Traffic not passing through Pix

I trying to get a Pix 501 up and running, But traffic does not pass yet.
From the router it is connected to I can do an extended ping off of the interface the pix plugs into.
From the Pix PDM I can ping public IP addresses through the Pix Outside interface.
However I can not ping from the private side to the outside, so I think it is a NAT issue.

Please review the config and see if you can help.

Result of firewall command: "show run"

You need to allow icmp in the acl
 access-list outside_access_in permit icmp any any

By default, the PIX will allow the ICMP packet out, but it will not allow the reply back in.

I agree with lrmoore, you have to allow ICMP to come back in.

Is it just ICMP that won't go out or can you not get to the Internet at all?

You might also want to try clearing the translation tables with the "clear xlate" command.  This will clear all NAT translations, so if anything is able to get out, this will break those connections.

This did the trick.
My DNS server has issue with the firewall, But I will address that later.
