A healthy in‑tank fuel pump usually makes a soft whirring sound that you might barely hear for a second or two when you turn the key on before the engine starts. A failing fuel pump can become noticeably louder, making a high‑pitched whine, buzz, or humming from the area of the fuel tank. If that noise changes suddenly, gets much louder, or is accompanied by performance problems like engine hesitation or stalling, it may be a sign that the fuel pump is failing.
