Check all the ground connections. Make sure they are tight

I just spent the las two weeks fighting this issue with my new build. Turned out it was a ground strap from the firewall to the back of my cylinder head. Does it seem like its shorting when it won't turn over? If so, you can turn the lights off and try and see a spark when it shorts. Thats how I found mine. Good luck
