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.

Why would a 1999 Mercury Grand Marquis start but then stall right away?

Likely the fuel filter is clogged so you need to change it. If you can keep the engine running by pumping throttle a few times at start up, and then it runs, check the filter; cost about $10.00.

Make sure the air filter is clean. Fuel can't burn without air. Also try replacing the spark plugs.


1989 mercury grand marquis battery is fine and so is alternator why won't it start?

First off, does it turn over (crank) and not start? If it does and the motor sounds like it should start and it doesn't then check and see if your car is equipped with an ignition module, which I'm pretty sure it does. If it has an ignition module, replace that and it should solve your problem. Ignition modules are inexpensive and easy to install.
