If you can some how manage to get it opened, spray some lubracant on the button inside the door. if not you'll need to replace the release cable.

2004 Kia Optima LX gas door and trunk lid will not open using buttons on drivers sdie door?

Most vehicles that have a power release, also have a manual release. Check inside the vehicle, around the location of the outside filler door. You might have a removable panel, that will reveal the fuel door release cable.

I have a kia optima 2004 that has a kill switch need to know where it is its draining my battery untill i reset it but cant find it

If you put the following into Google it shows a number of items can be reset.

"2004 kia optima reset"

One site says the Optima doesn't have a fuel pump reset, but offers this on another site

It may be under hood above brake booster, has red button to reset, the 2004 kia spectra,s are located there so i can only assume that the optima would be there to.

There is also information on resetting the computer. This will clear the engine malfunction light. There is a section in my Tips if you click on my name on resetting the vehicle ant-theft system, which is the same thing as it is controlled by the ECM.

Having said all that, drain or correctly named 'parasitic draw', is from lights being left on in the hood or trunk, or some other electrical device shorting to earth. They are difficult to find and you need a good auto-electrician.

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!

I have a 2004 kia optima with 52000 miles on it. After every fill up at the gas station no matter if I put 5 dollars or 20 to fill the tank up the car won't start unless I put my foot to the gas pedal and...

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 .

Whenever we put gas in our 2004 kia optima it does not want to start. what could be the problem?

replace you fuel system evaporative filter (charcoal canister), the gas fumes evaporated from the fuel tank are pooling in the filter causing very rich mixture and a hard start.

Fuel Filter Location

I called the dealer and the dealer said it does not have an in-line fuel filter, but there is one the fuel tank (actually, it is a fuel pump strainer part#FS233 for $10.oo).
Put the rear seats down and open the trunk for ventilation and open the gas cap for gasoline pressure release.
The fuel pump cover is right behind the rear car seats in the trunk.
Be very careful when messing with gasoline. I will be replacing the strainer this weekend, but I plan to siphon out the gasoline before I do (I just feel safer with the tank empty)

2004 optima wont stay running after fillup

semms to be like some of the vapor lines coming from thank to engine might be flooding your engine,
but also locate the fuel pressure regulator at the engine compartment and unplud the vacium hose, if you see any fuel coming out from fuel pressure regulator, or if the vacium hose smeel like fuel, then the regulator is not good.
