Ok, thanks

- injector leak off test was ok. Worst did 14ml/min with cold engine (+2 c)
- according to live data, rail pressure is steady and follows set value.(excluding delayed startting)
-Brand new battery
- If rear end is high enough it will start in 1 second, so I dont think that broblem is pump(s) or regulator??

What abaut regulator? Is it open or closed when ignition is turned off. Is it possible, that rail pipe drains empy if injector return leaks air?
IF Regulator have some basic setting when engine is off (not fully closed), this could be a reason?
Any ideas?

This morning startted perfectly when rear was 30-40 cm higher, outside temperature -13c

No need to wonder anymore. High pressure pump blew out diesel all over the engine room.
