If your TBI can you see the injectors spray gas, with the engine cranking? Is there an injector pulse?

If I use a spark plug as a tester, I break the ground electrode off, if the spark will jump between the center electrode and plug body, I consider it ok. You can get a cheap spark tester at the autostore, adjust the gap wide, see if the spark will jump.
