Theft Light Flashing! Car won't start!

My buddy has a 2001 Gt Auto. It's been down for a few months now, he said he was driving home and out of nowhere the car just shut off and when he got to the side of the road, it wouldn't start back up, and the "Theft Light" was flashing like crazy, all the car would do is turn over but never start. I've looked at the car and I have NO clue what it could be. He took it to a very well know shop and they refused to mess with it or even diagnose it, they said that they don't deal with that kind of thing. And now after sitting for a while, the car won't even turn over anymore, and yes we made sure the battery was charged lol I've checked all fuses and we swapped out all the realys from my 99 Gt (same engine basically) so I know they were all good relays, and the car still kept setting off the theft light and not starting, now it's not even turning over. I'm lost.

He wants to have Ford look at it, but they charge quite a bit and he really doesn't have the cash to spend at the moment.

But I have never heard of this or experienced it, so ANY advice would be appreciated.

Re: Theft Light Flashing! Car won't start!

alrighty there is a few things this can be that i have run across....one has he tried a different key? The key has a chip in it and if the chip goes bad then it will do this, Try a different key. Another thing to try is move the steering wheel tilt in different positions making sure the steering wheel is lock in place, then try to start it. I have seen this on mine. Third, the anti-theft mod has gone bad and you will have to take it to ford but there is something you can do about that though like I did. Since my car is hardly driven, garaged kept, and when it is its driven to the store, track, or somewhere noone will bother it. I took it to the shop that did my tune and they programmed in the tuner to shut the anti-theft module to be turned of so where it didnt effect the starting of the car. Yes, if anyone tells you different then it has been done because my car is proof. If you take it to ford and it is the module then its going to be at least over 1200 in parts and labor because it does have to be programmed or at least thats what I was told. hope that helps

It's a PATs issue. Your car will go into a theft mode. It's usually a bad chip it the key. Same thing happened to my dads car he tried his other key and worked fine.

Disconnect the negative cable from the battery for about one minute. Reconnect the cable ( make sure it's tight ), press the unlock button on your remote; start your vehicle. This worked for me. But when I was researching it I had read that if the PATS had failed then you're SOL and only a dealership can fix it. So I hope this fix works for ya.

Had some thing similar happen to me the other day!.. I simply cleared the codes with my tuner and flipped the key over, and it worked just fine!.. But I went to the Ford Dealer and got two new keys, plus the old one reprogramed for $120.00 total!...

Passive Anti-Theft. Either your key is now bad (bad chip) or PATs is acting up. You'll need Ford for one (or both if you don't have two keys). My friend rebuilt a Mustang and triggered PATs. It shuts you out of using the car pretty hardcore.

that is what happen to mine when I rebuild the engine....I dunno if it was the turner that went bad when I plugged it up to tune it that cause this issue. I would go to crank the car and it would run for a few secs backfire, then die and it wouldnt run again. It would get fuel to the plugs but the plugs wouldnt fire. Took to the shop that did the tune and they disable the anti-theft and the car ran normal. I wasnt going to pay the amout ford wanted for the repair cuz it was high....

Man! I feel like if you own the car, you should be able to get key replacements for cost. That should be something they are happy to do cause you own a Ford. If you actually bought the car there, they should do it for free!

I wish I owned the car, he's just a really good friend and I'm trying to help him out by posting it on here, but he's talking about selling it for $3k obo. I'd buy it if I had the money. I think he's taking it to ford sometime next week but I'm not sure. If it's a cheap fix, he'll probably keep it.

It may be a reciver that is under the steering wheel
that's the one that sends the signal to the chip on your key
It happens to me already

I am from Conway Arkansas and there is a fellow named Mike who lives nearby. He owns QuarterMile Mustang and that's all he works on. I don't know how far away you live, but he is a literal genius with mustangs and I am positive he could find out what the deal is.

That is such a B$*#h @$$ comment. I bet you go out and get another car every time you need a oil change don't ya?

OP So may options have been presented to you. Talk to your friend and show him the loss he will be taking if he sells it with a problem that can most likely be easily fixed.

How did you get a key with no chip? I thought the ignition system searches for it?

Same thing happened on my 1999 mustang.
I...(and a mechanic) ..first thought that it was the fuel pump...it wasn't.
I noticed that the theft light was flashing.
Under the dash was a small disconnect that had a wire come loose.
This is a design flaw...as using the tilt steering puts pressure on the very small (and short) wires coming from it.
I removed the disconnect, spliced in additional wire and hard-wired it back together...and it WORKED !
This disconnect is located under and to the right of the steering wheel if seated and facing forward.
It is a small square and has 4 very small wires coming from it.
Hopefully this will help someone.

Theft Light Flashing! Car Won't Start!

I have had problems with my '99 mustang for months. I put in a new fuel pump and I was ready to start testing the relays when I ran into this post. I moved the steering column down and up and down, and the car started in a snap. Pushed the steering wheel up, and the Theft light started flashing like crazy again and it wouldn't start. Pushed the steering wheel down again and it started. If anyone would have suggested this I would have said they were crazy. As a creature of habit, I always started the car with the tilt wheel up and put it down when ready to travel. I would have never connected the problem to the tilt wheel. Anyway, I did check the module and wires and no visual impairments or shorts that I could see. I will just have to leave the tilt wheel down. Thanks for the information.
