I need you to check a couple things. First, go to a parts store and get a noid light. Most will lend or rent it to you. The light is used to check if the fuel injector is working. Plug the noid light into the injector wire. When you crank the engine, the light should pulse everytime the injector gets power.
If you are getting power to the injector, you may need to remove the injector to see if it is actually delivering fuel to the cylender.
If all is good there and you are getting spark to the plug, you need to check compression in the cylender. If you have spark and fuel, it should fire for you unless the compression is very low.
It sounds like a lot, but it won't take long to do. Check it out and let me know what you find.
If you have other specific questions or concens, let me know.
