Check the battery terminals and cables. When your relocate a battery that far you need larger gauge wires to carry the proper amount of power. Also when you say you go to start it and nothing happens, that could indicate a starter solenoid issue. The "starting wire" you're talking about is an orange wire that comes from the dash connector to the ecu. Its an orange wire and basically tells the ecu to cold start the engine. Mine was not hooked up when I got my car and I had no power coming from the dash connector orange wire so mine is on a switch from the battery (it needs 12V). The wire is orange on the ecu as well. Test if thats getting power. Hope some of this helps.
