My daughter has an 02 Optima that had the same problem. Ran several hours of
troubleshooting including removing and checking the cannister, which was fine. I
finally found a 1-way check valve that was installed backwards (at the factory).
As soon as I disconnected the valve, the pressure instantly released. We
reversed it and the car took fuel normally. The valve has the flow arrow molded
on it. It should point toward the fill cap, not to the tank. This valve is located inside the fender by the cap.  On the Optima I removed a plastic shield in the wheel well near the filler.  The valve is a plastic in-line valve (blue and black ends) on the small vent line.
