i have a 2001 Hyundia Elantra, it will not let me fill the gas tank. on 2001 Hyundai Elantra

when i try to put gas in the tank it clicks nozzle off time after time, like the tank is full. I can not get more than 5 gallons in after several minutes trying. What is wrong ? I looked at the hoses, seem to be no kinks or twists. What is th ccv that you refer to in other post? where is it located?
