Re: URGENT! Major problem! Need assistance!

Ok, when it did crank did it seem to be cranking plenty fast...as usual? If not, and it was cranking a tad slow, it could be not enough charge to turn fast enough to start. Then, once lower it's not enough for the starter to fully engage the flywheel. Low voltage to starter will cause engagement issues.

Check the alternator mounting. sounds like it could be getting loose at mounts. I've had one come off the head before. There had been a helicoil put in one hole that I guess failed which caused the other bolt to shear. How tight is the belt? And, if you put pressure on the belt to take up slack does it make the alternator move? Other than the cold on your battery, maybe it hasn't been charging due to loose alt.
