If the engine fails to rotate, the problem may range from a worn strter to broken engine component.
In your case, this happened while you were driving.
- Attempt to rotate the engine by hand. Use a socket and ratchet on the cranksaft pulley nut and attempt to rotate the engine trhough two complete revolutions.
If the engine cannot be rotated through the two revolutions, the engine may have internal parts breakage. The broken components may have lodge into the cylinder block preventing the engine from rotating.
In addition, engines with interference fit combustion chambers may have valves imbedded into the tops of the piston if the timing chain (or belt) slips or break. To verify this, remove the valve cover a? Or the oil pan and perform a visual inspection.
