The fuel pump is on the side of my engine visible when I open the normal service door. The injector is on the top and not visible at all. I can see the pump well, but I cannot see the injector at all. I have removed every bolt I can see and the cover does not lift off. . I will have to drain the fuel somehow, or pinch off the tubes connected to it, since the tank is attached to the cover and see what else is holding the cover on.
Ah yes come to think of it, you're right. *Try cracking that union by the pump and crank it. *If fuel comes out, that's not your problem, but if fuel does not come out, that's the cause of it not running and has an air lock.
