Could be any number of things. I would start by checking for vacume leaks, have found the rubber seal on th ebulkhead to brake servo can be iffy and pipe that goes to underside of inlet manifold. Without having the car in front of me it's rather tricky to offer much.

Turn ignition lights on but don't start it, after about 20 seconds the throttle body should start whiring while it calibrates itself. once it goes silent try to fire it up.
