Cold Start Issues with Ducato 2.8 jtd - Long Ignition Time, No Computer Errors

Hello, I have a problem with my 2.8 jtd. The car is cold, for example, after a night stop in the morning, it starts very hard, I have to turn it long before it starts, no errors on the computer, fuel pressure around 250 bar during start-up, I thought that the injectors were pouring, so I gave it for regeneration, but it did not help, it fires in the same way in the morning , sometimes it starts immediately, and sometimes I have to spin for a long time, it also catches and goes out, then for the rest of the day there are no such problems, it burns without problems even after a few hours of inactivity, the engine does not smoke, has power, the battery is healthy, the starter the same, I checked the masses, only what I noticed was the fuel pre-pump in the tank in the morning as if it would work harder (slower) with breaks slow-fast-slow, clearly audible, it was also changed to a new one, but nothing helped, with the next start-ups this effect is no longer there. Fuel pressure regulator cleaned, O-rings changed to new ones.

No word on glow plugs and spark plug controller. Checked?

here is a flame plug only works below 0

Check the pressure in the cylinders.

The pressure was also checked, there are no excessive deviations 28-29b I have no ideas what can be, during the day it fires almost by touch, the problem is only after a night stop ... in the logs during firing I noticed only that the engine speed jumps during the shooting, e.g. 200 . ----- 0 ---- 180 ----- 0 ------ 220 ----- 0 as if the speed controller was not seen for a long time, not and if it is normal,

So everything points to the injectors. Since there is pressure in the cylinders and the right fuel pressure, only the injector can pour and make it impossible to start.
Unless your timing / ignition is misaligned.

What exactly is the engine, model, year? I'm asking because:

could indicate a defective camshaft / camshaft position sensor.

Ducato 2000 2.8 jtd 128km. The injectors fall off after regeneration with a new Bosch agent, made by a trusted company

this is some clue, I will also look at the shaft position sensor,

Added after 15 [hours] 38 [minutes]:

Hello, the replacement of the shaft position sensor with a new one helped, now it burns without a problem after a few revolutions with the starter, so if someone has problems with morning firing, let them first check the shaft position sensor.

It is strange that the computer did not register a malfunction of the crankshaft position sensor. As a rule, the sensor fails when the engine is warm and starts working again when the engine is cold, but maybe it worked for you.

here he lost the signal as it was cold, as I described earlier from the logs during firing, once he saw the revolutions, once he did not see how hot it was, everything was ok, the position of changing the sensor is cold after a few turns of the starter, ecu unfortunately did not show any error.
