Most likely your fuel pump is dead, but on your first post you said that you already changed the fuel pump. Did you buy a new fuel pump or a use fuel pump? You have current to the pump but the pump is not coming on you have a dead fuel pump. Hopefully you didn't buy a Wing Wang fuel pump from eBay or Amazon. People should stop buying cheap crap off of eBay and Amazon. If you can't afford to buy decent parts you can't afford to be driving a BMW.
