Auto parts stores have a tool called a "noid light". You plug it into the connector for one of the injectors, then watch if it flashes while you crank the engine. I don't know anyone who has ever used one, but that is their purpose.

If you suspect the injectors aren't firing, that is very uncommon by itself. Be sure to check for spark too. A lot of people get hung up on the first thing they find missing, and forget to look for all the other related symptoms.
