Don't forget to give an ECM because you use "automata" library and  
it's not obvious ...

You can use

  \path[-,line width=2pt]
  (3) edge node {} (1)
  (1) edge node {} (4);

or

  \path[-,ultra thick]
  (3) edge node {} (1)
  (1) edge node {} (4);

You can add "dotted" option etc... I think you can remove "-" because   
it's the default with edge

but I'm not sure
