Is Your Pontiac Pursuit Running Rough?
If your 2006 Pontiac Pursuit is experiencing perplexing issues like stalling, poor fuel economy, a check engine light that won’t go away, or even a no-start condition, the culprit is often a failing Engine Control Module (ECM). The ECM is the brain of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it starts to fail, it can create a cascade of problems that are frustrating and difficult to diagnose.
We had a 2006 Pursuit come into the shop that had its owner completely stumped. The car would run fine for about 15 minutes, then suddenly start misfiring and lose power, eventually stalling. The owner had already replaced the spark plugs, ignition coils, and even the fuel pump with no success. After hooking up our advanced diagnostic scanner, we noticed erratic data readings from multiple sensors that didn’t make sense together. This pointed us directly to the central processing unit – the ECM. The internal circuits were failing under heat. We installed a VIN-programmed replacement module, and the car ran perfectly, solving a month-long headache for the customer in under an hour.
Symptoms of a Failing Engine Control Module
- ✔ Check Engine Light is illuminated with various, often inconsistent, trouble codes.
- ✔ Engine performance issues such as stalling, misfiring, or rough idling.
- ✔ Noticeable decrease in fuel efficiency.
- ✔ The vehicle fails to start, even with a good battery and starter.
- ✔ Transmission shifting problems, including harsh shifts or getting stuck in gear.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Intermittent issues that seem to have no logical cause.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the ECM with the exact software and calibrations specified by GM for your vehicle’s engine, transmission, and options. This ensures a perfect match and proper function without any additional programming required.
Is this part difficult to install?
Installation is straightforward for a DIY mechanic with basic tools. The ECM is typically located in the engine compartment. The most important step is to disconnect the vehicle’s battery before starting the replacement. After swapping the modules, reconnect the battery, and the car is ready to go.
Will I need to perform a security relearn procedure?
In most cases, our programming handles the security information, making the unit plug-and-play. However, on some GM vehicles, a simple 10-30 minute key relearn procedure may be necessary. This can be done without any special tools, and we can provide instructions if needed.
What if my original part number is different?
That’s perfectly fine. GM often updates part numbers over the years. As long as your original part number is listed in our interchange list (12590032, 12602044, 12603530, etc.), this module will be the correct, updated replacement for your vehicle.
Is there a warranty on this module?
Yes, all our programmed modules come with a comprehensive warranty. Please refer to the warranty tab on this product page for specific details and duration. We stand behind the quality of our parts and programming service.
