1998 Ford Mustang V6 Two Wheel Drive Automatic 100.00 miles

I have a 1998 ford mustang. For a couple of weeks it was having a hard time starting. Once it started it drove perfectly. I went to start it today and it will not start. It sounds like it's starting, but it won't. I have no idea where to start. Someone thought that it may be the fuel injectors. Do you have any idea. Thank you so much for your time.
