A couple months back I had a front-end collision with my Lancer and ever since then I have been experiencing a loud hum on startup that seems to be coming from the back of the engine bay on the driver's side. I have a hole inside my intake manifold which seems to be the fuel pump attachment and I'm thinking it could be coming from that because it gets louder on cold startups. I included a video with the sound and if anybody can help identifying this issue it would be greatly appreciated, thanks.
