Nissan - 350z :: Gas Gauge Does Not Read Correctly / Rarely Shows Tank Full
Oct 29, 2012
I have a 2004 Nissan 350Z. During the first few years of the car, I always had a gas gauge that read correctly. Then, I had a recall notice about the gas tank. I took it in and got the part fixed. Now, my gas gauge does not read correctly. It rarely shows that it is full. In fact it looks like the needle "floats" up and down when I have driven it and used some of the gas.
Another thing I noticed is if the tank reads below 1/2 a tank and I go in to fill the tank, then start the car up, it looks like the needle just "sticks" and then jumps to almost full. I have put in some gas cleaners to see if that would work and it does a little but two things I would like to know:
If I decide to get this fixed, what is it that I should call this problem? When I mention it to the mechanics, they always act like I am nuts or they have never heard of this problem.

My gas gauge is intermittent. most of the time it reads right, but like 30% of the time it shows empty regardless of how full the tank is. What would cause this?

I just bought my 2012 Elantra Limited from the dealer today . The fuel gauge showed about two bars, a quarter tank I estimated. However when I went to fuel it, the pump clicked off after about 1 gallon, indicating the tank was full.
That was odd so I just figured there was some air in the tank or in the hose, so I tried adding some more fuel. I got about a half gallon more added when it clicked off again. Well, I know you're not supposed to top off the tank so I tried to add more. Got about two gallons added when it clicked off. I stopped fueling at that point for fear of causing damage.
My fuel gauge now shows a little less than half full. How can that be? Is there something I can do to fix this?

Been driving for 3 days now for a total of about 100 miles from a full tank averaging 50 miles per gallon. I noticed the gauge still shows FULL. Not even a bar below or something. Is there anything wrong with my gauge?

I recently bought a 2005 Ford F250 Super Duty, diesel 6.0.
As I was driving to work this morning I noticed that the fuel gauge read almost full when it should have only had a half tank. A little while later I heard a beep and saw that the gauge was now on empty with a "Low Fuel" message displayed. Then I noticed the heater was suddenly blowing cold air.
I've only had the truck for a few weeks, but haven't had any other problems. I did replace the CD receiver and all of the instrument cluster lights a couple weeks ago, but everything seemed to be working fine after.

I have a 2009 Prius. Yesterday, I had a very strange (to me) thing happen. My gas gauge read all notches, full. As expected, it went down a notch at about 120 miles.
I sat in a parking lot for a bit with the car in ready, running, and park. I noticed that whenever the car would switch to using gas, the gas gauge would change. It would suddenly show all notches again, instead of missing one.
When it would switch back to battery, the notch would move down again.
It eventually moved down 2 notches (which is probably accurate since I was sitting for about 30 minutes) and then would jump back up to full when it switched to gas again.

I been having this issue when I drive to 0 miles left on gauge, then fill it at gas station and it clicks like its full, but shows only 8.5-9 gallons? And fuel gauge shows 1 bar missing from full.
2011 66k miles
Took to dealer and they replaced gauge module and was ok for 2 fill ups but now its doing it again.

I had a fuel sender failure a couple of weeks ago. 60k mi.
Basically: freeway driving, fuel gauge read 1/8 tank remaining, computer indicated "10 miles till empty" but the car ran out of gas. Fuel sender, in the fuel tank turned out to be the malfunction.
Towed to the dealer...they had never, ever seen this before.
I get the car back next week, just want to bookmark this thread in case any members (God forbid) have this problem now or in the future.
I still have faith in my Lexus, but want to share as this failure was very unusual.

Here is my car info:
-------------------
1994 Ford Escort LX (Wagon)
1.9L SEFI engine
Just installed a new timing belt, water pump, thermostat and serpentine belt (the car was running great)
Here is the exact sequence of events that caused the issue:
----------------------------------------------------------
I was working on the car
I backed up on to wheel ramps so that I could check the exhaust
I noticed that the car was idling high, so I removed and lubed the IAC with WD-40
I put the IAC back in place with grey RTV and tightened it down ( It's not leaking at all )
Here are the exact symptoms:
-----------------------------
I turn on the ignition switch
The fuel pump pumps and sounds normal
The Fuel gauge shows about 3/4 tank (which is accurate... I recently filled the tank)
The low fuel light comes on (which makes no sense to me)
When I turn the ignition to the start position, the car cranks and sounds normal, but it doesn't even attempt to run. When I crank the car the Low Fuel light goes off, but the Fuel Cutoff light comes on (only while cranking). I also notice a slight smell of gasoline, but I can't find any fuel leaking or dripping anywhere!
What I've tried:
----------------
Looking for fuel leaks ( can't find any). Made sure the IAC is properly connected.
Verified and tested the Inertia switch in the right rear of the car ( it is working properly and has not been tripped). When I trip it, the fuel pump does not run. When I reset it the fuel pump works properly again.
Disconnected the + battery cable for 5 minutes or more in an attempt to reset the ECU. It didn't work. Symptoms remain the same.

