Question about 2002 Kia Optima

Open Question

I can't put gas in my '02 Kia optima. How can I fix this?

No matter how slowly I pump the gas, the pump switches off as if the tank is full. I've had my valves cleaned out, and it works for one fill-up then back to the same problems.

Two things come to mind. You broke the pressure seal to the fuel system when you took off the gas cap. The fresh gas rushing in disturbs any dirt or debris on the bottom of the tank.
Next time you use the car when you arrive at our destination, simulate what you do when you fuel up. This will mimic everythig except the new fuel rushing in. If it is still hard to start you know it's something to do with the evaporative fuel system. If not, you need the fuel tank inspected .

SOURCE: we have a kia sportage that wont take gas when

have someone check the vent valve and hose, a common problem is spiders go inside the vent hose and make a web nest, this blocks the system. so when filling the tank the air in the tank cant be release and so pump shut off and fuel sparys out, take a look , bet youll find a spiders nest.

SOURCE: Cannot fill gas tank on 2002 Kia sedona. Even when

I have a Kia Sedona 2005 and I can't fill it up with gas without the pump kicking off and I have tried several gas stations. Sometimes I can get a few gallons in with no problem but then it kicks off again and I have to spend twenty minutes dripping fuel into it until I loose patience. Help me!

How do you restart a 2010 Kia Optima after it runs out of gas?


Hey. Put gas in and turn ignition on run and off 5 times slowly( don't start up the car) every time you turn ignition on you will hear pump priming for few sec at the time. After that you should be able to restart your car.

How can I fix the gas intake sensor in a 2003 kia optima?


Do not put the pump nozzle all the way into the filler neck. This should work because you are letting the gas replace the air in tank.Pressure in the tank will shut down flow into tank.

2005 Kia Optima w/ Trouble code PO441; stalls after filling up with gas - how do I fix it?


Here's a link for p0441 (not po441) http://www.obd-codes.com/p0441
P0441 Evaporative Emission Control System Incorrect Purge Flow.
Since it happens when it fills up, you'd have to look at what happens with a almost full tank (you stop about a gallon before full), vs a full (gasp pump stopped when full) tanks. Something might be happening when gas gets to far up the filling tube. Maybe there is a vent line with a valve that's getting gas in there causing the fault. I'm not a kia expert, but If stopping the gas pump yourself fixes the problem, then stop "topping off"

I have a 2003 kia optima, When trying to pump gas, the gas pump shuts offl but i am sure its not.


My daughter has an 02 Optima would not take fuel unless it was down to 1/4 tank due to back pressure (similar to being full). Ran several hours of troubleshooting including removing and checking the cannister, which was fine. I finally found a 1-way check valve that was installed backwards (at the factory). As soon as I disconnected the valve, the pressure instantly released. We reversed it and the car took fuel normally. The valve has the flow arrow molded on it. It should point toward the fill cap, not to the tank. The valve is located behind a panel in the wheel well, near the filler. Small plastic with a blue and black end (at least on my model). Hope this works!

Can't put gas in my 2002 Kia optium.


gradually put the nozzle in while pumping till you find the sweet spot where it stops backing up.There may also be air in there, so put nozzle part way in to allow air to escape first.

Gas clicks like full when its not full


It sounds like your tank vent is pluged. If you look under the vehicle near your filler spout, you should see the filler spout hose leading to the tank and a smaller hose next to it. The smaller hose is the one that I am concerned with. See if it has some how collapsed with age. In a few rare cases I have seen the vent hose made inside of the filler hose ( ford ranger I belive) and you won't see that one. What happens is when you put the fuel in, the air must come out, so it burps for a better way of putting it and it forces fuel out with it. Putting the filler hose in farther and tighter won't help, but you could try to slow the rate down so as to give the air more time to escape.

2006 Kia Optima/release button for fuel tank does not work


you may want to check all the fuses first.

then see if you can remove the switch and test it . if you dont know how to do this please take it to someone who can test this for you.
on an 06 kia with a problem like that i would just have the dealer fix it really quick for you.
the problem is the fuses or the switch for sure.

2004 kia optima


My 2004 Optima did nt have filter exactly. There is only a filter bag type device on the inlet to the fuel pump. The fuel pump is located in the gas tank and is accessed by rolling back the carpet in the trunk... I have 165K on mine and never changed this filter. No parts listed at NAPA or other store for filter. Just put some injector cleaner into the gas tank every mont and should be fine
