How can you tell if you have a seized engine on a 1993 Ford Crown Victoria?

Answer 1

You will not be able to turn the engine over....... If the starter cannot do it, and you know what happened before, like low oil, or no oil, or something else, then remove all the spark plugs, and try then with the starter, if not, then try to turn the engine over by hand, with a socket and bar on the crank. Having no spark plugs in lets the engine turn with very little compression. Hope its not seized. If it does turn with ease, then look at the starter for the problem, or low battery. Good luck.
