So if I am understanding correctly, it will crank when the belt tension is released? I would guess that something belt driven is seized. Take the belt off, and spin each pulley by hand. I would speculate it is the alternator, or a/c drive pulley, but check them all. The squealing that you had may have been an early warning sign of a belt driven accessory failing.

When the engine is cranking, the crankshaft pulley will rotate. It should not have any movement otherwise, and you probably will not have enough strength to turn it by hand. If it still doesn't crank with the belt removed, then you would turn the crankshaft by the balancer bolt(19mm) to see that the engine will turn.

If it cranks without the belt on, there has to be something seized. You turned all accessories, alternator, a/c compressor, power steering pump, idler, and tensioner?
