Fuel Pump Connector Pinouts

My 2003 E46 330i is not starting. Fuel pump does not appear to get 12V on any of combination of the 4 connector contacts when ignition is turned on. I'd like to apply 12V to the pump itself to see if it runs but i don't know which contacts to apply the 12V to. I assume that 2 of the contacts are for fuel level sensor and the other 2 are for pwr to run the pump. I don't want to damage the fuel level sensor. Long story short, does anyone have an diagram that shows the contact layout of the fuel pump?

Thanks in advance,

R
