Why would no spark or power go to the injector?

Answer

The crank sensor would definitely cause no spark. As for the no power to the injector it might actually be the ignition controll module(as odd as it may seem). I was just talking to a mechanic freind due to a simalar problem on an `88 Grand AM (no spark and no signal voltage at the injector)and he said that If the ignition module goes that it shuts down fuel delivery too. Hope this helps you out.
