    I have a 02 Hyundai Accent that has the same problem. Sometimes it will warn you it is backing up and getting ready to run all over place other times it just does it. You can only put about .98 at a time in it which makes for a difficult morning if you running late or if its freezing outside at anytime it's difficult.



    The gas mileage has become awful also, along with the engine light staying on now. Which it's throwing an o2 sensor problem, there is more than one of those on the car it's by process of elimination.



    We have did some research on this and believe it to be a problem with the car being overfilled with gas at one time or another. It seems if overfilled it runs back into charcoal canister which stops up the lines and then the problem begins.



    I have talked to Hyundai and the parts alone for this is $280.00 plus labor. I am just dealing with the issue at this time because I have other pressing matters, but man is this annoying!

    same issue, cant put in gas for more than like 10 seconds, i have to put it in VERY slow. Also i can hear a hiss sound while driving every 45 seconds, could this be from the pressure?

Many cars and trucks do that. You just have put the gas in slower.

1987 Honda prelude gas guage reading half full tank is empty why?


there is a fuel float in the tank just like in the back of a toilet. you have to pull up back seat cushions to get to it i believe. it will be a round plate type with a couple wires coming out. undo it and pull up the float and probably pump too, i dont know if the pump is in tank or out on that car. its easy enough you dont have to pay someone to do it. good luck

The gas gauge for the front tank on my 1992 F150 is stuck past full


You probably have a ground wire not making contact to ground on the front tank sending unit. OR the sending unit itself inside the tank is faulty. Either way, when a gas guage goes to full all the time (empty or full), this indicates that NO ground is available for the sending unit.

Gas tank


each tank must have its own fuel pump so theres no feed to aux tank so one of the empty fuse holders must be for the tank

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.

The problem is that there are updates for the computer in your vehicle.The dealership can do what they call a flash and install those updates.The bad part in my opinion is that they dont inform the public of this and they will try to sell you a new computer when you dont need it.

Gas gage constantly says full when it's not!


Unfortunately this is most likely the fuel pump module, which includes the fuel level sensor also. This should be diagnosed more thoroughly with a scanner, a good scanner will be able to check instrument cluster separately to confirm the gage is working right,and check for trouble codes that may not light any warning lamps. Hope this helps. Rate me please.P.S. Dont use that fuel station any more.
