I recently replaced the ignition lock mechanism on my land cruiser. Since then, the vehicle won't start, it just makes a clicking noise. Also, we tried a socket and break over bar with a pipe over the break over bar as well, tried pushing it both ways, with no luck. The vehicle was in neutral. Its my conclusion that the engine has completely seized up. Any Idea what would cause this, or any hints or helpful info on what would cause this, or how to fix it? It would be greatly appreciated...
