I saw what you replaced, did you do any testing? Key on engine off, use a gage and check fuel pressure? If you have the spider fuel system, it is noted for problems. The poppets valves are noted for sticking and fuel pressure is critical.

If it isn't a fuel issue, then engine cranking, visually check for spark at the spark plugs. Also, check for injector pulse.
