I have a 2004 Santa Fe with the small 6 cyl engine. Whenever I refuel (fill up the gas tank) the vehicle does not want to start. I have to give it half or more peddle of gas and hold it there to get the vehicle to start. If I take my foot off the gas at all the engine dies. This situation lasts for about 3-4 minutes. After that everything is normal. This situation only happens immediately after I fill the tank, any other time the vehicle starts up fine. Anyone have any Ideas as to what i can do to fix this problem or what may be causing it?
