Answers :

If the motor is hydro locked then it has a coolant leak in the cylinder head or intake. The gm 3.1 and 3.4 are very well known for issue. If the batt is fully charged and the engine will not turn over that probably what it is. It can be a very costly repair so first check the oil if it looks like a milk shake or has white streaks in the oil then sorry but motor done and not worth fixing it.
