P.P.S. i Have since noticed that the cranking figure is quite low. I have just tested one in the yard here and with a good battery i am getting 250rpm with the camshaft sensor disconnected All the best Kev G
Looking at the fuel pressure i assume it is measured in bars, but your icon is in the way if that is the high pressure figure then you have no problem with the high pressure system or injector leak back.
As long as the fuel is >120 bar this will release the injectors to fire. Does the glow plug light come on then go out ( if it is staying on after the engine has started and goes out after 30 seconds then you have 1 or more glow plugs out) if it is staying on all the time then you have a faulty glow plug timer unit.
On the sprinter it is not uncommon for the glow plugs to fail and short to earth so be sure to test them for current draw and not just test for continuity because it's easy to fry the timer unit( although they are easy to repair)they are about £80 Starters are also a concern but normally the soliniod sticks. also what was the other code not displayed i noticed that there were 3 codes but you have listed only 2
