318 won't crank over- trouble shooting suggestion?

Does the starter solenoid click at all? If it buzzes, it's probably the starter, the solenoid is not engaging properly. If it clicks once then nothing it's probably the battery. Even though you charged it, it may have a bad cell, may need a long trickle charge and/or replacement. Can you swap in a known good battery?

On the mechanical side, can you turn the motor over with the crank? If you can, it's probably an electrical problem.

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?
