Change your default routes on each router to point specifically to the other routers IP address, not just out teh FA0/0 interface. Then do a ping to the others loopback address, making sure you source it from the local routers loopback interface, that should bring the tunnel up.
Remember that the tunnel is only built when traffic is sent, so if you don't do a ping or the like then you won't see the tunnel built.
If it still fails, please run:
> debug crypto isakmp
> debug crypto ipsec
on both routers, try the ping again and send us the output.
