There is no reliable way to predict how long a failing fuel pump will last once symptoms begin. Some pumps may act up occasionally and then work for a while, while others can go from minor hesitation to complete failure very quickly. Continuing to drive with a fuel pump problem can leave you stranded, and it may also put extra stress on other components as the engine runs lean or misfires. Once you notice repeated hesitation, stalling, or hard starts, it is best to have the vehicle checked soon. Once a fuel pump starts to fail, early diagnosis is key to maintaining safety and peace of mind.
