Perplexed

Okay gang, here's the problem. As some know, drive kicked out on me a little more than a week ago.

I was getting a CKP error, and have since changed them out. (18" ratchet extension with a swivel does the trick just fine)

Now, can SOMEONE tell me WTH is going on:

The starter cranks the flywheel but doesn't turn the belt side of the motor. I can put a ratchet on the crank (belt side) and turn easily, and can see the flywheel moving on the other side.
No current codes, as she hasn't started since the breakdown.

What am I dealing with here? :banghead:

Thanks, as usual.
