Car cranks but will not start?

You stated that you have spark and fuel pressure, but it cranks over, but does not start. If this were my car, where would I start? I would confirm that there is spark at the plugs. Use a spark tester (can get at any parts store) or use a screwdriver and put it in the wire and check if it sparks to a ground, like the valve cover nut. If there is spark, I would confirm not only do I have fuel pressure, but that the pressure is within specs. You need to attach a fuel pressure gauge to the fuel rail and see what the pressure is. If you have both spark to the plugs and fuel to the cylinders, then check to make sure the wires were installed properly when the distributor was replaced. If you have spark and fuel, car should run. Start with that and let me know.
