Ford Focus TDCI 1.8 Mod 2008 does not start

Hello little boy, I wanted to consult them I have in the workshop a Ford Focus TDCI 2008 model I can not encrgent the problem, it starts but it is not underway. I discovered that current does not reach the fuel pump therefore it has no pressure in the Common Rail. My question is where the pump relay is since the fuse is in good condition I have to suspect the relay that is not working correctly
