1. Get a strong magnet
2. Use the magnet to move the needle into the top half of gage (don't take anything apart)
3. Test it by turning the car on.

Mine did the same thing. If you've tried starting it with a flat battery, the needle twitches and comes back up on the underside of the gauge rest pin. You have to remove the instrument cluster and slowly rotate it so the needle goes back to the top side. Its happened to me three times now.

The sending unit in the gas tank is probably shot. The fuel pump and sending unit is all in one unit. The gas tank has to be dropped to change it.

Could be a faulty fuel level sending unit or broke unit. And it's inside the fuel tank

It's your fuel sending unit. You DON'T have to drop your gas tank to do this. Remove the cover under your carpet on the right side of your trunk. It's right there, Unplug your wires disconnect your gas line, needlenose pliers work. Take a flat blade screwdriver tap the retaining ring off counter clockwise and pull your fuel pump out and replace the whole thing. use a sacrifcial towel to soak up the gas.This took me about 1/2 an hour in my car and im a flooring guy not a mechanic. SIMPLE JOB! fuelpump, ebay \$i25.00 parts store \$295 to \$340

The magnet trick works! I do mine a couple times every year when the gas guage goes under the peg. I use to take the cluster out of the dash and move it manually but I after reading about I use a powerful magnet.

The fuel gauge is not making contact with the sending unit in the fuel tank,or the fuel gauge sending unit in the fuel tank is bad.If this was at all helpful,please rate,thank you.

the fuel sending unit in the tank is a rheostat wrapped wire it increases the resistance read at the gauge the more fuel the more resistance.
what it sounds like is a dead short either in the sending unit or the wire running to it.
to check sending unit in the tank, locate the closest wiring harness plug (in the trunk/or under car) and disconnect then check gauge reading,remember ignition must be on.
try that and get back to me if needed

It sounds to me like you have a short in your wiring harness at you fuel tank. there is a plug on top of your fuel tank that controls you fuel pump and your sending unit that tells you how much fuel is in the tank. This plug can be a real p.i.a to get to on some vehicles, you may have to take the vehicle to a shop to fix it, if you are not mechanically inclined.

The gauge circuit is shunted on most cars, this is wierd, but needed to stabilize the readings... Your description sounds like normal function. Drivers would complain if the qauge were to be instant, going around corners, starting, stopping, all move fuel, and the gauge would indicate this, cauing driver alarm...Been this way for ever, although yours sounds like it is on the far side of the scale...if it reads correctly after a while, you could replace everything and you would have the same performance.

the float is likely stuck. try hitting tank with your hand with key on and it should pop loose, If not tank will have to be dropped

### My gas gauge is stuck on empty, how to fix

if your gas tank is empty of course the gauge is empty,but if the gas is full and the gauge still empty all you have to do is to check the float valve inside the gas tank maybe it is stuck.Or need to change if necessary.

### My gas gauge read that I had a quarter of a tank and about 2 minutes later it dropped down to empty

when it dropped to empty did it run out of gas or were you able to get to a gas station and put gas in,if so did the gauge read above empty.its possible that the float in the tank or the needle on the dash momentarily stuck for what ever reason and it may not happen again.

### My 1969 chevelle's gas gauge is stuck pass full.bad gauge or sending unit? how to tell?

According to what I read, test the gauge first. Hook power to where the white wire attaches. Hook a ground to the black wire connector. The gauge should rise to full. (May take a while). When on full, the tan wire connector to same ground. It should go to empty. If both work, gauge is good. To test sender, in the empty position, your ohm meter should read 0-2. 1/2 tank should read about 40, and full should read 84-88 ohms.

### Petrol gauge stuck on empty and light constantly

Sounds like a broken gas tank sensor in the gas tank. The sending unit has probably gone out.
