I'd check a spark plug to make sure it isn't flooding, but it sounds like you're not getting fuel so you're on the right track. I'd check/replace all vacuum lines before continuing diagnosing. Or at least plugging off all the unimportant ones. Then check that oyu're getting an appropriate MAP sensor and TPS reading. I'd expect either would cause your issue.
Edit: Don't forget the coolant/engine temp sensor while you're at it. That too causes start up issues.
