What makes my theft light blink?

Just a curious question but what makes my theft light blink? When it does that my car just sits there and turns over and wont start? Tuner maybe? It only does it every now and then, at first i thought fuel pump but noticed it only did it when the theft light was blinking

That's your pats. If you have a tuner on your car take the tune off and flash the stock tune to it. See if that helps I read somewhere that sometimes if it don't flash all the way or properly it can cause that. Good luck

Mine always flashes, but still runs and starts. I re-tuned it and still the same thing.

Mine use to flash for a good bit when I tuned my car but eventually went away. If the car is starting and running ok then no worries. If you want try another key if you have one as a spare and see what it does.

Re: What makes my theft light blink?

If the theft light flashes rapidly,,it means theres a problem with the pcm getting the password from the PATS module..Ive seen a key do that,,you can try a different key and see if that helps,,also theres a plastic round thing right around the key cylinder,,inside the cover,,they call it a anntena..(ford does),,ive seen that on alot of fords go bad..But if the tune makes it do it maybe theres a problem when its loading..I know they tell ya to use a battery charger while your loading it to keep the battery up,,i also read that not to have another vehicle key close to the switch ,,that it could interfere with the signal,,never had that happen personally,,but you never know

Do you have a tilt wheel? If so, when you have the problem, is the wheel up or down? I had the same problem with my 99 but only when the wheel was up... turned out there is a wiring harness in the column that was shorting out only when the wheel was up....
