Sounds to me like there is a bad ground to the fuel tank sending unit. This will not only keep the sending unit from showing how much fuel you have it will also keep your eletric fuel pump from working.

How do I drop gas tank on 2005 CTS Cadillac


Just go to you tube if you really want to do it yourself.Cause you will need stands and keep them level.Plus it helps to have your tank almost empty or you won't be able to do it your self.I had a 85 chevy 3/4 ton van and three of us drop it down to replace the floater and fuel pump won't never do it again.Better to take it to a garage that you trust.They have everything to it and make look easy. If you want to do it go to you tube and good luck.

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.

Recently put a full tank of gas in 199 sl2, now the low fuel light is on and the gas gauge shows empty. what to try next


Assuming nobody stole all of your gas, the fuel level sending unit is bad, the wiring to it is bad, or the instrument panel is failing.

The wiring can be accessed inside the trunk, on the left side, by pulling the carpeting up. The sending unit should read about 35 ohms when full and 235 ohms when the tank is empty. My Haynes manual says the wires are Purple, and Black-White.

If the sending unit reads correctly then the wiring to the instrument panel, or the panel itself is malfunctioning.

If it is the sending unit: the sending unit is attached to the fuel pump inside the fuel tank. You must remove the fuel tank to replace it. While you are in their you might as well put a new fuel pump in.

Gas gauge is not reading correctly. Shows a full


the problem is caused by a defective gas gauge sending unit, this part is located inside the gas tank, you must remove the gas tank to replace it.

Erratic Gas Gauge


You need to remove the tank and replace the fuel pump as the sending unit is part of the pump assembly.

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

95 sedan deville wont start and says fuel low with gas in tank


I'd start by tracing the fuel supply and return lines from the gas tank to the engine compartment. Make sure that they are free of kinks or other damage.

Next, check the fuse box and make sure there is power to the fuel pump. Trace the electrical connections leaving the fuel tank and make sure they weren't torn or otherwise damaged by the tire tread.

Hope this helps and good luck!

Fuel gauge showing empty


open circuit in the fuel level sensor. mounted in tank. as the fuel level in the tank starts to drop the arm will move past the dead spot on the sensor and the gauge will start reading again.i dont recommend diy replacement of the fuel level sender.
