if you have a test light, take a injector plug off, then see if the test light flashes when your cranking it. iirc the injectors flash when the key goes to start to prime it.

a side marker bulb also works, put it in the injector plug, it will flash too like a test light would.

fuel pressure is one thing, is it getting gas is another.

you can also give it a shot of starting fluid in the intake as its cranked, if it fires up your not getting gas for some reason.
