Probably a bad starter solenoid.
it could either be a bad beattery or a bad starter
under the hood on the drivers side in the relay compartment
Remove and replace the starter.
Cranks and turn over are the same thing. It may crank or turn over and not start. If that is the case, find out if it needs fire or fuel and go from there.

A bad starter can cause a Mercury Grand Marquis to not start. A bad alternator or a problem with the security system can be the cause for the car not starting.

If you can hear your starter motor turning but not the engine you have some teeth missing on the ring gear. If you can hear nothing, not even the starter motor solenoid clicking into place, you have a connection problem between ignition switch and starter motor.
Disconnect grd. Wire (black) from battery remove 2 mounting bolts drop down/remove. If you need to move the car hit the starter acouple of times with a hammer to get it to start. Only works a few times!
check your fuel pump relay, and starter make sure the starter wires is on tight, last make sure you put on your fuel pump right red is positive black is negative
Try tapping (not hitting) the starter cellinoid. Sounds like it might be time for a new one. Pick up a service manual at your local auto parts store.
A no start condition where the starter just clicks.
Sounds like a Fuel Problem to me.
Maybe the chip in the key is defective.
Check the ignition coil on the Marquis. Check the crank sensor as well. One of these is probably bad.
Commonly CKP sensor or Starter. What does it do when you try to start it? clicks
changed sterring column changed crank sensor and fuel pump
