A Noid Light is a good cheap way to find out if you have an injector problem or an electronic problem.  Unplug the harness from any injector, plug in the appropriate noid light and crank the engine.  If the light flashes, you know the computer is driving the injector and you can focus on injector/fuel supply issues; if no flash you focus on the computer and the handful of sensors it needs to derive injector pulsewidth.
