have the same problem, check engine light came on with code P0441-evaporative emission control system, incorrect purge flow. My mechanic is going to to a pressure test on the fuel system, but thinks it will be the fuel pump that needs to be replaced!
First of all, get a new mechanic. Next, find one that will check for vacuum leaks in the fuel trim. Today’s fuel tanks are vented back into the engine. A "Carbon Canister" is supposed to absorb the vapors and then feed them into the engine in a controlled manner. If your canister is saturated or the purge valve stuck open, the fumes can "flood" the engine while refueling. To narrow your problem down, try holding the throttle wide open when you start after refueling to clear the vapor quickly. If you needed a new fuel pump, you'd always have difficulty starting your car, if at all...not just after refueling.
great answer! I was going to call the Tappert brothers but your answer was spot-on understandable and very much appreciated! Thank you. it worked!!
