I have the same exact problem. My car will not start for exactly ten minutes and th security light is flashing. I never know when this will happen but once it starts, the car runs like a champ. I have taken the car to the dealer and had the ignition fixed but that is not the problem. help!!
I had the ignition problem in my Impala LS '01 and I solved it, my solution was to clean the 'IGN RLY' module with a little bit of WD-40 both terminals and socket, then, i put a silica gel bag near the module (in case the humidity may form tartar again) it was an instant solution, specially in rainy weather.
I had the same problem with my Impala. It was especially annoying in the winter when I'd have to sit there and wait hoping it would eventually start. What I ended up having done was having a remote starter installed which bypassed the passlock system. So anytime that problem would happen, I could just remote start my car. So far I haven't had it happen since and it was a lot cheaper than going most other routes to fix it.

Your vehicle has whats called pass-lock II, it is an anti-theft setup. There is a procedure that you can do to reset the pass-lock system. Try these steps and see if it helps. Please let me know if it does or does not work and I will help you to further diagnose and repair the problem.
Step 1 - Attempt to start the vehicle. It will crank, but not run. The security light will be flashing on and off. Leave the key in the 'run' position for exactly 10 minutes, then the security light will stay solid or go off.
Step 2 - Turn the key to the 'off' position for 10 seconds. Attempt to start the vehicle. Some vehicles will run at this point, although many will require you repeat repeat Step 1 two more times. Make sure turn the key to the 'off' position for 10 seconds before each 10 minute cycle.
Step 3 - The vehicle is now ready to relearn the proper code. Turn the key 'off' for 10 seconds and then 'crank' the vehicle. It should be running now. The security light might stay on solid for several minutes afterwards, depending on your system.
you cant disable it, its a pass key system not a vats system (vats reads a resistance value in the key). The ignition cylinder has a sensor in it that measures a rotating resistance (then translates into a voltage reading) that the bcm reads to let the car know to start. Usually you can try and start the car, then the security light will start flashing - leave the key in the on position for ten minutes until the security light goes out. Then turn the key off, wait, then try and restart - they usually relearn the code after the first 10 minute try. Sometimes it takes three 10 minute cycles.
did you reuse the same pass lock sensor and key lock tumbler? if so the security system shouldn't have to be reset. if you replaced either lock cylinder or pass lock sensor then you have to turn the key to the start position and then to the run position and leave the key on for about ten minutes and wait for the security light to stop flashing. once the light stops flashing do the same process again. it may take up to three times to get the key code encrypted into the BCM. on the third time after the light stops flashing the car should start, if not then you may have another problem.
it could be your security system that locked itself up these cars are bad for that, the way to see is to turn the key on and see if the security light flashes on and off if so it is locked, the way to unlock it is to turn the key to the on position until all the lights come on and let it sit for 10 minutes and then turn the key off for 3 seconds and then it should start. if this doesnt help then it could be the fuel pump. hope this helps.
mine has done it for years. if it ever fails to start, only turns and turns you have to leave the key on for ten minutes, wait until the security light flashes and goes off then turnkey off and fire it up
Turn the key to "on" and let the light flash. It should stop flashing after about ten to twenty minutes. Once the light is on steady, turn it off, then start the car. I usually put another battery on jumper cables attached to the cars battery so it does not run down and die before the system re-arms.
Are you reffering to the alarm or the pass lock system that put the theft light on.....If its the alarm the put the key in the door and unlock it. If its the pass lock system put the key in the ignition and turn it on and try to start the vehicle. After it shuts itself off leave the key on for ten min until the theft light stops flashing the turn key off and try to start it again. This may take a few times....
I have the same car, I had my car fixed at the dealer. The problem is the ignition lock cylinder (where the key goes). It cost me about $340 (parts and labor). What has happened is that the cylinder is not sending the info to the starter to start the car. I guarantee you this is your problem too.
If the battery has gone dead, it could cause the security system to go into full lock-up mode. If it has locked up the accessories will work after the battery is charged back up , but the power to the starter will be cut off and it wont turn over. You need to do the 30 minute learn procedure. A GM dealer will print it out for you and you can do it yourself. It's very simple if you follow the procedure exact. hope this helps and good luck.
