If you have fuel pressure with the engine cranking, then it may not be the rpm signal, that is a dual crank sensor, four wire connector.
You can take connector loose from one injector, use an led testlite between the two terminals. Have a helper crank the engine, see if the lite pulses. If you smell gas, they are probably working. If you have good spark everywhere and the injectors are working, I'm not sure why the engine doesn't hit? Unless it might be a timing issue, do you have good cranking vacuum?
Do you think it might be flooded? Some systems have a clear flood mode, if you push the gas pedal down while cranking, the computer may shut-off the injectors.
You may need to put a pressure gage on it, to see correct pressure and see if the pressure bleeds off.
