New member here. Just read this entire thread as I'm picking up a 1983 Ford Futura with an I6 200 tomorrow. I found the emissions and vacuum info interesting and complex. I never ran across a vacuum or emissions issue that caused an engine to stop with no spark afterwards. Seems odd that a vacuum controlled switch or selionod would not reset or allow successive starts. Anyway, glad I found this forum and look forward to learning more about this platform. Certainly going to read all the threads about deleting the Ralph Nadar crap.
