If the needles are all crispy, its in bad shape. I imagine you let it get too dry before you rescued it. Do a scratch test on the main trunk. If, when you scratch with your finger nail, the tissue just under the bark is green, your tree is alive. If it doesn't scratch or is brown, its dead.
If you find life on the main trunks, try to scratch branches next. Araucaria are different from other conifers in that they will grow new branches if they lose the old ones. But your tree will never look the same again.
