Restore Your Vehicle’s Performance with a VIN-Programmed Engine Control Module
If you’re dealing with a frustrating Check Engine Light, unpredictable stalling, or a car that simply won’t start, the problem often points directly to a failing Engine Control Module (ECM). As the brain of your vehicle’s engine, a faulty ECM can cause a cascade of issues that are difficult to diagnose. This isn’t just an inconvenience; it’s a reliability problem. This is the definitive solution for your 2006 Pursuit Engine Module and a wide range of other GM vehicles, delivering renewed performance and peace of mind.
We take the guesswork and extra expense out of the repair. Unlike a generic module from a parts store or salvage yard, this unit comes professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN). We install the latest GM-certified software updates, ensuring optimal fuel delivery, ignition timing, and emissions control. This means no expensive trip to the dealership for programming—it arrives at your door ready for installation.
Case Study: A Tricky Diagnosis
I remember a 2006 Cobalt with the 2.4L engine—a very similar platform to the Pursuit—that came into my shop with an intermittent no-start condition. The owner had already replaced the battery and starter. We scanned it and found a U0100 ‘Lost Communication with ECM’ code, but it was sporadic. After checking all the wiring, grounds, and power feeds to the ECM, everything seemed fine. On a hunch, I gently tapped the ECM housing while monitoring the scan tool data, and the connection dropped instantly. The culprit was an internal failure in the module’s main processor, a common issue I’ve seen over the years due to heat cycles and vibration. Replacing it with a VIN-programmed module like this one solved the problem permanently.
Is Your Vehicle Showing These Signs of ECM Failure?
A failing engine computer can manifest in many ways. If you’re experiencing any of the following, it’s a strong indicator that your ECM needs attention. Look out for:
- ✔ Check Engine Light is illuminated with communication codes (like U0100) or internal processor fault codes (P0601, P0602, P0606).
- ✔ Engine cranks but refuses to start.
- ✔ Unexplained stalling or rough idling.
- ✔ Noticeable decrease in fuel economy.
- ✔ Misfires or hesitation during acceleration.
- ✔ Transmission shifting issues or failure to engage gears properly.
- ✔ Apparent loss of spark or fuel injector pulse.
A Straightforward Guide to Installation
Installing your new 2006 Pursuit Engine Module is a job most DIYers can handle in their own garage. Following these steps will ensure a smooth process.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the Old ECM: On the 2006 Pontiac Pursuit, the ECM is typically located in the left front of the engine compartment. Consult a repair manual if you are unsure of the location for your specific vehicle.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed module into place. Securely reconnect the electrical harnesses, ensuring they click and lock into position.
- Reconnect Power: Reattach the negative battery terminal and tighten it securely.
- Perform Security Relearn: Your vehicle will likely require a simple security relearn procedure to recognize the new ECM. This usually involves turning the key to the ‘ON’ position for 10-15 minutes, then off, and repeating two more times before starting the engine.

What exactly does ‘VIN Programmed’ mean?
What exactly does ‘VIN Programmed’ mean?
It means we load the module with the specific software and calibrations for your exact vehicle using your 17-digit VIN. This ensures all systems, from the engine to the transmission and anti-theft, function correctly right after installation, just like a new part from the dealer.
Will I need any special tools to install this?
No special tools are required. Basic hand tools, such as a socket set and ratchet, are all that’s typically needed to unbolt the old module and install the new one. The most important part is the security relearn procedure, which only requires the use of your ignition key.
How do I provide my VIN after purchase?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s VIN. You can typically reply to your order confirmation email or use a contact form on our website. We cannot ship the module until we receive the VIN to program it.
Is this a reliable fix for a 2006 Pursuit Engine Module?
Absolutely. This module is tested to meet or exceed original equipment specifications. By addressing the root cause of common electronic failures and loading it with the latest software, it provides a dependable, long-term solution to your vehicle’s engine management problems.
