The first time after I refuel, my car has trouble starting. After about 10-15 seconds, it will finally start with some help from the gas pedal. I dont have any trouble starting the car afterwards, only when I refuel. I tried refilling my gas tank half way instead of fully to see if it would continue and it still has the same problem. I also notice that when I pull the fuel pump, the hose leaks gas all over my rear quarter panel for a second as if the hose never got closed off. No CEL lights are on either but I have yet to scan it.

Fuel cap? Fuel filter? Purge valve? N80?
