Gas gauge might need ajustment or re-placed. Won't hurt to get it checked out. Don't want to get stuck some where with no gas. Hope this helps.

SOURCE: gmc jimmy 1999, fuel gauge reading empty, even

the sending unit inside the tank has a open circuit that will not complete the signal to the dash gage. The tank will have to be dropped to replace this. The fuel pump is also a part of the sending unit. The part is not very cheap neither

SOURCE: Seems like it's not getting enough gas

It could be your fuel pump with your car not running right, the gas gauge thing i have no clue maybe the sensor inside the tank is messed up. or it could just be your fuel filter not doing its job. Htere are a few things it could be I would say Fuel Filter, Pump and maybe a vacume (spelling) problem, I would need to be there and hear it running or drive it to really figure out what it is

SOURCE: gas gauge always reads full, and then bounces from

This problem is only caused by one thing, and that is the gas gauge sending unit inside the gas tank is defective, it will need to be replaced to correct this. The gas tank must be removed from the truck to access the sender assembly.

How to adjust gas gauge to read right not reading way over filled like it does now. When 1997 chev 350 vortec truck gauge is at 1 st red mark close to empty, better not past gas station ! ! !

the fuel level sender is inside the fuel tank, part of the fuel pump assembly. did you or was the tank replaced before??they may have bent the float arm on reassembly . you can buy the sender from your parts supply store .you will have to drop the tank to do this it clips onto the side of the pump assembly. run it almost dry first as the tank is big n very heavy even 1/4 full. you can try to bend the old arm

but its very hard on the "sender" as for level indicator full to empty, think of the shape of the tank narrow at top to widest point in the middle (full to half) wide middle to narrow bottom( half to empty)

its just an overall volume thing

Put in new fuel pump and sending unit. but my gas gauge doesnt always work. sometimes is does and sometimes it doesnt

if it worked for a short period of time after doing the pump/sending unit the check the connections going to the pump/sending unit they would have been moved around doing the pump

Fuel gauge reads past full all the time

when the tank is full the resistance is low so the power through the gage make is read full
as the tank empties , the resistance increases so the less current means the gauge reads less until empty there is little or no power , the gauge reads empty
simple check , turn the ignition off, no power , no gauge reading

Gas gauge wont go past half it stops at half and will go to empty but never past half

There is a fuel gauge sensor in your fuel tank. If the sensor is out of place, it will not read the amount of gas in your tank correctly if it is out of place. This is a fixable job, but I recommend a ceritfied mechanic. Hope this helps! Please give 4 thumbs up!

Gas gauge

Sounds like you have a bare or broken wire earthing out on the chassis/body Trace the wires from the tank back to the engine bay and check that the wires are intact.
