Wrong fuel pressure and injector/s not pulsing

Do you have to feed it constantly with starting fluid to keep it running or hit it ones and run on its own?

You need to check if the injector/s are working-opening and closing

When cranking engine over do you hear the injector/s clicking -if not its not pulsing could be a dead injector/computer ground drivers.
