800 no crank (no start)

Recently purchased a 2007 800. My key was left of for awhile, long enough to drain the battery and not start. It would try to start (very slow ctank until ultimately it died) So i got a new battery) so i replaced the bettery and now it won’t start. I have a good strong battery, the relays click, the Speedo lights up with no check engine light, you hear the fuel pump turn on. The starter solenoid clicks. If. Jump terminals to solenoid the starter spins Any thoughts?
