Question about 2003 Pontiac Grand Am
Hello! Unfortunately, you are experiencing a common issue with many Grand Am owners. The problem is that you have a defective PassLock sensor. When the sensor doesn't "close" when you turn the ignition, it detects a fault and will not start. If you leave the ignition in the "On" position for 10 minutes, it will reset and allow you to start the vehicle. The ignition cylinder contains the sensor, and this part is roughly $400 and not particularly easy to replace.
There are however, bypass methods available that will disable the PassLock feature entirely. I have included a link to the instructions here.
NOTE: Be aware that some of the bypass options will disable your PassLock anti theft system ENTIRELY. I recommend utilizing one of the options that explicitly states that your system will be fully operational after modification (toggle switch method, for instance)
Hope this helps and good luck! Thanks for using FixYa!
