Hello and thank you for your question,If you are sure you have good spark to the spark plug as well as good injector pulse then the next step would be to remove the spark plug and run a compression set. Has that been done?
Okay you need to be sure, as you know you need good spark to the spark plugs, injector pulse , proper fuel pressure and good compression. If you are sure you have all of these then the cylinder should fire. Did you actually run the compression test?
You can check injector pulse with a standard 12 volt test light. Place the test end of the light on the power side of the #2 the injector connector and ground the other end on other wire and cranking the engine over. If you have injector pulse the light should flash. You can read fuel pressure with your scan tool by looking at the data stream.
