SOURCE: fuel gauge stuck on half full

I can tell you almost for certain your fuel level sending unit is bad, I have been able to fix them though. It requires removing the gas tank and then the fuel pump. You can if your inclined, bend the brushes on the small circuit board over more so they will make better contact on to it. Other wise its a new fuel pump assembly, check all plugs and wiring by unpluging and repluging them to insure no bad connect. It is possible it could be the guage itself, but in thirty years of fixing cars never had a bad guage

SOURCE: 2002 Chevy Suburban: Fuel gauge reads empty, tank is half full

Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.

SOURCE: 2001 Buick Lesabre - Fuel Gauge not showing correct reading.

sounds like you probably need a fuel level sender. it's located in the trunk on the right hand side attached to the fuel pump. I got one on ebay for about 20.00, but you might as well replace the fuel pump while you're at it, as it can go bad with time.

Fuel gauge consantly reeds half tank of fuel how do i test gauge and or sender unit


Sorry, but fuel pump and fuel gauge sending unit are all one unit, and in the tank.! There should be 2 straps that come off, drop the tank(preferably empty) and it's out.
NOTE* disconnect all fuel lines first and disconnect battery is a safe bet too.

Town and Country Van running out of gas and guage says half a tank what could be the problem?


If your fuel gauge is showing you in accurate readings this is normal to all vehicles that are not used to fill-up gas full regularly but sometimes the cause of the inacuracy is due to faulty float valve in the gas tank you need to replace it

Guages not working,


If all voltages checked ok,then most probably its faulty instrument cluster board on which gauges are connected.Yes if cluster circuit board looks ok,then also it can be faulty.Somewhere there is minute short or burn on board then such prolem arises.
Also check the fuse box.One under hood and other under dash.Inspect each and every fuse and see if all are fine or not.

My fuel gauge in my Benz- C220 have been showing fluctuating meter, eventually we dropped the tank and cleaned it up now it shows half tank when it is filled and fluctuates only downwards


I'm assuming this is a petrol car, and you can ignore the comments on fuel detergents if it's a diesel...because I know very little about diesel fuel characteristics.
It sounds as if one of the two fuel senders is stuck at its lowest level while the other one is operating OK. The sender windings can get coated in crud after quite a few years, particularly from fuels with low levels of detergents in them. That insulates the windings from the movable scraper that sends the voltage to the gauge, and leads to no readings or various stages of wrong readings.
Gently cleaning both units with carb cleaner should cure the problem. . The side with the petrol feed is a bit tricky and maybe the scraper in one of your senders got bent and stuck.

2004 Mercedes C-230. Fuel gauge stopped working. What's wrong? Mercedes says its a MAJOR problem needing some internal work. I doubt it! Please help. Thanks


Fuel float could be stuck, sensor could be bad... most likely it's not something major. On the other hand, it could require specialty tools or taking off major parts to get to the faulty equipment. A few things to check is if the 'low fuel' light comes on when your fuel levels are actually low. This would indicate that it is limited to an issue with the float and related items.
My Ford Escort had the same problem, fuel gauge was stuck at half tank for about 24 months. One day, in a near wreck incident, I ended up going over a curb, which must have jarred the fuel float back into action and it has worked consistently since. I DO NOT SUGGEST DOING SOMETHING RECKLESS WITH YOUR VEHICLE!
If you are comfortable using the trip-o-meter to gauge your fuel (take your fuel capacity and multiply by your lowest miles per gallon, and subtract 50 to get a good estimate on when you need to fill up... full every time) and want to save some money, it is no major issue, and may resolve itself. If you're intent on fixing it, ask a mechanic if he can give you a second opinion, and if you like his more, don't go to a mercedes dealership to get it worked on, a few well placed bangs with a wrench could fix it.

I have a 1986 190D Mercedes-Benz, the problem i'am having is i have to keep my car over half full of fuel in order for it to start right away. If its less than half full of fuel my car won't start right...


Check your fuel pump pressure. You can rent a fuel pressure gauge from autozone and check pressure coming from supply pump. I bet its weak. Hope this helps.
