Are you certain it is the secondary air pump or is it the engine cooling fan? The engine cooling fan will come on and off as you drive.

Yep! Very good quote. I make a test today and the one I hear IS the engine cooling fan so definitely my secondary air pump is not starting at any time. First thing I would like to know now is if I have a failed pump. Any easy way to test it?
