Saab 9000 running problem lots of black smoke, no power

Hi,
Help!!! Can anyone please provide any sound advice on this 9000 tech problem?
I have a Saab 9000 Turbo S - (UK version) 1990;
The car has run fine for me for 6-7 years, then suddenly no power, lots of black smoke and running very very lumpy!!
I have checked the AMM by trying a new one (expensive!) Tried another fuel pressure reg; The DI cassette; The AIC;
All vacuum hoses and intake hoses are fine and still the problem persists. It will start ok - run for 30 secs trying to sort itself out, but then dies because the fuel is so rich; It is running very very rich - hence all the black smoke. I checked the plugs - they are not oily, just sooted from the rich mixture. Air filter is new.
I thought my Fuel system was a LH 2.4, but the test pin under the bonnet is live +12V, so I have a feeling that it may be a LH 2.2; Thus I cannot easily get at the fault codes, unless someone can tell me how.
I am about to check the fuel pressure and the timing of the injectors, however, if anyone can provide me with any additonal info or a pointer in the right direction to solve this problem - it would be very much appreciated!!
Thanks,
Neil
