubb=get_topic;f=20;t=009457

[Alpine Spirit]

Yep same rig but all the plush fab work was chopped and redone by a competent person.

I actually got banned from pirate4x4 for a couple weeks for warning everyone about the plush fab guy.

[Packman5280]

I don't understand that, i thought pirate was a little thicker skinned than that. maybe it's just the toy crew, sounds like MVM has them all wrapped up. usually pirate is ruthless on hack fabricators, perhaps put it in the chit-chat section.

[Boulder Cruiser]

Man that sucks! At least i know the PO fixed all that stuff. The PO was a really nice guy, Ive bought a lot of cars and he was the first to really go through and explain everything, and told me about all the little things that need fixing.
I don't know, i trust his work. Good to know, where the truck came from, thanks for the info guys.

I'm going to bring it to auto zone i a bit, do i need to tell them what codes i need or will it just give me all of them?

[Alpine Spirit]

Have em pull all the codes.

[Packman5280]

here is a thread from the PO on NOR
http://www.nissanoffroad.net/old_board/topic.asp?TOPIC_ID=21274&whichpage=1
looks like he bought it from Kinetic last summer.

couldn't find anything else from him about it, but I haven't looked too hard. I do think that all the bad work was removed/re-done, i remember seeing the cage tube in a pile in Kinetic's garage. I'm sure it will be fine, just kinda messed with my head for a bit, that the 1 ton x was in CO now. I doubt there is anything that can't be re-welded, if it needs it.

Just have them hook up the scanner to the OBD port and it will list any codes you have stored. Also, ask them to clear the codes, so if you go in again in a week you know that any codes are new.

[Boulder Cruiser]

Here is the link to the pics and builds ive seen...http://www.wesleycombs.com/
Thanks for the help guys ill be back in a bit with the codes.

[Packman5280]

ok, now I am really confused. the x that guy is building looks a lot like yours, but it is linked and coiled. what am I missing?

[Packman5280]

wow, so no more front leafs? didn't even realize that, saw the hangers are still there and assumed it was still SOA. So it is now a 3 link with coils. neat, i want to see it.

[Alpine Spirit]

Kenetic took it back from PLush
Kenetic sold it to Wesley Combs
Wesley then ripped it apart and redid it
Wesley then sold it to Boulder Cruiser

[Boulder Cruiser]

Yep that how it went. It is a three link with coils, the next step is a 4 link in the rear.
OK so these are the codes he wrote for me:
P0171 Too lean
P0325 Knock sensor
P0180 Fuel Temp
He also said something about my o2 sensor, I'm not sure if that falls into any of those but he said it needs to be replaced.
They didn't know what the "fuel temp" meant.

[Alpine Spirit]

Allen is the best with codes.

But I think sometimes the o2 sensor will show up but not actually need to be replaced. Normally after the knock sensor is replaced the o2 is fine.

[Boulder Cruiser]

So could this be why I'm getting such bad mpg's? :confused:

[Packman5280]

i would expect with a bad KS that you would be running rich, which would explain the bad mileage. not sure why you are running lean, but the o2 sensor could lead to that. don't worry about the KS, we can wire in some resistors that will trick the ECU into thinking the KS is OK, which will save you a few hundred bucks.

[Boulder Cruiser]

:bowdown: :bowdown: :bowdown: :bowdown: Sweet i feel a lot better now that i know whats going on. Packman (or anyone else) if you wanna come down and see it some time, just send me a pm. I don't know if you've noticed but im no mechanic, i know my way around a car and can figure most things out but help from someone who knows what there doing is always a plus.

[Alpine Spirit]

That is what we are here for... try to lend a hand and help each other out. There are some awesome people here with some INSANE knowledge of the Nissan innards. Now if only I could download all of it and put it in my head.

[CurleyMan]

Are you up for a carnage run this saturday? I think the guy (8th man) from virginia may have his sas finished on friday. I'm gonna run down to Allphase and try to convince vaughn and dave the 8th man should run carnage on sat... We will see what ever does happen i'm a rock junkie and I need my fix... So i'll be looking for a trail run this saturday

[CurleyMan]

And kev you should come down from the mountain to do some wheelin. I've never gone with ya it would be a sweet time to get warmed up for the summer...

[Alpine Spirit]

OK if you want some more information here is a TON. On knock sensor bypass.

KNOCK SENSOR INFORMATION (http://www.xterraownersclub.com/cgi-local/ultimatebb.cgi?ubb=print_topic;f=2;t=001042)

I may download it and upload it as a PDF for us.

[Boulder Cruiser]

I wish i could go this sat! I know this is going to sound ridiculous but its (Meghan) my girlfriends dogs birthday and i have to go to the party she is throwing for him....Yea i said dog :rolleyes: What can ya do!?! I might be able to wiggle my way out of it and join you guys

I may be able to on sun, I think Meg and i were planning on testing out the X on Mon or Tue next week, so if any of you guys are free next week let me know.

Come down from the MOUNTAIN!!! :laughing: Your Crazy!!!:rainfro:

Then everyone would realize what I really look like.

But Yeah I need to come down and hit Carnage. I may be helping Ryan on Thursday down at sidewinders.

[Packman5280]

I did the KS mod myself after reading a guys cardomain page where he scoped all the sensors in his maxima. he said a good functioning KS should read around 500KOhms to ground, so i just yanked the wire out of the sensor and attached 5 100KOhm resistors to it and hooked it to ground. no more KS code.

Sounds easy enough, ill give a shot.

[Packman5280]

yeah it is pretty easy. you can pick up a 6 pack of 100K resistors at radio shack for like a dollar, then wire them in line (one after the other). I wired mine parallel which didn't work, then in series which worked great. you can also just get one 470K resistor which I read somewhere that someone did and it worked too.

Ok great, i should be able to figure it out.

I hated the red on the X, so yesterday i rattle caned it all black. Here is the finished product and some poser shots.

I have a rule in my house that i cannot go wheelin without my Girlfriend. She works on sundays so I can't go this sunday sorry man..

No big, we'll figure somethin out, have fun on sat though. I think thats a very good rule, it will probably be enforced in my house as well :D

[zonianbrat]

Dude your X is awesome! What kind of MPG's are you getting? I would not think your gonna get very good mileage with those big arse tires.

Yea Gas....Not good, i got 5mpg's on the highway, some of my sensor's are messed up so once i fix those it should go up....Hopefully

Thank the lord you painted over that red. ;) I was to lazy to paint it.

Glad to see your wheeling it, once you get the rear linked make sure and re adjust the alignment on the front. Also when in 4wd are you getting a little axle vibration on the front? That bushing in the upperlink is rubber and I think it got pretty loose. I had some bushings custom made. They are about .005 larger than the diameter of the tube so they have to be pressed in. Give me your addy and I will mail them to you. (They need a hole drilled through the center for the bolt but that should be pretty easy if you have a buddy with a drill press).

I'm dying to get back on the trail. Hopefully this weekend in Harlan. :)

L8r man.
