I ran into this once also, and I remember that I just disconnected the battery for about half an hour.

Try that if you haven't already.

I have a 99 cadillac deville it turns over, cranks up but won't stay cranked i replaced the starter and the plugs it still wont stay cranked


Antitheft or Security system failure is a common problem on GM vehicles. Every time you put your key in the ignition, the vehicle's security system reads the signal from your key to make sure it is OK to run. When it receives the "correct key" signal, the security system allows the starter to turn over, and/or the fuel injectors to function and your car works like it normally does every day. If you were to use a different key, or try to hot wire it, the system would shut down these parts of your car, thus making the vehicle completely immobile. This is GM's way of preventing vehicle theft. The problem is that the system is known to fail quite commonly. It has been failing consistently for around 30 years. When it fails, two things can happen. First, you turn the key and nothing happens at all. Lights work, radio works, windows work... just not the starter that you need to start the vehicle. This is a "starter immobilizer". Second, you turn the key and the vehicles starts just fine, but then stalls in 2-5 seconds. This is a "fuel immobilizer". It literally cuts off the fuel injectors and stalls the vehicle to immobilize it. These are normally, but not always followed by a light on the dash that says SECURITY or ANTITHEFT. These lights are to inform you of the system's failure to collect the information it needs from your key to the computer. If your security/antitheft light is on, odds are you will be stranded soon, if not already. Remember that the security system controls the security light. If the system is failing, the light may never warn you of the failure. There is a lot of info on this site that you can read up on. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Security maybe ?


Do you have a spare Key ? The key is probably the most likely cause of your problem. Shorting the two main terminals of the starter motor will only make the starter spin, to engage the starter with th fly-wheel you need to short the main lead (usually the outer one) with the solenoid terminal (smaller terminal) However this will not energise th fuel solenoid etc that the security system also disables. You should have your key cloned at your local lock smith retailer before it fails all together. I am an auto-electrician and seen this many a time. good luck.

Battery ok car wont start


You really need to be a bit more specific. Does the engine crank when you turn the key? If the engine does crank, does it sound like it is trying to start but won\'t? What kind of car is it? I don\'t think anyone is going to be able to help you with this particular problem without a bit more info...
All anyone can tell you at this point is, You battery seems to be okay...

2003 ford expedition will not crank below 50 degrees. Security light on the dash will flash real fast. motor will turn over just will not crank. later in the day when it warms up it will start right up and...


It can be as simply as a bad battery. The Antitheft system views a low battery as an attempted theft action. Then the Antitheft cuts cranking voltage to around 7 Volts to prevent the engine from starting.

Battery voltage drops in cold weather. This would explain your problem and the activation of the Antitheft light.

Please rate my info. You might try adding a battery charger for a few minutes before you try starting it and see what effects it has.

Another idea is to turn off the A/C when cranking. The A/C clutch is a big drag on the system AND is temperature controlled to disengage the clutch at lower outside temperatures. If this control is not working, the A/C would not disengage.

You can get the starter tested on the vehicle with a DRAW test. The battery can be tested too. FREE at most big parts stores like Autozone.

Hi all,I have a Ford focus 2004 tdci 1.8 and the immobiliser intermittently won't turn off,I've tried both keys and its still won't start.kind regards Dean


Ford products are sensitive to changes in Battery voltage. The system views low Voltage as an attempted theft and makes the Alarm go off.

Remove the Battery, return it with a full charge or new Battery. Some other symptoms would be slow cranking or clicking like a dead battery. The Antitheft reduces starter Voltage to around 7 Volts making starting nearly impossible.

Please rate my info. If all else fails, the Identity in the car memory may no longer match the identity on the car keys. You would need to have a Dealer rematch the keys to the car.

The key wont turn


With this year model it is most likely the key and lock barrel are both worn so they don't match anymore. Take the key to an auto locksmith and explain. He can cut another key with a little extra metal on the profile to get started, but most likely you will then need a new barrel and key fitted.

2000 Chevy Impala just had a used engine installed. Battery is brand new, but the car will not even turn over when you try and start the car. THe radio lights and all the electrical components work fine....


These cars and many many many other gm cars and trucks are equipped which an antitheft feature. Many times on engines swaps and ignition changes, this system gets interrupted because the computer is not seeing the proper signal from the original equipment. Try to start the car, when it doesn't turn over, leave the key in the "on" position. Look for a light near your gauges that says "security" or "antitheft". If you see this indicator light, then the problem is definitely the antitheft system. Fixing it is rather expensive. Bypassing it is relatively cheap. This link explains everything you need to know.

I Have a 2006 pontiac G6 gt with the 3500 engine, The battery was removed positive side first and now after it was replaced the fuel pump isn't working, everything else seems fine but the pump...


You can't fix it yourself. It takes a scanner at your Local Dealership to do it. People do it, (new battery) everyday unaware that doing so can and usually does, arm the theft system and either kills the radio or the whole car. To me it's just another built-in defect that requires dealer assistance. It's a buzzkill I know, and it probably won't be long until car owners won't even have access to the engine compartment. Sorry.
