If you put a volt meter on the battery and it reads 12 volts before you cranked the engine and it drops to 10 volts or less when you crank the engine, this indicates you have a bad cell in the battery and you should replace the battery because it is not holding the charge. The loud click sound coming from your starter is because you are not supplying enough voltage to energize it.

I looked at info for your security system, it is starter motor disable. I didn't see 06 ford Taurus in my database, so I looked at 05.
Battery has a full charge and battery connections all good?
We can usually do some tests to see if starter motor will crank the engine, but, if the security is the problem, it still won't start.
You can check for applicable trouble codes? Try a different key?

If that happens and your on the high way or on the road have a extra battery and the jump starter in your car that way when your car dies on the road you will have the jump stater plugged in the extra battery in your car. Now your probably asking why do i need a battery and a jump starter in your trunk, well if your car dies there is a most likely chance that people will stop and help. Another reason why is if your. Car dies you can plug the jump starter to your car and the other end to the extra battery and try to turn on your car and that should work

The battery may have enough juice left over to make the lights work but not enough to turn the motor over. If the battery is discharged, you probably need a new alternator. When the alternator goes the car will run until the the battery doesn't have enough juice to fire the motor.
If the motor will turn over but just not fire, it's an electronic ignition problem.
If the battery has full power and the starter motor turns but the motor won't turn over, then you have a broken timing belt.

the alternator may of went bad and stopped charging so the car died when the battery went dead. Charge the battery and test to start with. Are you saying wont turn over ot turns over and wont start. If it turns over and wont start then it could be several things. Will need to get it diagnosed to be sure

maybe you should have the battery cheked and all the cables and the soliodes

Check battery cables. Clean and replace bolts that hold them on.

when alternator warmed up it would not put out proper amps. replaced and works fine.
