TDC adn CKP are ok?

[diagnoza_auto2000]

What you mean TDC and CKP?

What you mean TDC and CKP?

top death censor & crankshaft censor..if are ok

Some time ago I had problem with some Sprinter with same engine and EDC15 engine management system. Had changed that solenoid with no result. After checking all things, it's turned up to be ECU fault. Then I rang Mercedes dealer and asked about reprogramming ECU with software version with no fuel shutoff valve and van went to them. After they did reprogramming, fault was still there....was messing after that with that van and after reconnecting the ECU fault just dissapeared. So...it's driving nearly year with the same ECU with no problems.
Hope this helps.

Well m8 , if the error code begins active after ignition is on, you have to check wires, or ECU . If the error code which by the way could deleted only when the vehicle is warm and motor is working,
and the later appeared on again, I think the problem is in the high pressure pump

It is 100% the high pressure pump,Master Andrew!
He just need to do some tests and to understand it clearly!

Sometimes engine ecu fails,..but it is not so common!
The wires could cause the troubles but not so common too!
But the high pressure intake little 'piece of shit ' could make you very nervous ,swearing around all the oil /fuel companies!

Thank you all for good answers,sow how i see can be Ecu or High presure pump.
How can i some tests to be sure wich is the problem exactly.
But for exemple :
I erase the code,and then the car its working perfectly,i can drive how much i want but if i stop the engine 2-3 times DTC will come again,EDC light too and car go in lip mode(no more then 3000rpm)

I use Star Diagnosis for comunicate withe the car,but its a 638 model and its working on HHT and you can not see there sow many thinks.
Thank you again

There are some files from uncle Robert. Not a lot, but hopefully some help. They are Microsoft XPS files, needs XPS viewer. Opens in windows Explorer.
This is not easy job. Quite difficult to suggest something. I would start from wiring checks and then from cheapest option.
