Excuse me for dragging out this thread, I agree that slightly longer cranking is not an issue but after engine has been stopped for several days we are having to crank so long that the battery gets weak and the starter very hot, so far it has always caught but we are in very warm climate, I am cooncerned that one day it may not start and on a Yacht with only one engine this is a big problem!
It has been suggested to me that I should run the motor with the rocker covers removed to see if there is a high pressure oil leak at one of the injectors? and that I should replace the HEUI pump and injectors? both very expensive options.
Runs perfectly once started but previously for over 10 years this engine has always started with less than 5 seconds of cranking, something has changed?

ECM Serial Number: 9KS01841
ECM Personality Module Pt. No: 2182970-00
ECM Personality Module Date: Jan02
Engine Stopped Injection actuation pressure 270 PSI
Cranking only slight pressure increase (276) until engine catches
Idle (700rpm) 1600 PSI
Control Valve disconnected Alarm: "Injector Activation Valve Current Below Normal"
Pressure drops to 700 PSI idle unsteady.
Reconnect Control Valve, idle steady, pressure rises to 1600psi.
Is it possible we still have air trapped in the HEUI ststem that is taking time to compress, or oil is draining back to sump?
Did catch much quicker this time because it was run yesterday, seems the longer it is off the slower to start.
