What does it mean when your fuel pump is whining?
If the fuel pump is blocked by engine gunk, dirt, impurities in the gasoline or anything else, it will respond with a whine or some other very noticeable noise. Debris in the fuel tank can be sucked into the pump most easily when the tank is low. This debris gets caught in the pump and reduces the pressure.
What kind of noise does a pump make?
Cavitation noise typically sounds like a high-pitched crackling and transitions to an intense rattling sound when the effect intensifies (i.e. lower NPSH). Cavitation noise contributes to the overall noise emitted by pumps and systems and necessitates further outlay for any noise control measures that are required.
Why does my fuel pump make a loud whine?
Most fuel pumps will produce a quiet hum during their normal operation, however, an excessively loud whine coming from the fuel tank is usually a sign of a problem. There may not be enough fuel, a damaged pump, or contaminated fuel inside the system.

What causes a fuel pump to whine when you start the car?
A low fuel level can cause the engine to work much harder to build the necessary pressure to pump the fuel. To analyze the problem, start the car when the fuel is low (below one-fourth tank) and listen for the sound. If the whine is audible, fill the tank immediately. When you start the vehicle again, the whine should be reduced or absent.
