2001 FORD TAURUS WONT START AND THEFT LIGHT IS BLINKING AND MAKING A CLICKING NOISE

get your battery checked

Try pulling the fuse for the anti theft system and starting. If the car starts normally, then the problem is with the theft system. The theft system will reset itself after a period of time.

I would check the wires on the starter, it might have a bad connection, also your starter might be bad.

yes the fast blinking theft light indicates that theft mode is activated. you wont be able to start the vehicle until you have the keys reprogrammed at your local ford dealer.

your anti theft is more than likely doing it is their a key pad where you enter a code? If so you need to enter the code that was hard wired to it when you have a bad battery or change the battery the system defalts to the hard wired code, if you don't know the code it should be on a sticker in the trunk I think it is on the hindge to the trunk lid right side!

you have to turn off your anti theft for it to start

If you are reseting a factory alarm...lock and unlock the drivers door with the key. If you don't know the code look under the dash driver side in left corner there should be a black cover with a sticker with a code on it 6 numbers that is the factory code.

Either you may be using a key that you had copied from the original or your chip went bad in your original key. Most of cars now a days have the key censor in the key so if it is the incorrect key it will not start your car or if it does not read that chip it will not start

make sure battery is fully charged and have tested for a weak cell and check out the alternator and the drive belt and if the car has over 40,000miles it needs a tune up plugs wires fuel filter and if all this fails have the timing checked and don't forget the crank sensor to have it checked

Mike. Please be sure the battery is good. and full charged.
OR if you have an other one, change.
