QuestionQUESTION: My 1999 deville's gas gauge seems wrong. When the gas tank is empty, it keeps moving between 15gal and full. When the gas tank is full, it shows full. I found some answers through the Internet, but most of all are not helpful. Could you please help me?
ANSWER: There is a float mechanism that measures the amount of gas in the tank by sending back different voltages to the gas gage on your dash and there is a fault with the meter in the fuel tank. You need to replace it.
