Silenoid clicks but wont engage the fly wheel

When I Turn the key you can hear the solenoid click that’s it. The motor doesnt turn over or anything. I was able to get the motor to start when I jumped it over the starter itself. that was a few weeks ago . Today I went out and nothing again. I tried jumping it over the starter again and you hear the starter spin but will not turn the motor over. I was able to turn the motor with a 3/4 inch socket and breaker bar motor spun fine. I replaced the starter that didnt help. I am in need of some assistance. Thanks
