So /var/lib/pgsql/9.6/data is where the original install is?
Best guess is that some script is starting the original install and when
you go to start your custom location it fails because the new cluster is
trying to use the port(5432 I am assuming) as the original cluster.
Have you tried giving the new cluster a different port number, say 5442,
and the starting it?

So you either need to change the start script to point to the new
cluster or create a new one for it.
