GPR Buzzin?

I have been trying to do a buzz test for my injectors. Problem is I cant hear my injectors buzz over the sound of the glow plug relay. Is this meant to buzz? How loud should the injectors buzz?

What I do is turn the key on and wait for the vac pump and glow plugs to go off, then run the buzz test. To do the cct right after, you will need to recycle the keys to reactivate the gps

I've never heard of a glow plug relay buzzing, but if you think that is it just unhook one of the little wires and see if it goes away.

I had the hood up and turn on they key and heard a buzzing. I think I heard a faint buzzing that stopped but i dont hear the back and forth individual buzz that everyone talks about. Then I keep hearing the buzzing. I assumed GPR and put my finger one of the big wire going to it and you could feel it vibrating.. I wouldn't call it a loud buzz
