Question about 2003 Oldsmobile Alero

1 Answer

I have a 2003 Olds. Alero 2.2 engine. This is a winter time problem only: The car will turn over but will not start using the ignition key. The car will start using the automatic starter but, until the car warms up it will not operate. If I try to put it in any gear at all it will stall. Any reviews that I have read concerning this same problem,none of them have a solution. Many people believe that the problem is with the anti theft. Thank you very much in advance

Does the security light come on an stay on when it won't start ?
The powertrain control module (PCM) will disable engine starting. Start disable may be in the form of fuel disable or starter disable, depending on engine application.
Does the vehicle have factory remote start or aftermarket ? Maybe the ignition switch is the problem . Checking B+ voltage to the switch an to circuits it powers up . Do you know what an electrical distribution diagram is ? Free wiring diagrams here

SOURCE: 1999 olds alero stall whe you take your foot off

hard start is AM is most commonly caused by a defective fuel pump pressure check valve, the other stall is issue is covered by the following procedure.
Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
