OK somthings not right here...

Removing and reinstalling the injectors should not kill them in anyway.

If the pressure is 35 instead 1400 and we are talking about bar here then its your fuel pump which is dead. You can't have low pressure on just one injector - its a common rail system, all the injectors are fed from the same rail at the same pressure.

This is what I spsected from the start as you can not run the pump to bleed the system bacuse they have very low draw on them. The correct way is to suck the fuel through from the injector via the leak off pipes.

If you run the pump dry, the lack of any fuel which is acting as a lubricant destorys the tiny clearances in the pump.

This would give you low injection pressures. Which is why the car wont start and if it does start on easy start it also explains the white smoke as the diesel wont combust as the fuel isnt comming out of the nozzel in a fine enough spray to burn.

It also makes sence its not one injector as a car will run with an injector down. It will not, without the correct pressure from the pump.
