Hi I recently changed my engine in my car but for some reason when I put the negative terminal on the battery it automatically starts cranking the car. But no key in the car and no ignition is on anyone know?

Probably jammed the wires together on the starter motor bridging terminals, or wire at starter on wrong terminal. I would check there first. Safely supported on stands of course.
