Problem Description and Possible Solution

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.

Gauge reads full, then drops to empty, then back to full every 4 or 5 minutes when traveling. Doesn't matter whether there are 3 gallons of gas or a recently filled tank. Haven't found a solution yet.
Gas gauge has read full every since I bought the truck. It doesn't move at all. Would love to get it fixed. . I honestly don't know very much about mechanic work. I am open to all thoughts and suggestions!
Gas tank is full, but gauge needle drops to empty
gas gauge reads full all the time... just like my s10 pickup... hmmm
fuel gauge reads full one minute then empty the next. don't know how much fuel is in the tank
Upon start-up fuel gauge goes to full then to correct level, then back to full, then bounce back and forth between proper reading and full. Then would read higher than normal unless made a somewhat sharp turn or over rough terrain then would make its way to proper level. Each day worse and worse.
Having fuel problems every time I turn off key fuel goes down and not giving me right fuel reading wasting fuel than expected
Level always reads high
Fuel gauge hasn't worked for years. I just keep track of my mileage.
The problem was somewhat fixed by replacement of the fuel injection system.
The gauge still isn't totally accurate. Also the low fuel lite comes on when parked in a downhill position.
No reading fuel when is full
Won't let me put more than 5 gallons of gas in without it spitting gas back out, gas gauge shows 1/4 tank, acts as if it is full
erratic fuel meter
fuel gauge stays at full
This has been an issue for years, but only in Oregon, with DEQ making me fix it do I have to address it. Dealer wants almost $500 to fix it (including labor). Looking for a mechanic to do it for less. What a rip.
Never fixed, sold s10
I will go to full then drop to empty
Fuel gage stays at full position at all times
My fuel gage reads 1/4 tank. I take off driving & come to a stop & the car shuts off. I go to start it and it hesitates before starting, go to make a r turn & it shuts off again. I will replace the fuel module as suggested & hope this fixes my problem.
needle on dash with full tank reads less then half.
At first, gauge would only go to almost half tank and fall below empty. Now it doesn't do anything. Where do we look first for the problem?
