Sounds like a secondary air pump. On the next start up have the hood open and try to find out what is making the noise. It will help us out...

It would be best to stop by and have an experienced technician listen to your grinding noise. Maybe your starter is going bad. It is hard to tell with out actually hearing the sound.
