I have heard the fuel pump run from the time I turn the switch on, until the light goes off. Have heard since it was new.
Could that be what you hear?

What you are hearing is the fuel pump pressuring up and stops as the light goes out. The light is the ECM booting up and checking the system. Does it every time you turn on the key.
