Fuel gage sending unit is probably the culprit. It will only get worse. It is a part of the fuel module in the tank. Parts are from 275 at AutoZone to much higher at napa and the dreaded dealer. takes about 2-3 hours total to change.

My fuel needle showe quarter and my ibiza 2006 shut off need more 5 liters


Fuel gauges are never precision instruments, but you can fix this to show at least empty when it's empty.
If you can't access the top of the fuel tank you need to drain and then remove the fuel tank and take out the fuel sender unit. Otherwise just remove the sender unit from the tank.
Hold the wire with the float on it firmly and bend the wire to raise the float slightly.
Replace the float and check the fuel gauge reading. Repeat the procedure until the gauge gives an acceptable reading.
That should stop you from running out of go juice before the gauge hits zero, but you might not have a completely full reading when you fill up. Live with it..

Today while I was driving, The instrument where it telles you how many miles left till empty read 27mi. all of a sudden it started counting down rapidly, within seconds it had went from 27 mi to 4mi left...


Sounds like float in fuel tank is sticking. Usually caused by using cheap gas. Fill it up and add a bottle of STP gas treatment. It might take more then one tankful w/STP to clean it completely. TIP: don't rely on the computer generated "mileage left" especially when that low on fuel, that is only an estimate. And also don't let it get that low on a regular basis because it will damage your fuel pump, fuel is used to cool electric pump in fuel tank and running it that low will shorten the life of your fuel pump.

I have a 2004 pontiac montana. for about two years the fuel guage would fold over and read 125 degrees when the tank is full. it woulld stay there until tank was empty and the needle would drop to empty,...


It could be a bad fuel gauge in the dash unit, but....
Usually it's "The bad".
The fuel level sending wipe arm and windings on the fuel sender wear and send erratic readings.The only cure is a replacement fuel gauge sender.
The check engine light should not be related to the erratic fuel readings.
"The good".
If you have over 200,000kms or 120,000 miles on your van you need a new fuel pump anyway,so have a complete assembly put in which will have a new fuel sender on it.

Speedometer or fuel gage?

If speedometer which is bouncing around, it is likely a bad ground near where the speed sensor wire harness (which connects the speed sensor to the rest of the "network") exits the transmission housing. It's at the very back of the transmission (you have a 4T60E trans) to the left of where the right side half-shaft leaves the trans housing. Just look for damaged wires. If none, replace the speed sensor for $50-60.

If it is the fuel gage, the sensor is probably not "zeroed"--it's reading wrong, too high, and if it were to start at true "empty", it would read right. Thus, the gage is always reading a little high (maybe a 1/8-1/10th of a tank too high?). This isn't a problem until to stop, start, or turn quickly and cause the fule to slosh around in the tank and starve the in-tank pickup which sends fuel to the engine.

If it is the fuel gage, you should simply put as much fuel in as you can and see if the needle goes far above "F". If it does, note how far it went and then practice filling the tank when the needle is that same distance above "E".

Hope this helps.
