Try unhooking the pos =neg battery cables and letting it sit for a little bit, then try again.
Answeri got the same problem.. with a 2000 expedition... darn theft light blinks real fast and the car wont start. help!
Not enough information regarding why the car won't start but as to he security light; it's always blinking when the engine is off.
I believe that when the PATS theft light is blinking RAPIDLY it is because you are trying to start the car with a non-PATS coded key. If it is blinking every couple of seconds SLOWLY, it just means the system is monitoring the ignition.
WE had the same issue with our truck. Its a sensor in the ignition that you can't change or by pass. Its an electronic chip sensor. It took 6 trips to the dealer to get this found and fixed. Good luck
change the blue box maybe.
It COULD be the fuel pressure or if the theft system light on dash is blinking,it is that.
it mean there is a hydraulic or electrical fault on the transmission
It's telling you the revolution sensor is not matching the revolutions of the engine. The ECU takes over and cuts current to the AC when this happens and the ac light will start blinking. A turn the AC of then turn it back on and it's not blinking tells you the problem is going to lead to no AC if you don't get it fixed.
That depends on when it's blinking. If it's blinking rapidly when you turn the key on, there is a problem in the anti-theft, and the truck probably won't start. If it's blinking every 3 seconds when the key is off, that is a normal condition. It's telling you that the system is armed and ready.
