Nissan X-Trail T30 2.2 Di 114 hp - problem with ECU (Hard start)

[Codelove]

There is a Nissan X-Trail T30 2.2 Di 114 hp, 2003. It has a really hard start. It needs like 5 minutes to crank.

I found this nice thread about the same car and same problem: https://www.picoauto.com/support/viewtopic.php?t=20561

What do you think based on my live data?
I think it has enough "Actual CR pressure" to crank (40-48 Mpa). The guy from that thread said that his main ECU in the glovebox was not sending signals to the second ECU, so the second ECU could send signals to the injectors.

Problem solved. It was the connection between the ECU in the glovebox and the ECU in the engine, just like the guy on that thread. We sprayed the jacks with a contact spray, and it was all okay afterwards.
