your config are ok. can you try to ping from any ip address in range of inside address.

I cant reach the inside address , I think is a problem of ARP , maybe I have to clear ARP in some switches .
What do you think?

clear arp best is do in change control all arp cache entries will flush. could be a downtime for a 2 to 3 secounds

Yep, the vlan 602 is assigned to that range 10.54.119.128/26 . Po5 to FW1 and Po15 to Fw2 , I will try again but how this is a production enviroment I wanted to make sure that the config is Okey
