can you describe the sound? is it ticking or knocking?

Sounds more like an electronic motor, I am thinking it may be the fuel pump or maybe the electric lift gate some how priming itself

fuel pump I would think... should prime itself as soon as you turn the key to the on position before you actually start the engine...
