Restore Peak Performance to Your Vehicle
Is your 2006 Pontiac Pursuit or other compatible GM vehicle suffering from frustrating engine issues? A faulty Engine Control Module (ECM) is often the culprit behind problems like a persistent check engine light, poor fuel economy, unexpected stalling, or erratic shifting. The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to emissions control and transmission function. When it fails, the entire system’s performance is compromised. This replacement Engine Control Module, part number 12602044, is the definitive solution to restore your vehicle’s reliability and drivability.
From the Diagnostic Bay
We recently had a 2008 Chevy Malibu come into the shop with a mysterious no-start condition. The owner had already replaced the battery, starter, and fuel pump with no success. After connecting our diagnostic scanner, we found multiple communication error codes pointing to a network failure. Instead of a complex wiring issue, the root cause was a shorted ECM that was bringing down the entire vehicle communication bus. Once we installed a VIN-programmed ECM just like this one, the car fired right up and all systems returned to normal. It’s a powerful reminder that the ECM is the true brain of the operation.
Symptoms of a Failing Engine Control Module
- ✔ Persistent Check Engine Light (CEL) illumination
- ✔ Engine stalling, stumbling, or misfiring unexpectedly
- ✔ Noticeable decrease in fuel efficiency
- ✔ Difficulty starting the engine or a complete no-start condition
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Loss of power and poor acceleration
- ✔ Failure to pass emissions testing

When you purchase this module, we will flash it with the latest official GM software updates tailored specifically to your vehicle’s VIN. This ensures that your new 2006 Pursuit Engine Module communicates flawlessly with the engine, transmission, anti-lock brakes, and security systems, just as the original did from the factory.

Frequently Asked Questions
Do I need to have this ECM programmed?
No. We handle the programming for you before shipment. Simply provide us with your vehicle’s 17-digit VIN during or after checkout, and we will flash the module with the correct software for your specific car.
Is any other procedure required after installation?
In many cases, you may need to perform a simple security relearn procedure, also known as a key relearn. This can typically be done without any special tools and involves a sequence of key turns. Instructions are readily available online for your specific model, or you can consult a mechanic.
Where is the VIN located on my vehicle?
Your VIN can be found on a metal plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
How can I be sure the ECM is my problem?
While the symptoms listed are common for a failing ECM, it’s always best to have a proper diagnosis performed by a qualified mechanic. This ensures you are replacing the correct part and not overlooking other potential issues like faulty sensors or wiring.
Is this a new or used part?
This is a high-quality, tested, and guaranteed functional used OEM part. Each unit is inspected and then programmed with fresh, vehicle-specific software to ensure it performs to original factory standards.
