fuel pump relay buzzing

I have the same problem with my 92 Supra Turbo.

Has anyone figured it out yet?

So far, I know the circuit containing the Fuel Pump Relay also contains the Circuit Opening Relay ( located on the passenger side kick panel ), and EFI Main Relay. One of the VSV below the intake may be related too.

3 things click simultaneously once, when I connect the battery then the Fuel Pump Relay buzzes.
