With all of the advancements that have been made to cars over the years to make them fuel efficient and smooth riding, the basic systems still hold the most importance. A 2000 Buick LeSabre with a bad fuel pump can be a frustrating experience and can leave a driver stranded. The symptoms of a fuel pump going bad are sometimes ignored in the beginning as a car quirk but the signs of a fuel pump going bad should not be ignored.
Overheating Pump – When a fuel pump overheats it is actually the motor of the fuel pump that is having the issues. The fuel pump motor controls the amount of fuel that is provided to the engine. In Buick LeSabres an overheated fuel pump will present similar to one that has mechanical failure. The pump will stop functioning and the engine will stop running. However, LeSabres that are suffering from an overheated pump can usually be restarted once the motor has had a chance to cool down.
