The computer won't let me in without a systm passwod it just started doing this

Cougar driving, then just stopped stalls rolling and will not restart? Tried everything? As seen all over the web, usually starts to missfire some first then suddenly dies never to start again? Changed every sensor with no luck? Even one person changed the entire engin and still didn't start.

Here's the deal, When cranking the engine notice that the RPM gage doesnt move, also if you checked, you are not getting spark or fuel, you probably had one ignition trouble code saying bank one or similar.

Long story short, it's the computer, PCM, engine management systm or whatever you want to call it. Yep thats it, that is the problem, a bad computer.

Open the hood, dissconect battery, now upper left, lift up the power steering resavoir, move it to the side. See the computer plug with the bolt in the center. Loosen the bolt all the way, go in the car under the passenger dash, remove screw holding the plastic tab under the computer, pull it down and out.
Now, get the info off of it, call a place online, I used AES, buy a remanufactered one, cost me about $300, once it arrives reinstall in reverse manner, connect the battery last. Now the cars security system will need programmed to the new computer so it will not crank yet, tow it to a local Ford dealer for about $60 , bring them all your keys and remotes, they will program the computer and security in about an hour for $115. Now your back in buisiness.
So plan to spend $475 bucks but that will do it.

sound like problem in the theft security systm,try this insert another key in the ignition switch, the other key could be worn where pcm and bcm dont recognize it. and switch ignition on engine off watch padlock symbol with ignition switch left on 10 minutes the padlock symbol will extinguish or turn off then you will turn off ignition switch wait 5 seconds then try starting vechicle if start your theft security failing need let dealership check it out.

Use f10 setup, restore to default. which removes all passwords in the bios.

The only way to do it is to re connect to a computer and reboot from backup or start fresh.

It is possible that the motor capacitor is weak and so does not start by itself. So use a similar value capacitor in parallel to confirm.check this link;

Hello
The default password for this device is [ 0000 ]. Just enter this when it asks for password. Sometimes, it won't accept this at first time to cheat you. Just enter this once again. The set passoword will be cleared, and you have the chance to set an other password, and have to. OK.

I think if you do not have a recovery disc then the operating system needs to be reinstalled. It is also possible that the system needs a virus scan if there was a case of malwares within the PC.

go to safe mood and then go to administrator account and you can go on and change the password

When you use up all your tries it clears everything for security reasons. Do you have a sim card? If you take it out and type in the passwod for the last time, it wont do any damage. If you dont, Im afraid you are effed...
