Intermittent faults like that are very difficult to diagnose, and near impossible over the internet. Best or first thing you should do is have the engine computer scanned for trouble codes-Autozone does that service for free, using an OBD-2 scanner device. OBD stands for on board diagnostics.
If you get any trouble codes, it may point to the problem. You can post them here for help, or have a mechanic or technician check it out. Good luck (from another senior).

SOURCE: 1999 Alero stalling and trac off light coming on

does the rpm motor kick down? you may need to check your vacuum hoses, and also you may want to check your exaust, sounds wierd but that can cause the car to stall at times.as for the traction light, your hitting the brakes to hard. try slowing down a little slower while stopping, and keep distance for saftey.. if you can take it a little slower at lights and turns, without braking hard and it stops stalling.

Change your idle control sensor, but first make sure your throttle linkage isn't sticking.

There have been alot of this type problem you describe. That body style of GM car has had meny ignition issues with the PASSLOCK 2 system. The system for some reason thought it was being stolen, and shut down. The security light might not blink or come on at all in some cases. It should but may not. (if there are issues with the BCM (Body Control Module) or ECM (engine Control Module) The Chime you heard may have been a security reset indicator notice. Thlling you that the Security System incountered a problem,and was ready again.

SOURCE: Hard starting when cold ( engine cranks normally )

see if your engine has a ECT sensor (temp sensor that delivers information to your ECM) they are installed on the intake side of the cylinder head, it usually has 2 cables, have it checked replace if necesary

pull one sparkplug and crank the engine to see if you are getting spark. then check to see if there is fuel getting to the injectors, without fuel and spark at the right time an engine won't run

1990 Oldsmobile toronado will not crank


If your check engine light is on get it scanned. If not pull the camshaft sensor and make sure the magnet is still in place on the cam shaft. You might need to crank it once or twice to turn the camshaft.

I have a 2000 oldsmobile alero and i drove it for like an hour and then when the temp. got to half it died and i let it sit over night and it will not start and the check engine light didnt come on until...


here are some causes for a bad coolant sensor-- rich running engine, increased vehicle emissions, engine shutdowm. if the sensor is bad, then when at normal tempurature the sensor is sending incorrect info to pcm. this sensor controls fuel and various functions. it is used to send correct info to pcm. so to compensate for engine management. have a good day !! have it scanned to find problem code. if check engine light is on.

Oldsmoble Alero ignition security problem


It doesn't have to be the security. a dead battery won't let the car crank either. With a security problem the car will crank but not start. The security can be reset if the battery is charged and up. Turn the key on ( do'nt crank ) the security light will stay on if it needs to be reset. If it remains on leave the key on for 15 minutes around then it will go out. turn the key off and then turn it right back on, the security light will be on again. Leave the key on till the light goes out again, then turn it off then turn it back on , wait again when it goes out turnthe key off then right back on then crank the engine and it should start. With a scanner the code will be security neweds to be reset. Thia is all anyone can do to reset the security and it's what you were charged $450 for. Following directions.

Alero will crank awhile before it finally starts w/ more details


May have small fuel leak or fuel pump sending unit leak down. Or fuel pump psi low.

After 30 minutes try this turn key on. do not try to start wait 10 seconds turn key off then on again 10 seconds then try & start if it starts right away fuel system is losing PSI either back through the fuel pump or a leak in line. If you can find no leaks would suggest replace fuel pump & assembly.
Another possible but rare fuel injectors may be leaking fuel over time & dropping PSI needed for start up.
