2004 BMW 325 - Battery or fuel pump?

My 2004 bmw 325i has been basically sitting 9 months, It starts every time. It has been driven short distances. The battery went dead so I charged it and tested it was good. Put back in car and now the car will not turn over. The mechanic thinks its fuel pump?? Help.

Fuel pump does not affect the engine turning over. A failed fuel pump will prevent it from starting though.
