If you start refueling again, can you eventually fill the tank?
The tank vents to a canister, the canister then vents through a vent solenoid. The vent solenoid may be stuck closed, this is the most common cause. The vent solenoid is located over the right side muffler. Try disconnecting the vent hose from the solenoid to see if this eliminates the problem. If it does, replace the solenoid.
