The gas gauge on my 2001 Nissan Altima shows full when filled up, but only tets to 1/2 full when it is near empty. Suggestions?

It works, but it won't go all the way to empty. When it gets to 1/2 full, it need to be filled up. Checked all the fuses. They're good. Car runs well with good gas mileage, so it is not the fuel pump.

Either the fuel tank sender in the tank is bad and needs replacement, or the fuel gauge is faulty. I would bet the one in the tank is probably bad, because that's usually the case. Find the connection at the fuel tank, disconnect it and use a VOM to get a resistance reading while the tank is empty and reading 1/2. It should match the specs.

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.

The problem lies in the sending unit in the tank. It could have a wiring problem or the sending unit is bad.

2001 nissan altima with a stuck gas cap door. Lever in front ''seems'' to be working. But mechanism is not releasing. Best way to manually open it.

Open the trunk and behind the trim cover near the gas door only on the inside there is a cable pull there also. the owners manual will show you where it is it you have it.

Could be the float level in tank is disconected, or fuel gauge fuse is blown, or gauge itself is malfunctioned.

Take it back to where you had it serviced. They probably simply missed connecting the fuel level sensor. The engine light is probably from a missed emissions hose that goes to the gas tank.

01 s10 gas gauge goes either full or empty

Sounds to be a faulty tank sender unit, these senders use a fine coiled wire on which a brush slides along to vary its resistance.
If the coiled wire breaks midway, the only readings will be full or empty.
I think sender unit is mounted to internal fuel pump on this model (top of fuel tank)
Hope this helps, regards
