2000 Lincoln LS won't start

Based on your description the vehicles engine may have seized. This engine fits very tightly under the hood so any access will be snug.

Using a socket of the appropriate size and 1/2" socket wrench, attempt to turn the crankshaft clockwise. It should be fairly difficult but become looser and tighter as it is turned. If the engine will not turn 2 full rotations then it will have to be replaced.

Please post back if this helps or if further assistance is needed.

Good luck,
