I was in an accident about a year ago only cosmetic damage or so i thought. After about 6 monthes the car started having trouble filling up at the gas pump especially in cold weather. You would set the pump to fill the car and after a few gallons or so it would read it was full. Then for the next 8 -10 gallons or so you would have to pump the rest yourself, but the pump would read full every half gallon so, it would go half gallon then CLICK it would read it was full then half gallon CLICK, Half Gallon CLICK it gets really annoying but now it doesn't do it as much now that it is the summer i dont know why any ideas on how to fix it or what could be the problem??????????????
