i think my fuel pump relay is bad but i dunno which is what, ive researched and has no luck, some help with be awesome,

i crank the car has i have my hang on the top of the pump bracket, as the car cranks the pump pulsates power on and off quickly, and now the pump start up for a second then stops, i ran direct power to the pump and it was work fine but the battery wwas pretty much dead by then so the car wouldnt start

That could be a bad fuel pump relay, bad engine timing sensor, bad engine harness, or a bad DME. Understand that the DME controls the fuel pump relay and only engages it when it sees timing data from a rotating engine.

Start by replacing the relay and timing sensor(s) with new BMW parts.
