Two typical causes for this observation. First...the gauge (if it's an old analog device) may be faulty. Second...the sending unit inside the gas tank may be faulty. Based on your posting, I'd say your gauge is the problem. Simply replace the gauge. Unless it's in a modern Corvette where everything is integrated into the dash. Then...with great difficulty...replace the gauge.

SOURCE: 2002 Avalanche gas gauge problems

Gm has a real problem with fuel tank sending units. That is what is wrong. You need a fuel tank sending unit. You can only get them aftermarket with the whole fuel pump module, but you can buy them seperate if you buy it from the dealer.

SOURCE: Gas gauge is not reading correctly. Shows a full

the problem is caused by a defective gas gauge sending unit, this part is located inside the gas tank, you must remove the gas tank to replace it.

My 2010 Mazda 3 is showing full tank of gas when it's actually almost empty therefore it will not accept more gas.


If you cannot fill the tank because of an erroneous reading then it is time to replace the gas gauge sending unit responsible for the anomaly. Hope fully you can do it from the trunk - otherwise you will have to drop the gas tank to gain access.

Gas tank will not fill up on 2001 ford expedition


Gas as in gasoline or gas as in LPG gas? If its petrol, the fuel sender may be out of adjustment. (Usually means a new sender) If its LPG, the fuel stations are set to automatically shut off at 80% full. The gas tank will never actually be full to the brim but the gauge should be showing full if the gas nozzle keeps shutting off. Have a look on the LPG tank itself, they have a little gauge on them which shows how full it is. I have 2 tanks on my car , when "full" or when the pump shuts down, the tank gauges show just under full but the gauge on the cars dash shows full (2005 BA Ford)

The fuel gauge on my 01 caravan 2.4l reads full when running, and only reads 1/4 when off, any ideas what it could be?


Many cars do this to discourage gas theft. If the car fuel gauge only shows 1/4 full, a potential thief may not bother to steal 2 or 3 gallons of gas. This is very normal.

If the gauge is stuck on full and you are sure the tank isn't full, you have a sensor sending wrong information to the dash gauge. Most cars now have a single fuel pump and sending unit that can be replaced by a mechanic.

My 94 dodge spirit is overheating after only about driving 2 miles and there is coolant in radiator and reserve tank.. reserve tank fluid is hot and bubbling.. radiator fan may not be working


Does the temp gauge show overheat? If not, then you're not overheating. Possible you have a head gasket problem,which lets combustion gas into the water and can look like boilover.

Dash gas gauge stops showing proper gas level once it hits half a tank. Then gauge will fluctuate between empty (light will come on), full and anywhere in between but seems fine from full tank to half


If the trouble with the gauge started after you worked on it then you likely damaged or created a restriction to the movement of the sending unit. You will have to remove the tank and double-check your work.

How can i get to the fuel tank send unit only reads half full


well if you have it an empty fuel light came on to your dash, then you have travelled and just consumed the whole entire reserved gas in your tank, so when you are filling it up again, it will fill-up first the reservoir for your reserved gas then if it reach the minimum level of gas in your tank, then the fuel sensor unit will tell you now the exact amount of gas level on your gauge just keep filling it up (gas), DO not Press the entire trigger of the pump, just press it half way and moderate while filling -up gas so wont stop clicking and you thought that you have your tank full already but it was not.
