Your Electric Fuel pump which is located in your fuel tank could be on it's last legs, try changing the fuel filter if you haven't done so yet and see if that helps.

You may have a bad fuel pump check valve that is letting the gas return into the tank. To check, connect a fuel pressure tester to the test port on the fuel rail. Check the pressure with the engine running, and turn off the engine and check to see if the system is holding fuel pressure.

I have a 2000 3.8 impala that wont take gas and the gas gauge stays full.


Wont take gas and the gas gauge stays full? This question really doesn't make sense. But if you cant put anymore gas in the car and the gauge says full then you have a full tank of gas. If the gauge always says full even when the gas tank is not full then the sender unit is failing or the gauge itself.

Every time i am putting gas in my car it would shut off or kick back gas. I have tried different pumps even try puttin gth egas in slow or not putting the nozzle in all the way and nothing helps


Sounds like you have something stuck in your gas tank maybe someone put something in your gas tank perhaps you might consider a good flash light and a pen open the cap insert the pen hold tight and put flash light in filler neck flap hole to see what kind of obstacle you have stuck in your filler nozzle neck if your unable to see anything you might consider taking the car to certified technician for service to you clogged gas filler neck.

Where is the fuel filter on a 2000 hyndai elantra


If it's anything like the 2000 Hyundai Accent (which it probably is) it is mounted on top of the gas tank. First make sure you have a tank that is less than half full (8lbs per gallon), then jack up the car and place jackstands in a secure place. Then place a jack and 2x4 under the tank. Remove the 2 straps and slowly lower the fuel tank, it's most likely on the passenger side on top of the tank.

I have a hyundai elantra 2000 have a code po442 and gasing up it act like it full so what the problem also it has over 120,000 miles on it


Hello! The 2000 Hyundia line has a common fault in the design of their evaporator system; The handling of fuel fumes. If, at any time, you may have overfilled the gas tank, gas will saturate the charcoal canister. This causes small pieces of charcoal to circulate within the evaporation control system, clogging it up, not allowing the gas tank to be filled. Does your Elantra have trouble accelerating, run rough, or stall? Probably so. Take the car to someone you trust and have them flush the evaporator system with the canister removed. You will more than likely need a new canister.

Unable to put gas into the tank. Pump keeps shutting off like the tank is full, it's not.


There is a filter on the tank vent that is plugged. It is not letting the air escape from the tank during fillup causing positive pressure which will will shut off the gas pump. I don't know where it is on your model but some are under the back behind the fuel tank. It is usually a 6" square plastic box with a hose on it and louvers on the sides.

Can't fill the tank


There is a breather tube fitted to the tank which allows air to escape when you fill it with fuel.

That is either blocked or compressed.

When you take the filler cap off is there a gust of air in or out of the tank

Gas tank


hi first of all i will address yours first as yours doesn,t have a engine check light on the return pipe on the petrol tank is blocked not allowing the tank to breath as your filling [causes are non return valve stuck closed trapped pipe or the pipes collasping . as for the guy with the engine light on you may well have the same problem but i would get the engine lights code checked as it could well be a problem with your emmissions venting your tanks fumes out yates210456
