Check fuel pressure at the filter with an adapter, or check injector squirts fuel with crank position signal present and adequate fuel pressure. (they wont squirt with too low a fuel pressure). With key on the fuel pump will run a couple seconds to build up pressure but that doesn't mean you have good pressure at the throttle body. Correct pressure is 10-13 psi if I recall. If you only have half that injector won't squirt. You can check if engine will fire with just the slightest amount of starter fluid, and I mean SLIGHT. If it fires even briefly you know it's a fuel issue you're having.
