Why does my radio make a constant speed noise?

Curing Radio Noise. Likely culprits include the ignition, the alternator or even a fuel injector. Constant-speed noises are usually caused by an electric motor–most likely the electric fuel pump found in the tank of most modern vehicles which runs at a constant speed anytime the engine is running.
