I don't understand the downvotes too. However, you can try this:

Import-Module WebAdministration

gci IIS:\Sites |
     where state -eq 'Started' | 
     select -ExpandProperty applicationPool | 
     % { Start-WebAppPool $_ }

It seems like you don't have to check whether the applicationPool is already started, but you can adopt the script and check the status using the Get-WebAppPoolState cmdlet if you think its necessary.
