Recently while we were driving the car just died unexpectantly. then it wont start back up. I have pulled the car back to my house and have been trying to get it started again. I noticed that the starter was spinning but not engaging. So I replaced the starter, now it will turn the motor, but still not start. battery seems to be fine, have checked all connections. I am aware of the passlock problem but that isnt it this time, I have noticed that the security light doesnt stay on. Any help would be greatly appreciated. thanks

Re: 2002 olds alero wont start not security problem
You will have to see if you have spark and gas first of all. When you first turn the key to "on", you should be able to hear the fuel pump cut in for just a couple of seconds. If it doesn't, check fuses and relays. If they are okay check to see if there is power at the fuel pump. If there is, you need to change the fuel pump.
Get a timing light and hook it to any spark plug wire, and see if you have spark. If you don't, first, i would check the timing belt. If it's okay, try changing the ignition coil pack.
Let me know how you make out when you get that far.

try leaving the key on for 10-15 minutes, or however long it takes for the security light to go off. If this works it sounds like you will need to have the exciter ring on the ignition lock cylinder changed.
It its most likely the Theft Deterrent Module. If the security light turns on, then that indicates a problem. Personally I think your TDM is glitched out. It may be fine, or die tomorrow. I would seriously look into getting this fixed, or bypassing the entire system. Learn about it on this site.
Body Control Module (BCM) on both counts. Find a shop in your town that specializes in electrical systems to test it. Beware, these can be intermittent problems, so make sure they keep it until the car does what you have observed. Expect to spend about $450 for the replacment. Dealers quoted me between $700 and $1,100 for the same repair. By the way, a new BCM will probably only last you about 12 months.
With the new lock cylinder in it, turn the key on. The security light should blink. Leave the key on for 10 minutes, the security light will quit blinking and go out after 10 min. This will reprogram your security system and the car should start. Also leave a battery charger on it while the key is on, If the battery goes dead during the 10 minute reprogram sequence, you will have to start over again.
My girlfriend had the same problem, so we took it to the local dealer in Costa Mesa, CA and were told she needed a new engine to the tune of 5K. We decided to take it to our local mechanic and he discovered that the “ignition control box”, which apparently has the antitheft controls too and shuts the flow of gas to the engine because it thinks its being stolen when it malfunctions, was causing the starting problem. Once, the box was replaced it worked fine. Because the IBC controls antitheft, it will need to be “reprogrammed” be someone that has access to the proper equipment or the dealer. I think the whole thing was about $800 - $900. Sure beats $5,000
