I didn't know there is a place to bleed the pump. Which fitting is it?If you are not getting fuel out of the injector lines at injector then must be a clog... I just used a 12 volt 3-5 psi pump. (obviously i used a battery on its own) It will push fuel through the system and make any holes very apparent. Did you bleed the injector pump vent on back of pump?
So you have fuel at the pump but not at injectors... see what happens when you get the pump .
