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?
View 3 Repliesfuel gauge does what it wants? It goes down to half way then goes back to full or sometimes even empty. Not a big deal for me because I have gotten used to it. But I would hate to have my wife in here and she thinks it's good and run out.
View 14 RepliesI've been having a very erratic fuel gauge issue as of about 2 months ago. My fuel level would register full, when in fact I knew it only had 1/2 a tank or so. Then 5 minutes later it would be pegged on full. Under a 1/2 tank the gauge would read any where from 1/2 to empty from 1 minute to the next. So last week I decided to drop my tank and take a look. I was thinking maybe my fuel sender was broken, maybe a loose wire in the tank, or even that my float had dropped off in to the tank.
After dropping the tank, I removed the PK-Up and sending unit and everything was intact. I placed my ohm meter on the sending unit and it checked out fine. So I took the Pk-up and rolled back up underneath the truck and plugged it back in. I had my son turn the key on and off while I moved the float to different levels in order that it would register. It registered empty, 1/4/, 1/2, 3/4 and full just fine as I moved the float to those levels. If you leave the key in the run position and move the float, it won't register or better said, the in cab gauge will not adjust with the movement.
You have to turn the key off move the float and hold it there, then have your assistant turn the key on and the gauge will show the position that you've moved and held it at. I simply removed the plastic cover from the sending unit, and sprayed it down real good with electrical contact cleaner. I didn't scrub the copper contact area at all.
I was concerned that scrubbing might remove more than I wanted to, and really mess things up. I attached an Ohm meter and checked resistance thru out the float travel. All checked out good and I reinstalled it. So now my fuel gauge is working as it should be. I did make a video while I ohmed the Sender Unit thru it's travel, but for some reason it won't load.

The installation of the new 50 gal. Titan tank went well overall. Start up was smooth with no leaks but the fuel gauge is showing empty with about 45 gallons in the tank.
The sending unit was properly oriented ("clocked") so I'm guessing the electrical connector is not secure at the top of the sending unit. Not sure I can reach the connector without lowering the tank somewhat.
I have a 2004 F150 XLT 5.4 L 79,000 miles. Yesterday i was driving home turned a corner and the low fuel light came on and the fuel gauge is well below empty. I had approx 1/2 tank of fuel when it happened. I have since filled tank all the way but the gauge will not move and low fuel light stays on. Everything else is working fine! I have never run the truck low enough on fuel to make the dummy light come on.....
View 5 RepliesMy 01 sl2 wont start and the gauge says that the car is empty (before this problem, everything was working fine). I know that I have more than a half tank of gas, the car continuously turns over but wont start. I replaced the fuel pump and still it wont start (not to mention that the tank was more than half full at the time). I checked all the fuses and relays and everything seems fine. I am not even getting gas pumped to the filter.
View 9 RepliesFull 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.

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?
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?

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?
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?
View 4 RepliesI 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.
Fuel gauge goes back to empty when I fill the truck all the way up. It goes back to full once I have used up 2 gallons ( from 36 gal to 34 ) on my 2012 F350. I also had a similar issues years ago with my 2003 6.0L .....

Wife drove the truck before me and bunched the floor mat under the pedals. I didn't notice the mat issue when I drove the truck today. I accelerated fully after doing a left turn onto a busy highway. The motor spun up hard with the accelerator floored but because of the mats, the pedal stuck all the way down. I was approaching stopped traffic while under full acceleration and I shut the engine off and pulled over to the shoulder all while braking hard ( it was a hell of a ride!). I freed the pedal and restarted the engine.
Now, despite a bit less than 1/2 tank of fuel (I have the 38 gal tank), the dash readout was showing "Low Fuel", the gas gauge was below E and the engine was running like it was running out of fuel. I turned the engine off again and left it off for 1/2 hour before restarting it but the gauge and engine still behaved the same. As I drove to the nearest diesel station, the engine was not running "right". Of course the station I pulled into had 1 diesel pump and the pump was broken.
Because I thought I might actually be out of fuel, an understanding stranger took me to the store to buy some gas cans and then to another station to get 6 gallons of fuel. I got back to the truck and added the 6 gallons of fuel. When I turned the key on, the fuel gauge immediately came up to 1/2 tank. I then drove to that other station and added another 15 gallons of fuel to fill it. This confirmed that I had about 18 gallons of fuel in truck when the "Low fuel" warning occurred.
So, what the heck was going on with the fuel gauge? I am sure the "Low Fuel" warning is tied directly to the gauge but why was the gauge reading low? Is it possible that the "Key-off" while under full acceleration followed by hard braking had confused the ECU? I am just trying to figure out if I have a fuel sender problem or a confused computer that corrected itself. Until this incident, the fuel gauge has never been a problem but the wife messing up the mats has been an issue!
Its been happening often where it shows empty (when i really have half a tank) and my avg mpg resets itself. As I am driving it will go back to normal.
View 11 RepliesFor the second time in 6 weeks My 2004 F250 Powerstroke has run out of fuel with the gauge showing a 1/4 tank. First time it was just under a 1/4 showing I had it towed to dealer and they told me it had sucked in the filters requiring replace and flush of system. The told me that this happening very often and I would be replacing all of the injectors at my cost. I told them that I didn't want this to happen again and to check out the fuel gauge and sending unit and replace if in doubt. Well they checked it out and found nothing wrong, told me it was accurate and should not be an issue again. Now 6 weeks later on the Friday night before a holiday, it did it again, this time with over a 1/4 tank showing. I really don't want to spend 6 grand replacing injectors and would really like to trust my truck again, getting to the point that I'm nervous at 1/2 tank.
View 9 RepliesMy 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?
View 6 RepliesWhen my fuel gauge gets to 3/4s full it stops working and goes to empty. My range display also goes off. When I refill it works again until it reaches the same point.
View 5 RepliesI have an 03 f350 4x4 cc long bed and I seem to be having a problem with my fuel gauge. It doesn't show the true amount of what's in the tank and because of that I have run out of fuel a few times.
sometimes when I'm driving the light will come on and the gauge will drop all the way to empty then a little later it will go to almost full even with only putting 10 gals in the tank.
Any fix for this or do I need to replace the sending unit?
