Is Your Pontiac Pursuit Running Rough or Not Starting?
If your 2006 Pontiac Pursuit is suffering from a persistent check engine light, erratic engine behavior, poor fuel economy, or even a no-start condition, the root cause is often a failing Engine Control Module (ECM). As the central computer for your engine, the ECM is responsible for managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it begins to fail, it can cause a cascade of frustrating and difficult-to-diagnose problems. Don’t let a faulty computer keep you off the road. This direct-fit replacement ECM is the reliable, cost-effective solution you need.
From the Diagnostic Bay
We had a 2006 Cobalt (which shares a platform with the Pursuit) come into the shop with a phantom misfire on cylinder 3. The owner had already replaced the spark plug, ignition coil, and fuel injector, but the P0303 code kept returning. After hours of chasing wires, we hooked up our scope to the injector control wire at the ECM. We found the driver circuit inside the original module was failing intermittently under load, causing the misfire. We installed one of our pre-programmed modules, performed the security relearn, and the car ran perfectly. It’s a classic case where the component, not the wiring or sensors, is the hidden culprit.
Symptoms of a Failing 2006 Pursuit Engine Module
- ✔ Persistent Check Engine Light (CEL) illumination
- ✔ Engine stalling, stuttering, or misfiring
- ✔ Noticeable decrease in fuel efficiency
- ✔ Difficulty starting the engine or a complete no-start condition
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Failure to pass state emissions testing
- ✔ Communication errors with diagnostic scan tools

Frequently Asked Questions
Do I need to have this module programmed?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during or after checkout, and the module will arrive ready to be installed.
Where is the ECM located on my 2006 Pontiac Pursuit?
On the 2006 Pursuit, the Engine Control Module is typically located in the left-hand (driver’s side) front of the engine compartment. Always disconnect the battery before attempting removal or installation.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the ECM, then yes, this part will resolve the issue. However, it’s crucial to ensure that the diagnostic trouble codes (DTCs) are not being caused by other faulty sensors or components on the vehicle. This module corrects issues originating from the computer itself.
What is a security relearn procedure?
After installing the new ECM, your vehicle’s anti-theft system may need to relearn the new module. For many GM vehicles of this era, the process is simple: turn the key to the ‘ON’ position for 10-15 minutes, then turn it off, and then start the vehicle. Instructions for your specific vehicle can be easily found online or in a service manual.
What if my original module has a different part number?
As long as your original part number is one of the interchangeable service numbers listed above (e.g., 12602044, 12603530, etc.), this module is the correct replacement for your vehicle. We program it based on your VIN, not the old part number, to ensure it has the correct software.
