1996 Pontiac Bonneville 3800 No start Getting

It sounds like you were the victim of the infamous 3800 plastic intake manifold. They have a serious history of leaking coolant into the valley and on to the oil pan. If you didn't catch this in time and ran the engine too much with coolant in the oil, you may have destroyed the engine. If you cant move the engine by hand with a socket on the crank bolt, it's likely too late.

Here is a TSB on the subject.

If you have liquid in the cylinders, you can have what's called "hydrolock" because liquids can't be compressed. That is a possibility