I am working on this 99 Nissan and the issue is that the gauge shows the truck is over heating ,so we changed the thermostat ,the temp sending unit and that other thing next to that,and flushed the coolant system and bleed the system with new antifreeze and fresh water for the correct mixture..The truck still says its over heating ,the top hose hot and the bottom hose not anything more then it is when the truck hasn't been running.The truck starts right up and seems to run very well,then the gauge maxes right out and then wait for it to cool according to the temp gauge and drive a bit more,with in a mile its over heating again according to the gauge..I checked the oil and its perfectly fine and normal !I am so lost here,the radiator is like new and the clutch fan works right ,checked all the hoses and they are not collapsing ,water pump replaced a year ago...

I am thinking of buying a car but can't decide between a 2003 Nissan 350Z with 87000 miles on it, or a 2007 Mitsubishi Eclipse with 57000 miles on it. It will be a commuter car for me. I don't know a lot about Mitsubishis.

I am having problem with the gas gauge I have a full tank of gas but the gauge needle is stuck on E but when I unhook the battery and hook it back and start the car the gas gauge needle is on the full and its stays on full for like 3 days and then the gas gauge needle will drop back down to the E and stay there. This sound like something wrong in the fuel pump.

Full tank and the gauge reads empty. Has happened to me a few times. Occurs after a fillup and disappears after the car is left to sit for a while off. I would hate for this to happen on a long drive. Dealer hasn't been able to duplicate the issue. Am wondering if this might be related to the hiccup in some way. Also, am wondering if this is a fuse issue.

I'm new to the Gen 1.
All has been well in just over a month of driving the car and about 3300 miles logged. The 12v, Aux battery was dead from the car sitting on the lot for so long (I replaced with a new OEM Toyota 12v battery) After a week of the car experiencing dim headlights, and various other electronics
No codes or CEL though.
Now that the 12v battery has been replaced, the car runs exceptionally well, aside from an intermittent fuel gauge issue where it only reads full bars (completely full) if I let the tank get to empty (Flashing single bar) or close to that. If I fill the tank from s

So yesterday I was driving home from work.. I know my tank was 3/4 full. All of a sudden, my low fuel light came on and my gas gauge needle went to empty.
The needle sits at E, but it still says about 20 miles till empty on the MFD. When I left the house this morning, it said 5miles till empty.. by the time I got to work, it said 20. Kinda odd..
I will hook up the vagcom when I get home tonight, any area I should scan for? or just a complete scan? There is no CEL error on the dash though. What I could look at to fix this?

My car is in great condition. 70,000 miles and I am the second owner. Every time I take it to a mechanic they can't believe how good the engine looks. But there is a mystery problem. I have been dealing with what seems to be an air leak or pressure issues. After driving for a while the car has a lazy start after a stop. The first few gears seem to not catch. If fells like there is a block in a line and it's trying to push through air or fuel to get to the 3rd gear. I have noticed on colder days the timing belt screeches a bit. When in high altitudes this problem is worse! After my last oil change they noticed a leak. Also the dipstick for my transmission fluid is broken. Although I check it regularly and that seems to be just fine. I want to get to the bottom of this!

I was driving on the highway today, and when I turned onto the exit ramp and put the car in neutral I noticed my gear shifter shaking back and forth pretty violently. I looked down at the tachometer and saw it idling at less than 200 rpm's in neutral. I got to the light and my car stalled. I turned it back on and I had to feather the gas pedal just to keep the car running. I was able to make it to my local car mechanic with one foot on the gas pedal and my hand on the e-brake. It runs a little rough when in gear but at least it keeps the rpm's up enough to stay running. The check engine light never came on. My guy said that he didn't have the appropriate diagnostic machine, but he's afraid I might need a new throttle body and a new computer which may cost 1000's of dollars. I think the code he told me that he found was P0506. He sent me to a guy that deals only with Japanese cars, but they won't be able to look at my car until Monday.
Any thoughts? Hopefully something that doesn't cost 1000's of dollars. And if I replace the throttle body does that mean I have to replace the computer too? Is there something that I did or that I didn't do that I should have been doing that could have caused this to break?

Ok so the fuel gauge says empty and the low fuel light stays on even though the tank is full. I'm assuming its either the gauges or the sending unit. If it is the sending unit where is it located on this car?

My fuel gauge acted pretty weird today. When I left my house today it was just above half a tank. I was sitting in traffic quite a bit and then looked down and it was below the e. I knew it wasn't empty so I kept going. Got to work. Went for lunch and it said full drove about 5 mins to eat and it went down to half a tank. What's going on? I am thinking of the fuel sender or wiring?

As I was driving to work yesterday I noticed my fuel gauge going from half tank all the way to full going down the highway. I started looking at the rest and they seem to be in there normal spots. I looked up and watched the outside temp go from 40 degrees to 5. This morning the fuel gauge goes straight to full and the outside temp bounces between 2 degrees and 10. What may be going on to cause this?
The truck is a 2000 F350 crew cab with a 7.3 Power Stroke
