When I first turn the ignition key to on position, not yet starting position, I will hear the fuel pump's motor running noise momentarily, indicating fuel pump running.
My question is that will the fuel pump be running momentarily everytime the key turn to "ON" position? if so, can the fuel pump's motor running noise be quieter due to some reasons?

yes, the car is running. I just found that after running a distance, I could hear the fuel pump motor running noise, after turn on the ignition key, and no running noise after the second turnon key, though!

Normal operation... Wait 15 - 20 seconds and turn key on, pump will run again.. OR .. Anytime engine is cranking... You're overthinking it!
thanks I guess the colder&wet weather spook me!
