Ok so I just swapped in my new motor I unplugged everything but the starter I just let it hang down instead of disconnecting it well I put everything together and I get nothing when I go to start it also notice that my radio powers off and on on it's own anyone have had these issues before Could it just be the battery ?

 

Ground is loose.

 

Which ground would that be

 

Battery negative to engine, engine to terminal on firewall, battery negative to starter. Just check all your connections. Your radio turning off is a warning for a loose ground. The starter pulls all available current through another, smaller ground that isn't meant to handle the current to turn the engine over.
