DONT SHOUT

Its probably overfueling due to cold start not working properly.

Are the injectors the correct opening pressure as although they are not coded etc like modern injectors they still need to be working properly 130 bar rings a bell

Yes.

I've never seen a stuck cold start cable cause excessive white smoke like you describe. The cable works via a wax stat and they get lazy as they get old, I disconnected the cable from the pump on my car and it still started perfectly well in all temperatures.

Does the car struggle to start or does it start ok just with the smoke?
