I would check the wiring as well.

When I got my '85 900T 16v (for $188) last spring I had to replace quite a bit of wiring in the engine compartment that had deteriorated and crumbled off. I also had to rebuild the distributor, splicing a known good Hall Effect Sensor in.

When I got my '88 900TC (for $300) in September, all I had to do to get it running was hook up the Turbo Pressure Transducer, it had somehow gotten disconnected. When the PO saw this he was pretty upset since he had sold it to me cheap because it didn't run and I was sitting in his driveway when I found it. I hooked it up and drove the car home.

A bad overboost switch will cause the fuel pump to shut down, you can get around this by jumping fuses 27 and 30. Since you said you have fuel at the spark plug, this is not likely to be your problem. The Pressure Transducer however could be, as it will cause a no start just as you describe (at least it did on my '88). To get to the PT and the overboost switch you should go ahead and pull the lower dash off, it is really pretty simple to do.
