Default HELP! Just put my new motor in and no crank no start!

Hey y’all I need help, I just finished putting my new motor together, put it in today and boom no crank no start, I’ve got a new starter in and all my fuses are good, I turn my key dash goes dark after a couple seconds, turn it to start and I can hear my starter relay click, and nothing happens, I’ve checked all my grounds and I’m about to pull the intake off and check the power wire, any ideas?

Confirm the battery's state of charge. Charge as necessary.

The notor turns over by hand before and after installation?

Your battery is weak. It needs to be fully charged and load tested. Most auto parts stores can do this for you.
