I've had a engine seize on one of my cars. All might not be loss. Pull your spark pugs, Make sure the oil level is where it should be. Put a big fricking wrench on the crank bolt and turn the engine. If your able to turn it, good. After that I don't know what to tell you.

1989 Dodge Raider 3.0L with 5-speed.
In limbo of what to do with it.
