What size engine do you have?

This sounds like it could be a couple different things. It seems to be something related to fuel pressure. Just turn on your ignition to the run position, do not start, and see if you can hear a whine. This would be your fuel pump coming on. It should only be audible for a couple seconds before it shuts off. This is where I would start first.
