V50 Engine 2.0D : Crank no start after sitting for 2 weeks

[rich_f]

Hi all,

My 2006 v50 2.0 diesel will not start after having sat for 2 weeks. The battery is almost new and is fine - it didn't did during that period. It cranks but does not fire.

I had this very problem a couple of years ago and tried all the usual things to get it going again and eventually it did start, and has been fine ever since, apart from sometimes it hesitates under acceleration in the few minutes after a cold start.

I had problems with air in the fuel line at the start of the year but that went away when I changed the fuel filter housing and has been fine since (apart from the occasional hesitation mentioned above).

Since the non-starting after sitting for a while has returned, I'm wondering if it is a problem with 1 or more injectors not being able to maintain the hight fuel pressure while the car isn't running and it all leaks away, allowing air to get up by the injector itself - is that a thing? (I don't see any air in the fuel lines).

I'll continue to try to get it started but I'm now concerned that the problem will return again.

Anyone got any thoughts on what it might be and what I might need to do to fix it?

Thanks,
Richard
