2020 Explorer ST unknown sound

[DaHuntah]

My fuel pump just makes a very low hum when it's priming. Nothing like that sound! And it doesn't do it whenever I open the door. If it's coming from under the hood it can't be the fuel pump.

It does both. Mostly when opening the door for me though.

Sounds almost like some type of actuators and not fuel pump priming.
My fuel pump doesn’t prime when just opening up a door.
You have to have the ignition on for the pump to turn on.

Well all of my vehicles do that so that’s all I know.
