Buzzing sound ?

Went into my garage this am and heard a buzzing sound. It was coming from my new 21he. The sound was coming from the rear underside. I started the lc and turned off and buzz went away. Could this have been the fuel pump?

Just part of an emission system self check when the truck is off. Common and ok.

How long does it run for? Will it start on its own or starts after you turn ignition off? Thanks for the info...

It runs about four to eight hours after power off. This Toyota system uses the same evap tech across almost their entire lineup
