Car stalls when fueling!!

Help!
I have a 2000 V6 Sonata> When refueling, the car will begin to run rough and shortly thereafter
shut down. After fueling, the car is very difficult to start. It will take several turns of the ignition
before a clean start. Once the car starts, there is no problem starting, until the car sits about 20 to 30 mintues.

Thanks in Advance

You do realize you're supposed to SHUT THE CAR OFF when fueling, right? Not only is fueling a running vehicle a fire hazard and thus illegal in many locations, but the fuel system is a closed system and needs the gas cap to be properly seated in order to run properly.

On my sons 2005 Sonata if the gas cap is not tight, the Check Engine light will come on.....I'm pretty sure it reads the tank presure or something along those lines..... In this state, car needs to be off when fueling or major fines........ Even if the cap is not tight, he says the light will come on.... Tighten cap and turn off and see what that does...........Swampy

Hi,
New to the forum, and saw your problem. THere is a TSB on this, can't remember TSB #.
Changed the valve noted in the TSB, and never had the problem again. Took 15 minutes....Almost a year now.
Have 2000 Sonata 2.4L 4cyl.

Stalls while fueling????????? Sounds like it stalls because you ran out of gas. May even be a sign that you have some serious problems with your ride. Try turning off the ignition and fueling up. Then close the cap and start it up. You may have gotten some bad watered down gasoline too. Man, stop going to that gas station.

You may want to check the purge solenoid valve to see if it is stuck open. If it sticks open , when you fill up it pushes all the fuel vapors from the fuel tank to the engine and will flood the engine with too much fuel vapors. You could also pinch off the hose to see if it cures the hard start.

or maybe just dont put fuel in the car when its running
