Fuel pump priming when doors open?

[LSX Z28]

My 2020 2500HD gas sounds like the fuel pump or something similar starts up when I open a door. Is that normal? I only notice it when it has been parked in the garage for a while and I go out after it has been sitting for a while. It also did it the other day when I shut the hood after it had been left open for a few hours.

Yes, if the truck has sat for a decent amount of time, the pump will prime back up at first unlock. Only after it's been sitting still for a while. Merry Christmas, as well!

Thanks! I assumed that it was normal, but figured I would ask. Merry Christmas to you as well!

My 19 Tahoe does the same thing. Normal

Does anyone hear static at idle with radio off and air off? Sounds like noise coming from the speaker or behind instrument cluster. Even changes/increases with engine rpm until it stops when rpm is up around 2k. Sounds like speaker static up on the dash. Can hear it at stop light or in driveway.

Cool, samthing with my 2020.
