Erratic Fuel Gauge Operation on Chevrolet Corvette

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

Fuel Gauge shuts down after fill up. Check gauge light comes on as well. At about 3/4 of a tank, the gauge come back on and goes off again at around half a tank. At fill ups, the gauge never fills past 7/8s of a tank. I have heard every fix under the sun on here, which is the right one? Sending unit? Which side" Re program? Replace the entire fuel system at the cost of thousands? Because a gauge doesn't work? Why? Techron?, used a ton of that!
fuel gauge quit working when it reached 1/2 empty (from full tank). car continued to function as normal. currently at dealer for fuel level sensor replacement. this is a time consuming process as the fuel tank AND transmission have to be pulled. car is at dealership going on day 4.... some 2014 corvettes had a "fuel fill siphon pipe" failure (as this car did at 5,500 miles), and the above-mentioned failure may be related.
I have had the same problem....check engine light....fuel gage stopped working at about 3/4 tank, now it is not working at all....I have not fixed it because I keep hearing it will happen again, is there nothing out there to fix the problem for good.
Some time it work some time it not
Fuel gauge was working fine when I purchased the car a couple of months ago, filled it up a week ago, showed less than 1/2 a tank on the gauge, the dealer acknowledged a problem with the sensor.- They need the car one week for the fix - They need to remove the transmission and the tanks to get at the sensors/pumps. Hopefully, the new parts hold up longer than the originals. Needless to say, extremely apprehensive about the upcoming surgery!
Same as reports that I am reading. Mine started at around 32K miles an then quite until 60k miles... Same symtoms as all error messages than returns to normal...But lately it is occurring more frequently...have reported to Chevrolet Technical an opened a case #..Seems this is common with C5,C6 & C7 models.. I do not understand why Chevrolet does not do something about these faulty sensors other than trying to make you pay 2500 to 4500 for repair of THEIR choice of a faulty product..
Engine would die while driving, sometimes it didnt start, all lights work when trying to start it , you can hear the starter trying to turn the engine but nothing, battery is new so I assume its ok,,then just ran fine till this happen again,, cheked the fuel pressure and nothing! There was no gas getting to engine, so by then I knew my problem was a fuel related problem,, my dad gave some hits to the tank and then pushed the car up and down from the trunk while I was starting the car, then boom! It started again,, we knew by then there was a problem with the fuel pump , so we now have to replace it,,
fuel gauge goes back and forth between full and empty a few times for the first 8 to 12 miles after a fill up.just happened on a 2000 mile trip. not fixed yet. just got back.
Same issue with the fuel gage.
has not been fixed. I am told the whole fuel tank has to be removed to repair the sensor problem. That's $1300 apparently. BTW I am in Canada and don't have a ZIP. My postal is L7P 0B5
when I fill up lately and start driving I get a service fuel system, check engine and low fuel with fuel gauge showing empty. after a while the fuel gauge will start reading normal sometimes only half a tank or full, and check engine light stays on
Not fixed. A reset of CEL would allow fuel gauge to read 1/2 full when completely full. When fuel dropped below 1/2 tank the gauge would then show correct fuel level. Apparently it was reading the drives side fuel tank only. Passenger side sending unit is what usually fails. Had to perform the CEL reset frequently.
Right fuel pump, left sensor and cross over pipe replacement. $1826.00 plus tax.
Low fuel reading after filling tank, i was told sensor has carbon build up and must b replaced
fuel gauge showing miles remaining is off while car is moving and the sometimes shows the correct remaining miles Need recall wire fixed.
The gas gauge in my 2010 Corvette simply stopped working. First the dealership reset the gauge and about a week or so later the gauge stopped working again. Then the dealership replaced the sending unit within the pontoon tank. Within about a month the gauge again stopped working again. This time the dealership consulted with engineers in Bowling Green and it was recommended that the entire fuel system be removed and replaced. Both pontoon gas tanks and their sensor assemblies were removed and replaced. The problem has not occurred again but I have had several other continuing electrical problems with the vehicle including the rear trunk button needing replacement, the vehicle not recognizing either key fob and now the warning light for my air bags intermittently (about 90% of the time) lighting on my dashboard.
The sending unit doesn't have to be replaced, they just need a bottle of Techtron and it fixes the issue.
Gas sensor failed
My fuel sensor either went out or is doing what it did before. I had a diagnostics test run and Sensor B has the problem. It reads "Service Fuel System" on the dash and shows empty on the fuel gauge. This actually happened miles back. Not sure how many, but probably when I had it in the 35,000 miles range (but can't remember). I drove a few weeks on it, and then it started working again.
