There should be no partial failover.
Either active/passive or active/active.
Do you see failover event in System log?

If firewalls don't see each other over HA1 then both are active and accept sessions.
Shut down one firewall if you can't fix HA1 to get things up and running.
You have split brain situation.

Its no longer in split brain that I can see , but we could restart the passive firewall right now and see what happens. It is trying to send traffice to a router IP that no longer exists

Are you sure that your passive firewall is actually passive and not processing traffic. Just because this unit reports that it's staying in active after the split-brain event doesn't mean necessary that the peer firewall didn't come to the same conclusion. During the 428s where you were in a split-brain event however you would definately have both firewalls processing traffic.

But what would it route to an IP address that no longer is on the PA?

Are the sessions routing to the non-existing IP possibly be tied to existing sessions? Depending on your policy setup it would continue to take that path, or attempt to. If this is tied to specific sources or destinations you could try clearing the session list with a filter for that criteria and see if that clears things up.

could there still be a session related to an IP that was removed several months ago from the PA? It also looks like the synch is still in progress between the two PA's and it seems like it is lasting too long
