Hello and Welcome to LinuxQuestions,
More important when troubleshooting something is what's found in the log(s). Did you check your /var/log/messages, /var/log/syslog and any particular log that pound might be using for errors when starting pound? Open an extra terminal and tail the logfile(s) with:
tail -f /var/log/messages /var/log/syslog
and start the service again. If pound has its own log configured, then open that one in the tail command to. Post any relevant error messages here. Just 'failed' says nothing.
Looking forward to your participation in the forums. Have fun with Linux.
