E53/30d is on a distinguished road
2002 M57 30d cant start

Please help my E53 30d i doesnt want to start it only start when i use engine start and it can idle for hours after that, the other thing if i press accelerator hard while driving it cuts off, its got rough idle when driving.

its got two fault codes:
(09F6) Rail pressure monitor on engine start.
1250 Relay pre supply pump (the problem with my relay it doesnt work if i install it normally.. its need to be directed the you can feel the fuel pump working..(i have directed for earth on port (86))

My glow plug module(timer) also doesnt supply power to glow plugs but (but my glow fuse on computer box and main red wire do supply power to it)
(i have three different timer modules and they all doing the same thing no power output)

Things i have have done so far:
Sent ECU to (ECU auto) for a check ..they said its fine:
1. Change fuel rail sensor.
2.Bought fuel sender unit/pump on the tank(its new)
3. Pre suppy pump next to tank (underneath) its also new.
4. Glow plugs all six have been changed.(New)
5. Crank sensor its also (new).
6. Cam shaft sensor has been changed as well.(swapped with a driving car still no start)

Please help i have no clue what else to look for now.
could it be injector leaks?
or my ECU is dead?
