BMW 335 I 2008 Manual

Hello everyone, I ask all the friends of the group, to request a BMW 335I biturbo manual, model 2008, 6 cylinders, since I do not find why the gasoline pump does not turn me on. If I put direct current it works and the engine ignites well, but if the chipo does not work, and I want to check the wiring. Thank you all in advance
