Can anyone shed some light on this?
Nothing else was disturbed or altered during this process apart from the fuel rail. The injectors were ultrasonically cleaned and re-installed with 8 new seals. I've owned the car for over 4 years and it's always started immediately or within about 3 turns.
So; consistantly fine before and now consistantly ~10 turns before it catches.
It's worse when the car's been sat for hours/days. Doesn't really do it after a few mins.
Is the fuel/fuel pressure being slowly lost from the rail?
Is there any kind of non-return valve as part of the fuel rail or it's associated pipework?
(Does the fuel pressure regulator do this?)
Could any of the new seals be letting air past? Would this even cause the symptoms?
What's the current economic situation in eastern Bangladesh?
Can it be anything to do with the actual cleaning of the injector units themselves?
