SOURCE: fuel gauge not working all the time.

This is a normal concern.
The instrument cluster uses 4 different operating modes to calculate the fuel level:
Anti-slosh (default mode)
Key OFF fueling
Key ON fueling
Recovery
After a fuel fill up, the time for the fuel gauge to move from empty (E) to full (F) ranges from 2 seconds to 55 minutes depending on which operating mode the fuel gauge is in.
The default fuel gauge mode is called the anti-slosh mode. To prevent fuel gauge changes from fuel slosh (gauge instability due to changes in fuel sender readings caused by fuel moving around in the tank), the fuel gauge takes approximately 55 minutes to go from empty (E) to full (F).
The key OFF fueling mode (2 seconds to read empty [E] to full [F]) requires 3 conditions be met:
The key must be in the OFF position throughout the entire refueling of the vehicle.
At least 15% of the vehicle's fuel capacity must be added to the fuel tank.
The instrument cluster must receive a valid key ON fuel sender reading within 1 second of the key being put into the RUN position. The key ON sample readings are considered valid if the fuel sender reading is between 15 ohms ± 2 ohms and 160 ohms ± 4 ohms.
If these conditions are not met, the fuel gauge stays in the anti-slosh mode, which results in a slow to read full (F) event.
The key ON fueling mode (approximately 90 seconds to read empty [E] to full [F]) requires 3 conditions be met:
The transmission is in PARK (P).
The key is in the RUN position.
At least 15% of the vehicle's fuel capacity must be added to the fuel tank.
In key ON fueling mode, a 30-second timer activates after the transmission is put into the PARK (P) position (automatic transmissions). When the 30-second time has elapsed and at least 15% of the vehicle's fuel capacity has been added, the fuel gauge response time is 90 seconds to read from empty (E) to full (F). When the transmission is shifted out of PARK (P), the fuel gauge strategy reverts to the anti-slosh mode. The key on refueling mode prevents slow to read full events from happening if the customer refuels the vehicle with the key in the RUN position.
Recovery mode is incorporated into the instrument cluster strategy to recover from a missing fuel level input during a refueling event. Missing fuel level inputs result from intermittent opens in the fuel sender or its circuits. Recovery mode (empty [E] to full [F] approximately 20 minutes) is initiated when the following 2 conditions are met:
The instrument cluster is in the anti-slosh (default) mode.
The actual fuel level in the tank is greater than what is being displayed by the fuel gauge

I had the same problem. My battery was going bad. When I replaced it with a new one, the fuel gauge worked fine.

Definitely the gauge can be changed, provided the float in the fuel tank is OK, i.e. no leaks. This float connects to a potentiometer which records the current flowing thru it and displays it in the gauge. So before replacing the gauge measure the current and match that against the quantity of fuel in the tank...............sodeep

SOURCE: fuel gauge problems

Remove the sender wire from the fuel tank and short it to ground (metal part of tank).

If the fuel gauge goes to full then your sender unit is faulty and replace it.If not ,please come back to me .

Please leave positive feedback if you feel I have helped you.

Thank you

What causes the fuel gauge to read only half tank


My friend on your attempt to renew the fuel pump which actually is connected with the fuel gauge you either damage the leveling gauge either by bending it or scratched it to a place where the gauge shows half tank. It is better to remove again and very slowly and carefully check for any slight faults.
Good Luck.

Town and Country Van running out of gas and guage says half a tank what could be the problem?


If your fuel gauge is showing you in accurate readings this is normal to all vehicles that are not used to fill-up gas full regularly but sometimes the cause of the inacuracy is due to faulty float valve in the gas tank you need to replace it

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.

hi it can really only be two things, first is the fuel sender on the pump inside the tank it could be stuffed or sticking causing a false reading, second it can also be a faulty fuel gauge on the dash.

Fuel gauge dropping to e saying low fuel when tank is half full


you may need a new fuel level sensor. sometimes the sensor gets a coating on it from the fuel and you can put in Chevron Techron, fuel system cleaner, to clean it, sometimes that will get it working again. If not, then it will need replacement.
