I would start with you battery terminals. the side posts will get hot, melt the ring and lose connection, just grab the cables and move it back and forth. If it seems loose then try and tighten the posts. if that all seems tight and good then you might have passlock system fault. these vehicles have alot of issue with the BCM. need to codes in the computer to understand what is going on. Please note that BCM stores the odometer reading for the dash so if a used one is pruchased it will have to match the odometer. and the engine types are important. good luck.

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/

Is there a steering column security system doesn't allow starts on cold mornings?


I posted some information about your security system on the other question that you posted where you mentioned the pellet in the key on your older vehicle.

Let me ask you this: Does the starter not crank the engine when you are experiencing this difficulty? Or is the starter cranking the engine and it just won't start?

The reason I ask is because if the starter cranks and your problem only occurs on cold mornings, the problem is most likely to be caused by a malfunctioning Engine Coolant Temperature (ECT) sensor.

In any case, you should scan your computer network for possible fault codes to begin any diagnosis of either your engine control system or your security system (Unless you really like wasting your hard-earned cash trying to "GUESS" what is wrong).

Vehicle wont crank replaced starter acts like no power to starter


This may be due to the antitheft system. This is actually pretty common on GM cars. Try to start your car, when it doesn't start, look for a light on the dash that says "security" out has a picture of a car with a lock thru it. If you see this, the antitheft is the problem. Go to this link, has some trouble shooting and antitheft security fixes. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Car wont turn over replaced ignition control mordule plugs and car wont start what do u think


If it doesn't turn over at all, it could be the crankshaft or camshaft sensor, is your security light staying on? If so, it could be your security system, passlock was installed in many gm's and caused alot of problems. Have your starter checked at autozone or advance, they check them for free. If it is the security system youtube shows how to bypass the passlock system. Also, check to see if your car is getting fuel. Hope this helps.

This sounds like there is a dead spot in your starter. The easiest way to resolve this issue is to replace your starter. Many times, if you take a lot of short-distance trips over the life of your car, the wiring inside the starter itself will wear (short trips means starting it more often, causing a lot of wear over time). Then the inner wiring of the starter wears too much, it forms a "dead spot" -- when the starter is stopped at a very specific spot i will not form the magnetic force needed to torn the starter motor. This is a common issue which can be dealt with for a time if you have to save the money to replace the starter. Tapping the starter, or arcing it with a screwdriver makes the inner workings of the starter jump a little, allowing it to move out of the dead spot and kick over as normal, but it is only a temporary fix. Unless you refurbish electronics for a living, it is very unlikely that you will be able to repair the starter on your own, and such a repair takes some time, so you are better off to replace it than try to repair the starter itself.
As long as the starter does not happen to stop in the dead spot, it will work as normal ... but in time the dead spot will spread, causing the issue to worsen. You can keep forcing it to turn with the two tricks you used until you have had the opportunity to earn the money to replace the starter (or until you have a day off to get the repairs done) .. but over time this can cause more damage to other parts of the car, so I recommend replacing the starter as soon as you can.

My dad says the ignition switch maybe what's causing my 1994 Grand Prix not to start. The battery still has juice, and he says the starter is good, but maybe the starter relay isn't. What do you...


Look on the dash for a light that says "security" when it doesn't start. It's very common on GM vehicles for the security system to shut down the starter if there is a mis communication in the security system.

Car wont turn over


if the security light comes on when you turn the key to the run position (just before you reach the start position) and doesnt go off after a few seconds it is a security system issue, which is real common on that vehicle, you would have to replace the ignition lock cylinder along with the passkey wiring, but if you just leave the key in the run position for like 20 minutes the light will turn off and you can turn the key forward and start the vehicle, YOU WILL HAVE TO DO THIS EVERYTIME YOU WANT TO START THE CAR. If the security light does not stay on for more than a few seconds your probably looking at a bad starter and its under the intake manifold so its real fun to change

1999 Volvo V70 wont start


I had the same problem with the 2000 v70 XC I bought in Dec. 08. I replaced the battery, then the antenna ring (around ignition; part of the immobilizer system), and bought new keys as sometimes the chips in them do go bad. Also, if you have a key for another car with an immobilizer system on the same keyring, take it off. The multiple signals can confuse the immobilizer system. I think the antenna ring may have been one issue as, consistent with what repairpal stated, I got a crank and the engined turned over for about a second or 2 one time and then it died. The antenna ring (and the new keys) were relatively inexpensive. That worked for about a month and then I got no crank at all.  I had the starter replaced, but in hindsight I think that may have not been the problem.  I think the problem was the starter not getting juice. The starter was a very expensive solution. About 2 weeks after having the starter replaced, it wouldn't crank again.  I took it to a Volvo dealership and gave them the history. They found a corroded wire near the starter and, at least until now, that seems to have done the trick. Labor on the wire was about $100 at the dealer. Searching Volvo forums for those who have had a similar problem, I have found that others have had the "bad wire" problem.  If you are told to replace the starter by your mechanic, my advice to anyone having this problem is to have check to make sure the starter is getting juice before replacing the starter as replacing the starter (parts and labor) cost me about $650-$700.  If they find that the starter is not getting juice, they can check for wire corrision starting at the starter and working their way back.
