2004 Hyundai Sonata Q&A
2004 Hyundai Sonata Question: Hard start after filling tank with gas.
After I fill my tank with gas. Try to start my car, all it does is turnover and turnover (like it is flooded) and will not fire. I then hold the gas pedal to the floor (did not pump the pedal) and proceed to start car. It does start right away, I hold my foot on the gas pedal and hold it there on a higer idle for about a minute. Then I can drive away. This is the 5th fill (5 weeks) since it started to do this. - dandrews
How often do you drive the vehicle, stop it, then restart it withing 5 minutes? Basically recreating the same condition, but without filling the fuel tank? Do you always fill the tank? And to you "top it off"? - Bret Bodas
change your purge valve - Visitor

check engine light on. negative purge flow indicated. hard to start after fill-up. Do I need evap purge valve? Where is it on engine? Help please.
this happens every fill up, it also has a surge or it feels like a momentary power loss when idlig or accelerating. just had timing belt replaced & tune up. these didn't help any. also cleaned out ...
