- No-Start Condition: The engine cranks but refuses to start due to a lack of fuel or spark command from the PCM.

Frequently Asked Questions
Do I need to do any programming myself?
Absolutely not. The main benefit of our service is that we handle all the programming for you. Simply provide us with your vehicle’s VIN after purchase, and we will flash the module with the correct factory software. It will arrive ready to install.
Where do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit VIN. We cannot ship your part until we receive this information, as it’s essential for the programming process.
Is this a new or used part?
This is a high-quality, inspected component that has been professionally tested and programmed by our expert technicians to ensure it meets strict performance and reliability standards for your vehicle.
What if my original part number doesn’t match 9357440 exactly?
No problem. This module is a direct replacement for a range of GM service numbers, including 09356741, 16236757, 9356741, and others listed in the description. As long as your vehicle is on the compatibility list, we will program the correct software for it.
Will this fix my car’s ‘No Start’ problem?
A faulty PCM is a very common cause of no-start conditions where the engine still cranks. While this part is often the solution, we always recommend proper vehicle diagnosis to confirm the PCM is the point of failure before ordering. This part is designed to fix a confirmed bad 1999 Oldsmobile Alero PCM.
How difficult is the installation?
For most compatible vehicles, the PCM is located in the dash or engine bay and is accessible with basic hand tools. The process typically involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in reverse order. It’s a manageable job for a confident DIYer.
