Hello I have a Volvo C30 2.0D 2008 at 60K. Lately its not been starting first time in the morning and also if I have driven it for up to hour then leave it for up to hour, come back and it wont start. If i leave it on the second key position for a while, it sometimes starts after a few goes.
when it struggles to start it turns over but doesn't catch.
The battery is 4 Months old.
Recently had a new alternator and starter motor.
Glow plugs are good.
Has anyone had a similar issue

 

injectors want cleaning? happens to me every so often and i just put injector cleaner in the fuel and its fine
