Fuel injectors are electric. When the injector is energized, an electromagnet moves a plunger that opens the valve, allowing the pressurized fuel to squirt out through a tiny nozzle. The nozzle is designed to atomize the fuel or to make as fine a mist as possible so that it can burn easily. I find it hard to believe that all the injectors are bad or not working. How do you know they are not spraying fuel? Have you checked them?

Yes, I have air filter etc, off and when cranking engine see no spray. We very much appreciate suggestions and help. If we add a little fuel directly, it starts right up.
