trust me its a bad harmonic balancer. it is bolted directly to the crankshaft. if it was more than just the harmonic balancer then your engine would have blown up..

Engine is making really hard knocking noise when running. Once it starts it shuts off moments later. Now it just hums and wont turn over, I havent put a socket and ratchet to it to turn the crank yet.

your crank shaft must have broke. there should be absolutely no side to side movement of the harmonic balancer

But why would the pulley and harmonic balancer move side to side on the outside of the timing cover? I understand that the in and out could be the thrust bearing but the side to side wiggle with the bolts tight confuses me beacause it does run. So its a little hard to believe that crank shaft is broken there because if it was why wouldnt the harmonic balancer and pulley fall off?

Thank you for all of your help. I figured that this may have been an internal problem. I have to pull oil pan and take it from there.

Thanks again.
