I have a 1.x network and 10.
The 10.x is behind a 1600 rotuer and all the rules are open to access the 1.x network, but I cant access it
Is there anything missing on the pix side the 1.x network that could be stopping access to the 10.x network here is the pix config

Since you have 2 private networks one on a router side and one a pix side, you need to have rules that allow both through, so inbound rule and outbound rule for the respective interfaces. Then you most likely need to make sure that you do a nonat for the two subnets so that their physical IP addresses are passed back and forth from subnet to subnet and not using the NAT'd outside pix IP address.

By default the pix will nat everything unless you tell it not to.

Thats all you really need to do and it should work.

If not, can you provide a general diagram of how your network is connected..

Thanks
