Buzzing from the rear-end

[Marty94]

Hello guys,

I have no ideas left with this problem, every time I switch the ignition to (On) my car start buzzing from the rear end, for about 10 seconds, the it does the same for about 5 seconds when it starts.

After that every time I touch the gas pedal in neutral or in gear the buzzing starts till I let go of the gas pedal.

I have no ideas left, if someone could let me know what this buzzing is. Sounds like it's coming from the diferencial or hicas system. The sound started out of nowhere.

PS. I'll leave a video with the sound.

Thanks in advance.

It is a gtst without active diff, right? I'm 99% sure the noise is a pump dying, almost certainly the fuel pump

You guys were completely right, I took out the fuel pump fuse out and the noise when away when switching the ignition to (On).

I thought it wasn't the fuel pump because it sounded like it was coming from the bottom, not the boot. 

 

Appreciate the help, I'll start looking for a good fuel pump.
