If fuel injected, the pump is usually a constant whine. If an on-demand
pump, you might hear and puttering arcing sound every few seconds at idle,
more often when driving. If a mechanical pump, no noise.
Computers make a LOT of noise as well as up to dozens of other modules in
your vehicle. My particular vehicle, which I have yet to install my radio
equipment in is PWM, Pulse Width Modulation, controlled. I can hear
drifting buzzing sounds quite well up to 500 MHz.
