I pull the most rearward relay and the pump stops running, but there is still a high pitched noise. I plug it back in and it runs again.
That is the fuel pump relay. Swap it out with the one next to it and drive it. The rearmost relay should be red. If not, buy one. It has extra goodies inside to protect your elec system.

Also, high pitched noise coming from where?

EDIT: Oh Cripes. I need to look at dates.
