Technical Ducato 2.8 dies when accelerating

[MARIOJS1965]

I have a Ducato 2.8 JTD 2009, a repair service was done on the diesel high pump, then it was necessary to repair the starter motor as well. It starts and runs in neutral, but when accelerating it dies immediately. It's been 3 days since the mechanic has been trying to identify the problem. What can it be?

As the 2.8jtd was not an option on the x250 model, which replaced the earlier x244 in 2006, I am struggling with the mention of a 2009 2.8jtd????

The description of the problem suggests fuel starvation, and given recent work on the HP pump, I would tend to suspect the fuel pressure regulator. However if rail pressure was not correct, I would expect an error message.

I was guessing the odd age and engine was due to the region vehicle OP is ?
When piggy backed on to another thread I queried whether cambelt timing was disturbed and suggested checking that first to be sure even though pump is common rail.

You will probably get a better response starting a new thread on Forum as more people can read it.
However I would first check nothing has been disturbed on the cam belt timing side, I know that the High Pressure pump doesn't need timing it's self but that doesn't mean the rest hasn't been disturbed also being common rail injection and electronically controlled, has the crankshaft position sensor or the plate it reads from to time it properly been damaged.
Finally if all that is OK I would throw the "serviced" pump back to who ever did that job. Assuming there was no other underlying problem before the pump was disturbed."

Yes I did consider possible regional variations, but unless the engine type is confirmed, difficult to give appropriate advice.
One other possibility that comes to mind is whether the engine has EGR, a possible option on the 2.8jtd. If yes then what happens if the vacuum line has become disconnected? Vacuum and HP pumps are part of the same assembly, and lack of vacuum to the brakes may not be apparent, if vehicle not driven
