Keith let asume that you use yum to install pure-ftp and you use---and you
did not use nothing else to configure pure-ftp than chkconfig,

-----yum install pure-ftpd

now after that you create the system startup links

----chkconfig --levels xx pure-ftpd on (xx =whatever level you use)
or
----chkconfig  pure-ftpd on
then or just reboot OS
----/etc/init.d/pure-ftpd start

now check if is listed

----chkconfig --list pure-ftpd

then you command will be
----/etc/init.d/pure-ftpd stop


now using chkconf you will remove the startup link

----chkconfig --levels xx pure-ftpd off
or
----chkconfig pure-ftpd off

now that should do it,

good luck
