Fitting new diesel fuel pump any suggestions?

My Vectra 3Ltr (54Reg) TDi has had problems starting during the last week . Now it will not start at all. I have checked the fuel filter this is clean but the fuel is at a low level. I have seeked an opinion from the AA and also the the main Vauxhall deal. They both think its the fuel pump. Is it a major job to replace the pump, I and my son have good experiance with mecanical matters.

Vauxhall Vectra Vehicles, Cars Diesel Fuel Pump

Thanks for this . The main dealer has checked the system and apparenly everything points to the pump.
Prior to the car not starting it was very difficult to start when cold

Did they do any testing before condemning the pump?
Did anyone put a gauge on the fuel line to check for pressure?
Is the engine management light on, or has it been on recently?
Did they use 'tech2' diagnostics to check the readings of other components such as coolant temp, crank sensor signal, battery power etc and check for stored codes?
Did the car run ok when it was starting?
A new diesel pump is hellishly expensive, and once it's on you need to haul it to a Vauxhall dealer to get the ECU coded to the car with 'tech2'.
The pumps do fail, but often it is just something else like the crank sensor failing. If that fails the ECU doesnt know the engine is turning so it doesnt deliver fuel.
