The thing that causes the PASSLOCK to activate is the chip, if you will. If the chip is bad, ar is unrecognizable to the system, the PASSLOCK will activate. Take it to a dealer asap.
You can bypass the passlock by accessing the ignition, and cutting the yellow wire of a small 3 piece wire set that's on top of the ignition.
cut the yellow small wire from ign. switch in the column up by the switch. this is the passlock wire.

On 93 Grand Am what could cause the crank sensor and ignition module go out when you replace your starter and ignition switch-entire steering wheel?
so you replaced your entire steering wheel and switch and that did not work and was told you needed a starter. The starter was replaced and that did not work. Now it is the crank sensor and ignition module. Not sure of the symptoms, you were not spacific.... Maybe you just need to reprogram the Passlock Anti-theft system to recognize the new key. If you attempt to start the vehicle with a key that it does not recognize it will start for a second and then die, the injectors are disabled by the system. If the car turns over and does not start, I would guess that this is your problem since you changed out the ignition switch. Research the Passlock system. I am guessing you need to do a reprogram.
How do you fix a flooded engine on a Pontiac Grand Am?
Let it set it should start. If not your vehicle is equiped with an anti-theft system, it may be malfunctioning. The Passlock Anti-Theft on all GM vehicles will disable the fuel injectors if it thinks the vehicle is being stolen. This could hapen if you changed keys or the sensor in the ignition cylinder is bad. This would give you the same effect as if the vehicle was flooded. It might start for a few seconds, then die. Try the reset method below. Reset Method or the Passlock 2 system, put the key in the ignition and turn the engine over (the car should not start, if it did you are done), turn the key to the ON position, let it set for 10 fmin. The security light should be flashing. After 10 min. the security light should stop flashing the car is ready to learn the new key value. Turn the key off, wait 5 seconds, and then try to start the car.
What would cause a 40amp ignition batt fuse to blow on a 97 Malibu?
There is a sort somewhere in the starting system
Would a car door key without a chip damage the ignition system?
Yes! If you take an uncoded key (like an emergency door key) and try to start the car, the ignition system will disable itself. This is why locksmiths generally will not cut a spare key for you, and if they are willing to cut one, some will make you sign a waiver that says you will not place the key in the ignition to avoid getting sued later. A dealer can unlock the system for you. <><><><><> There is also a procedure for coding a new key to your ignition system. Again, see the dealer.
Can a bad ignition coil cause a car not to start?
yes once the ignition control module heats up it would cause the vehicle to stall. usually after it cools down the vehicle will restart again.
Where is ignition module on 2002 impala?
The ignition module on a 2002 Impala is located in part of the electrical system. In some cars, the module kept the car from starting. When the key was turned there would not be a clicking noise. The module works with the passlock system of the car.

Can using same car key for years make security light and service engine light come on in 02 impala after putting new battery in?
Your vehicle has the PassLock system, not the older PassKey. In the PassKey system there was a resistor pellet in the key that would go bad. In PassLock, the guts of the system are behind the lock cylinder. PassLock has almost a 100% failure rate and the way to fix it is to replace the lock cylinder assembly. I've attached a post link that describes what you need.
2004 Chevy Malibu sometimes will not start Anti theft light is also on Only way to start is to reset Any suggestions?
The anti-theft feature prevents the car from being started when one of several anti-theft devices is faulty are have otherwise been activated. The problem you describe might be the ignition switch, which is known to wear out quickly on those models. The system can be completely disabled only when the car is running (meaning the theft deterrent system is inactive after the Passlock II system detects the proper key in the ignition). A wire can be cut that would permanantly disable Passlock II, meaning any key that opens the door (or a screwdriver) could start the car. If the ignition swtich goes out or this wire is cut while the engine is off (theft deterrent system is active) then the car will have to be towed back to the dealer to have the ignition system replaced and reprogrammed.

How do you reset passlock for 2001 Chevrolet Impala?
There are a myriad of possible "solutions" available. If you are even just a little bit technically savvy you can with a little bit of effort disable and or bypass the "passlock" system. Just Google Chevy impala passlock disablement or Chevy impala passlock bypass. There are several ways to do this and it would be better for you to read all the information available and arrive at your own decision. This seems to be a "VERY PREVELENT PROBLEM"
Why would myChevy cavalier has no spark and or fire the theft system light is on have changed everything?
That's their "passlock' system, it cuts off fuel to the engine. I think it's activated by the car being turned on w/o a key in the ignition. I'm not too sure that replacing everythng will solve your problem. ask the dealership I guess, unless someone else knows? That's their "passlock' system, it cuts off fuel to the engine.

Is there a fuel system shutoff and reset on a 2001 Grand Am?
I have a 2001 and it does have a fuel shut off, but only activates when the passlock system is activated. If it seems to happen intermittently, have a new key made. My old keys and lock cylinder were worn out and causing the anti-theft system to engage. If you go through the 10-minute reset procedure (in your manual) it will start. I had a new key made (not cut from an existing key) and the problem has not happened again in over 6 months. Eventually I am told you would need a new ignition cylinder, but this is a cheaper temporary solution.In short, the only fuel shut-off is the pass-lock fuel pump disabler.Hope that helps.AnswerI have a 2000 Pontiac Grandam with the famous Ass-Lock system installed, had the same problem, very frustrating.Your anti-theft passlock system senses the RESISTANCE value across your ignition cylinder when your key is in it, over time your key will 'wear' the inside of your ignition cylinder and itself thus changing the 'R' ( resistance value ) to the trigger threshold and causing intermittent ' fuel shutoff ' problems due to Passlock. A new Key and ignition coil will fix the problem, OR there is an easy workaround.From inside the car, pull the center panel-shroud off, this is the plastic housing surrounding the stereo and climate controls, it is just clipped on and easily removed, once off you will be able to see and access the wire bundle coming off the rear of your ignition cylinder,you may need to remove some of the black insulating wrap to reveal the wires. You are looking for the only yellow wire, this is the ' R ' ( resistance sensing ) lead for your passlock, with the ignition turned on, cut this wire, the Passlock will assume sensor failure, illuminate the SECURITY light in your dash and bypass the fuel-shut-off portion of the protection system. If you wish you can remote a switch by addig about 5 bux worth of extra wire and a switch between the now cut ends of the yellow 'R' lead and routing the remote switch under the dash, this allows you to re-enable your passlock fuel bypass security system at your leisure.The only disadvantage to this workaround is the constant illumination of the SECURITY light, however your central locking and all other features remain fully functional and hey you won't have to spend another 10 minutes beating your dash waiting on the system to reset. Good Luck !
Where is the distributor cap on a Kia Sephia?
If it's a newer vehicle within last 10 yrs then most likely DIS system (distributorless ignition system) and there isn't one, only coils. if it does have one it would be on the right side of the cylinder head you cant miss it
