I think I have solved this one. Probably operator error rather than a fault with the 945.
It seems that this sort of problem has arisen before in 940's of this vintage, found out through the UK Volvo forum.
The issue seems to be the 5th injector - the cold start injector. I believe this was deleted by Volvo shortly after 1991 as it was causing problems. Multiple starts on a cold engine cause fuel flooding. The solution is to hold the throttle fully open and churn the starter. The engine will then start with a rush once the excess fuel is dispersed.
This works for me.
The lesson is - don't do multiple starts on a cold engine if it has the 5th injector.
