Most vehicles have power to the injectors any time the ignition is on. The computer sends a ground to the injectors to fire them. So if you check the ground when the engine is not cranking or running it will show power on the ground side. Same with the ignition coil. Use a Noid light or make a light usinging any 12 v bulb. Plug the light into the injector plug. It should flash while cranking. If your not getting any injector or coil pulse. Check your scan data and see if your getting a rpm. It won't be much, maybe 150 while cranking. If not you may have a bad crank sensor.
