Well, the car wouldn't need to be junked, and you can source an L61 pretty easy. They came in the Cavalier, Sunfire, Grand Am and first 2 years of Cobalt, although I'm told the Cobalt's L61 is different.

You need to get the water out of the cylinders... I'm not sure how you can do it, considering that the Ecotec is dual cam and has the spark plugs in the center instead of the side, but you probably flooded the whole engine. It may still be salvageable. What I wonder is if your PCM fried or not because a bad PCM will also make the engine click but not start. My friend fried his on his Stratus after a battery change. Turns out it had an electrical problem. The car wouldn't get any fuel.

With that said, lets start this at a basic level. Can you hear the fuel pump prime? If you can, then we might be looking for issues between the electrical and under the hood. You would then have to check the fuel pressure in the rail. The goal is to eliminate fuel problems first and work to the worst of the possibilities.

Also, if you can get the starter out, take it to Advance Auto or Auto Zone. They can test it for free. Take the Alternator as well. It may give you problems because alternators and water don't mix.

If everything is a dead end, then I'm betting the PCM fried when it got washed in the flood.
