Loud noise when I start my Civic sometimes
 

Sometimes (maybe every 10th start) when I start the Civic there is this really loud screetchy noise. My mechanics have been closed the past 2 days so I haven't had the chance to call them, do you guys have any idea what it could be? doesnt sound like a belt, sounds painful really

I am no expert, but I am sure more information will be necessary. Most importantly, where is the noise coming from? Can you get someone to start it up for you so you can listen for where the noise is coming from with the hood open?

EDIT: pumps? pulleys?

Like as in u start it it screeched and don't start?
Auto?
Flex plate could be warped or starter not working correct.

More details needed.
