If the external VN is created through UI and network deleted through neutron, then see following error (there are not ports in the VN):

I guess the floating ip pool is referred by project. When floating ip pool is created from UI, was it made to refer to projects?

IF yes, that reference should be deleted before trying the neutron-net-delete.
