My thought from Page 1 of the thread was an LP system leak allowing air in - you say that the required pressure is met (presumably HP sensor reading?) but given the troubles with getting these engines going if you don't change the fuel filter properly, I would be looking at a temporary analogue gauge on the LP side, plus looking for entrained air with a clear piece of line - air getting into the HP side would still allow you to achieve pressure. (but not sure if there is a bleed on the HP?)

Looks like everyone has run out of suggestions. Now at the point when I learn something new something old is lost out the other side !

Obviously there is no feedback from the garage |

As the FL2 has lots and lots of sensors, I find it hard to believe that there is not a trail of error codes being left (even if they say no further action as above).

2 things come to mind, grey smoke at start up is indicitive of fuel partially combusting. so i would suggest fitting a clear tube on the fuel line to ensure no bubbles of air are appearing in the line. I know you said fuel pressure is reached within 2 seconds, but is this from live data ? if so live data runs behind real time. 2nd I would recommend a compression test. if the compression is lower than the threshold a vehicle will take longer to fire and normally run rough for a few seconds. This is a test that is often overlooked. Some diagnostic testers will allow a compression test by simply crancking in compression test mode , this takes seconds and it measures the cranckshaft rotaional speed per cylinder whilst keeping injectors off.
