(you said you had fuel pressure)
Why didnt he just put a oscope on the cam sensor? ... The ecm commands the injectors and if you have spark you likely have a working crank sensor. ECM sounds likely.
someone said there are fuses for the injectors, I am going to have the mechanic check for fuses, I'll also say something about the ecm.
