318 won't crank over- trouble shooting suggestion?

Thanks for the suggestions!! The battery was reasonably new...and I think that adding in the jump start would probably make up for a weak cell, though I will want to get a completely new battery for this car anyway so I might as well get it now.

I'll give cranking it over with a wrench a try! I have never done this before...

...but I assume I will have to pull the fan and the plugs, and get a socket on the end of the crank shaft, right?

From there, I assume I will have to rotate it clockwise while (facing the engine)...is that right?

You don't have to pull the fan or plugs to rotate the engine. Just get a socket on the damper bolt and turn it clockwise. You can probably reach it from under neath if there are things in your way. You'll need a breaker bar or a long handled ratchet but you might be able to do it some other way as long as you have enough leverage.
