Surf 3.0 Starting Problem

[B Aston]

The vehicle was working fine before christmas (no issues), tried to start it over the holiday and although it cranks over it wont actually fire. upon inspection the glow plug lights do not come on and it seems as there is no fuel getting to the injectors. I have checked all the fuses and relays which appear to be ok, is there a test proceedure or wiring diagram for checking the glow plugs and the fuel cut off solenoid etc.

Could this problem be related to Immobiliser, ECU, Dodgy Wiring, Inertia switch or some other random thing on the vehicle.

Any advice would be greatly appreciated.
