A friend of mine has a 97 GT and posed a question for me to answer. He sais that when he turns the key on, a light comes on the dash that looks like a gas can with an X over it. It last for about 30 sex to 1 minute. He says it has gas in the tank.

Does anyone know what this light is and why it comes on?
