Try below 2 options -

1. Check if "/var/run/ambari-metrics-collector/" directory exist and is with permission ams:hadoop

If YES. Then go for option2.

If Not try creating directory and check if AMS startup works.

2. Delete AMS service and its components from CLI also -

rpm -qa|grep ams

-Remove all components of ams

And reinstall AMS.

Let me know if that works.

Also please share new logs in text file attach. Its easy way of formatting logs to be displayed at remote end.
