What can happen to a fuel pump?
A fuel pump may not work correctly if dirt or rust particles get in the fuel line and/or if there’s a plugged fuel filter. Also, if a vehicle won’t start, and it’s not the battery, there’s a good chance that it’s the fuel pump, especially if the vehicle odometer is hovering in the 100,000 mile range. In some pumps immersion in gasoline is necessary for cooling, so keeping a gas tank on near empty too often may possibly shorten it’s life span.
