Default No power to ignition

This is my problem I have 2004 A8L and rain water filled the floor and flooded my computers,I replaced the computers from a salvage yard ,The battery is fully charged and im getting no power to the ignition, I put key in and turn but nothing happens, no dash lights no nothing, The radio, seats trunk all work fine, The scan tool will not work , needs to be in position 1 but no power in that position, I put a test light to the plug going to the ignition switch and there is no power, only power I have is what you would normally get without having to put in the key and that is it, So putting the key in the ignition gives me nothing it will turn and then get stuck in.
All fuses are good and battery is 100%. HELP!!!!
