I know on my '01 it's bad fuel level sensor, I would venture a guess that it would be the same for your 2000. But then again I'm not 100% sure....

Brooks, there has been some issue with the sensors but I would suggest you try a bottle of Chevron's Techron at the rate of 1 oz per gallon of gas. Do this for at least one tank and maybe two. It contains an agent that will help clean the sensor and could correct your problem. Be sure to get the pure Techron and not the Pro Gaurd with Techron. It is expesive but may solve you problem. If not, it will still offer many benefits in cleaning your injectors, valves and comb chamber.
