Driving with a bad or weakening fuel pump is not recommended because it can fail completely without warning. A failing pump can cause your engine to stumble, lose power, or stall in traffic or on the highway, which creates a dangerous situation. You might also find that the car will not restart once the fuel pump finally quits. If you suspect fuel pump trouble, it is safer to have the vehicle inspected before continuing to drive long distances.
