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?
