Seized up from sitting
It's possible, if the car has been sitting for a really long time, for corrosion to form on the cylinder walls and piston rings, locking them together.
Usually, this only happens if moisture has been allowed to accumulate inside the engine, such as it sitting up for long periods of time with the intake manifold or spark plugs removed, and rainwater has been allowed to get in the engine.
Pull the spark plugs so you have no compression, get a big breaker bar, and try to turn the engine over by hand. If it moves, it's not seized. If it doesn't move, you may be able to pour penetrating oil into the bores, let it soak, and break it loose with a breaker bar. & socket on the crankshaft pulley bolt. Rock it back and forth a little at a time to break it loose.
Even if you do this, the old pistons rings will probably no longer seal against the bore properly,and if you do get the engine running, it will likely use oil and have lousy performance and fuel economy. Before long, it will need a proper rebuild.
Oh, and be prepared to open your wallet wide and often with this car. If it has sat long enough the engine has seized up, it will have a whole host of other expensive problems as well. You will need new tires, a new battery, new fanbelts and radiator & heater hoses, you may run into problems with brake calipers being locked up, gummed up fuel in the tank, fuel line & injectors, radiator and heater core problems....
IMO, you are not going to make this car reliable without spending way more money than it's worth.
If the car was left out to pasture because of a bad head gasket, coolant in the cylinders has rusted the piston rings to the cylinders. That's just too bad and there isn't any magic fluid to fix that. You might break it free using penetrating oil, but the rust damage is permanent. The engine will have to be disassembled and machined back to specs.
hi, a Car well NOT seize up from sitting... It could be battery, cables, starter or even the switch. or the old owner lied. and NO there is no special fluid.
good luck

Wow, good luck!! You can TRY removing spark plugs and shoot LOTS of good grade penetrating oil in cylinders, let soak a couple of days, then bar engine over @ crank snout. Hope you didn't pay for this car.
