Wet the end of your little finger and put it in the spark plug lead on top of the cap. Just kidding. Some auto part stores sell plug wire testers that you can put next to a plug wire and see if it fires, for me, I would switch the number one wire with another of the same length and see what happens.

The only thing that would stop the injectors from firing would be the crank sensor, usually.
Do you have a good OHM meter and know how to use it, if so you can use it to see if your injectors are firing.
You might also spray some carb cleaner into the t/body and then try to start the engine, if it fires up for a second or so, this is good.
