Please can anyone advise.
When I turn the starter motor to start the car, it takes ages to get the engine going. Sometimes not at all.
When the engine is warm there is no problem

There is a previous history of injector pump problem - i had a replacement one (second hand) put in.

The mechanic also put in a set of glow plugs (new)

I am at my wits end with the car. the problems ongoing for 9 months now.
thanks and best wishes
Ian
