Heres the scoop, the car is having a fuel delivery problem as I have lost power and experiencing drag, stutter ect and basically the car smelling like gasoline and idling pretty rough. The ECU is blinking 16 (injector failure). I was prepared to take it to Honda and this is where some good advice would be welcomed

Honda said they would hook it up to the computer ect but I am kinda concered that they wont tell me exactly whats wrong with it, they said they would hook it up to the computer. Would this be good enough? Right now im thinking along the lines of faulty:
fuel pressure regulator
injectors
fuel pump
It doesn't seem like they would be willing to test out each part individually so... what do you guys think?
