Question about 2006 Isuzu Ascender

The gas gauge does not work

I replaced the fuel pump two years ago and now the float isn't gauging the amount of gas in the tank. Is there a relay or sensor that may be causing the problem? The fuel pump is working fine but the float is integrated in the pump. Any solutions to the problem without replacing the pump again?

SOURCE: Fuel Gauge reads empty, but tank IS full

the float in your gas tank seems to have water in it....water is heavier than gas, that's why gas floats on top of water....try putting something like HEAT in it to dry up the water in your tank....

SOURCE: I have a 2005 Saturn Relay. Everytime we fill-up

Some of these GM's have a seperate fuel guage relay under the dash. Their not cheap. Since you could have anything from a bad sender in the tank to a bad relay its best to leave this to a professional. Next time this happens try smacking the fuel tank a few times hard. If the gauge goes up its most likely a sender in the tank issue. If nothing happens then it really needs to be diagnosed correctly.

Bad sending unit attached to fuelpump or most likely a crimped or chaffed wire to it, either inside the tank or outside.

I changed fuel pump. Now the gas gauge does not work


year/make/model?? Does the gas gauge read empty or hard full? If it reads hard full, suspect a ground problem at tank. If gauge doesn't work at all, make sure there is power to the plug at the tank. It is also possible the float arm may have become disconnected as some of these units are tight to get back in the tank. I have also seen new pump/gauge assemblies with defective sending units resulting in non working fuel gauges.

When truck is in motion going down the road gauge is all over from empty to full when stoped it reads properly


Your gas tank has a float inside that is kart if tne. Fuel. Pump assembly that indicates the amount of fuel in the tank..it sends a message to the gauge...sounds like the float is sticking when the gas is sloshing around when moving..causing a false read being sent to the gauge. Most times the tank has to be removed to replace..good luck..

Replaced fuel pump now fuel gauge isn't working


sending units get knocked out of calibration when they change the pump.(carelessly).if you can.. check the top of the tank, to see if they plugged it in firmly. if not, raise heck till the change it. (doubt they will). other than the wires, not much you can do, without dropping the tank.

Why is gas gauge not working correctly since fuelpump was replaced.


Is this a flex fuel vehicle. If so, call the dealership and ask the parts dept. if there is a gauge module (perhaps behind the instrument cluster). This may be the culprit and needs to be replaced.

2004 nissan sentra have problem pumping gas


When you're pumping gas, does it stop you at the end, when the tank is nearly full, or is it not letting you pump gas at all? And how does the fuel gauge read after you've added gas? If it stops you and it still says the tank isn't full, it could just be that the float in your tank that connects to the gauge is wrong.

Is there a relay for the gas gauge on a 1995 ford contour


Normally no. The fuel gauge reads by resistance, the position of the float in the fuel tank, that voltage is directly sent to the gauge. There is also usually a warning light that operates off of this same system but it reports when the float level is extremely low only.

If the gauge isn't working, you may want to inspect the wiring harness at the fuel tank to make sure everything is intact, nothing frayed, pulled loose, or broken under there. If the pump has been replaced, sometimes the fuel float gets into a bind when installed improperly.

Usually the only other thing that has an impact on the fuel gauge is the ground circuit to the dash display.

Good luck !

The gas gauge don't work


Hello and welcome to FixYa!
As a first course of action, please do check the fuse. If the fuse is blown, the fuel gauge won't work. If that's the case, please replace it.
If the fuse if good then the problem will be on the fuel float itself. The fuel float is located above the fuel tank. You will need to pull down the fuel tank to gain access to the fuel float. Once replaced, the fuel gauge will work normally again.
Hope this helps and thank you for using FixYa! Have a good one!

HI, MY FUEL GAUGE WORKS BUD ERRATIC, I MEAN IT DOESNT SHOW THE CORRECT AMOUNT OF GAS LEFT. WHAT COULD BE WRONG? THANKS.


In a case like this, the culpret is most likely the fuel level sending unit, which is located on the fuel pump in the fuel tank. In most vehicles, the pump and the sending unit all come in one assembly, which means in order to get a correct reading on the gauge, you'll need to replace the fuel pump. And actually, considering the fact that you have to drop the fuel tank and remove the pump anyway, it's just good measure to change them as a set.

I hope this helps! :)
