its got a new fuel pump so could it be the filter or the fuel lines?
its got a new 3 bar..
It could be anything that will not allow 350bhp worth of fuel to flow from the fuel tank, through the pump, through teh filter, through the lines and up to teh fuel rail.
It also must do so at 5bar, so the regulator is also a distinct possibility. Have you got a picture to hand of your engine bay?
Do you know what your fuel pressure is set to?
