It doesn't even start before it throws the code yes its is doing the same thing as it was before the battery was changed.
If it doesn't crank or try to start, double-check the wiring between the battery and starter, also the battery ground cable.
Also, find wire 56 that should go to the starter relay. When you attempt a manual start you should see battery voltage on this wire during cranking. Do you hear a click from the starter relay?
