Could be that the computer is not receiving the ignition reference signal therefore its not energizing the injector/s or a problem with drivers in the computer or power to the injector/s-

Did you check injector A and B fuses 15amps, also check the camshaft position sensor in the distributor this is the one that synchronizes the injectors-
