So you used a gage and checked proper fuel pressure? If you have that spider fuel system, koeo, 60--66 psi. Engine cranking, you have spark at all plugs? You have fuel injector pulse? Any applicable trouble codes? You have cylinder compression?

Do you have fuel injector pulse? Spark at all plugs? The dist, rotor turns when you crank it? At the moment, I can't think of anything else? You could use a scanner that shows live engine data, see if you notice anything. Even if it won't start, you can get some data by cranking or key on.
