Fuel pump will only drop and gets stuck at a half tank. I can add fuel and gauge will go but as you use up gas will stop and stay one half. I have been reading a lot and an confused what to do and how to start. Also looked at owner manual and cannot find location of pump and whether or not my tank would have tone dropped to get to the bottom or if all could be done on the outside. Look forward to your help

It sounds like the level sensor has gone out. Here is a video that will show you how to replace it:

I was trying to point out is while I cannot get the gauge to go below the I can add gas and watch the needle go up to full. So while it is stuck trying to go below a half tank I can add gas and get the needle to go up. I am not stalling. The car runs good. Hope this helps. Thank you, Ed"

Sounds like the float for the fuel gauge is hanging up inside the tank. If your gauges normally go all the way down when you turn the ignition switch off, and that happens with the fuel gauge, you know that is okay and the problem has to be in the tank. If your gauges stay right where they were when you turn the ignition switch off, you will have to unplug the connector at the pump assembly. That should make the gauge go down when you turn the ignition switch back on.

Mechanics also have the ability to run all the gauges all the way up and all the way down with their scanners to test if they are functioning properly.

I have an idea your engine stalls once the gas tank becomes half empty. If that is right, suspect a dry-rotted rubber hose on the pump assembly. That allows it to draw up air instead of gas.

You can get to the pump by removing an access cover under the rear seat cushion. There's two clips at the front of the cushion.

Please let me know if you need anything else to get the problem fixed.

Best, Ken

If you hit the tank it may free it up, but I would be fitting a new sender then you know it will be correct.

We just replaced the fuel pump, was told it might be a ground, battery ground okay. Where are other grounds located?

If the fuel pump is working, the ground should be fine. They work from the same ground.

As far as the gauge, was there a new float and rheostat included with the fuel pump?

Hello. Recently my fuel gauge has stopped working (stuck on half). Shortly after I thought it was my fuel sending unit. So I bought a brand new one, and installed it. My fuel gauge still did not work after a full tank stuck on half way. Is it a fuse or the gauge?

Check for power at the FSU. If okay-could be the gauge is out of calibration.

My gas gauge is stuck on half a tank and will not move at all even when shut off or turned on. I have already replaced the fuel sending unit and checked fuses. I do not know what else to do.

Hello.

If you have already replaced the fuel level sensor unit and the issue remains the same then the wiring to the cluster gauge will need tested. Either the wiring or the fuel gauge/cluster itself is bad, so if the wiring all checks out okay than the gauge/cluster needs replaced.

Just bought this car used, as is, and noticed the fuel gauge is faulty. Gauge reads a bit past Full 90% of the time, but does fluctuate to empty and back every so often, so I know the needle is not stuck on the stop pin. The question is, what is the best way to repair/replace the fuel gauge, and can it be done without removing the instrument panel?

Thanks in advance for the help!

Suspect faulty fuel gauge sending unit. The sending unit, located in the fuel tank, is what tells the fuel gauge where the needle should be at.

Thanks! I guess that is a bit more involved than yanking out the instrument panel.

Yeah. If it were a newer model vehicle with the hi tech digital gadgets it would probably be simply replacing the instrument panel but then again that would cost a lot more as well.

I am going to assume that a sensor inside the fuel tank is not something for a "do-it-yourself" project, then? Probably best to send the bad boy out for this repair?

Unless you have experiencing with this type of work then, yes, I do suggest sending to a reputable repair shop. Anytime you are working around gasoline or any flammable liquid it makes the job that much more dangerous. So if you do not have the proper training then you could end up doing more damage to the vehicle and even worse you may harm yourself.

Find the wiring that goes to the tank unit (inside fuel tank) ground the yellow/brown wire while someone watches the gauge. If it does not move it is either a wiring problem from the dash or the gauge is bad.

To test it, you need a tester that can produce resistance, or two resistors of the values shown.

I have Toyota Gaia has fuel gauge just stops at half even if empty and if you top up gas moves up. What can be probable cause and solution to it?
