Does the starter turn the engine over?Also let me know if this is what you tried to reset it. If any of these parts are replaced, the vehicle may start and stall for 10 (ten) minutes (LONG TAMPER MODE). If this occurs, the system MUST go through a LONG TAMPER MODE cycle. During this time, the THEFT TELLTALE will be flashing for the full ten minutes. The IPC and PCM require the full ten minutes to complete a learn cycle. The Ignition Key MUST remain in the "RUN" position until the telltale stops flashing or the cycle will have to be repeated.

Here is a guide to help you reset the system by doing a hard reboot.

I looked up the factory anti theft on your car and when it engages it doesn't disable your starter it's disables your fuel injector's from getting fuel to the engine. So the starter being inop is the problem or a different problem. So let's start by getting your starter working and see if it start's then. First thing I want you to do is have your battery tested and make sure both your battery cable's are clean and tight. After you do that we will start tracing power from your ignition switch to your starter. Here is a description on how your anti theft work's.
The PASSLOCK System is designed to prevent vehicle operation if the mechanical key is not used to start the vehicle. The mechanical key, in normal operation, will turn the PASSLOCK Lock Cylinder. The PASSLOCK Lock Cylinder will relay a Resistance Code (R-Code) to the Instrument Panel Cluster (IPC). The IPC will determine the validity of the R-Code within a preset time window started from an Ignition Switch input and will send a coded password to the Powertrain Control Module (PCM). When the PCM receives the correct code, it will allow the Fuel Injectors to operate normally.

The only true way to test a battery is to have it load tested. But we can still do some checking I would just leave the battery in question if it's good. Go to the neutral safety switch and have someone hold the key in the start position and see if you have battery voltage to the yellow wire and then check the purple wire on the neutral safety switch they should both have battery voltage with the key in the start position. Let me know what you find.

Hi thanks for taking the time to hopefully help me out,
i recently changed my starter, but before that I took the battery out for more than 24 hours, when I finally was done installing the new starter, I installed the battery, then when I went to start the car, it turned over but no start. I noticed the theft system light was 'on', not blinking, I called a few people, and they kept saying the same thing, put the key on for 10 min, then start, but nothing, then I called gm, and the said' start it, but leave it on for 40 min and then turn off and try to start it, but nothing.
What can be causing this problem? Please help me
thank you

I have the car listed above z24. The car starts and shuts off due to Pass-lock. My theft light is on, but not flashing, it is solid. I have tried ten minute and thirty minute relearn procedures, but the theft light never goes out, and Pass-lock is still active. What can I do to get my car driveable again?
