On my '95 960 I had the fuel pressure regulator fail.

Symptoms were a difficult start cold or warm on petrol. More cranking than normal, difficult and lazy fire-up, petrol smelly exhaust, black exhaust smoke... As if partly flooded. Once started it always ran fine.

To find it I pulled the vacuum line off which is easily done with a slight pull as it is not on tight... and got someone to switch the ignition key on. It was dribbling petrol out of the regulator 'nipple' ... this petrol was otherwise being fed through the vacuum line into the manifold.

Got a used one for little money from Braydons who told me they hardly ever fail. Doddle to fit - at least on my 960.

Yours of course may be failed in a different way and so exhibiting different symptoms from mine.
