retorq was according to spec 30ftlbs i beleive.by loosening the union nut at #4 injector i can see there is no fuel delivery at this point.its dry.idle is rough and does not change when the union is loosened.i used a magnetic pick me up to remove the pressure valve components.just so i wouldnt drop them into the never never land of the skid pan.im thinking now that i may have somehow pulled up on the plunger assy and somehow dislodged it.
