If you have got the low pressure rail warning then its as darren said, the pressure sensors in the rail, I have come across 3 other cars in the past 3 months that have had/having these problems.
But also keep an ear out if the intake pump is priming while it has a failed/delayed start? there has been 2 cases I worked on were the TIMP randomly wouldn't trigger the pick up pump and prime the fuel system, leaving to delayed or long cranking before starting
*fuel filter is on the low pressure side, so even a semi blocked fuel filter won't give of a low pressure warning once, unless its completely blocked and preventing flow, which the car will not run as the high pressure pump would not have enough fuel to maintain pressure (under 2000psi and injectors stop firing)
There is a CRD facebook page where problems like this are posted,

Injectors out of spec...Yep have to agree.. seeing how that's what I have had to just replace, not cheap either, but I do have 220500kms on the clock so I guess I cant complain too much. :-\
My symptoms were slowly getting worse.. ie. longer and longer cranking before starting .. then finally it would just keep cranking sort of trying to start but would not fire. Funny though as soon as I got tow started by a mate it fired up pretty quick.. but it had a misfire between 1500-2000rpm.
