I have a 2007 Hyundai Santa fe every time after I
put gas I have trouble starting my car I have to
pump the gas and turn the key when it starts i have
to keep pushing on the gas for a few min before I
could put it in drive and my car stays on but I only
have to do this when putting gas after that my car
turns on and off just fine
It may be flooded after fueling up , you're not pumping the gas but when you depress the pedal to the floor and hold it you may be canceling the fuel so that a flooded engine will start .
I have a 2006 Hyundai Santa Fe and had the same issue; car wanted to stall out and not start only after pumping gas. I replaced the purge valve and had no more problems.
