Could be the fuel pressure regulator along the passenger side fire wall on top. They wear out over the years. You can buy a rebuild kit for 10.00 , or a new one cost 20.00.

Try putting some fuel in the air cleaner and starting the engine. If runs for a few seconds and dies then look for vacuum leaks. Or it may be time to rebuild the carburator.

If it still does not want to fire up and run have a compression test done, timing chain may have jumped.
