Is your family’s Pontiac Montana suddenly unreliable? Experiencing stalling, a persistent check engine light, or a complete no-start condition can be incredibly stressful.

This Engine Control Module (ECM) is the definitive answer, arriving pre-programmed to your vehicle’s specific VIN, ensuring a seamless and effective repair.
Common Symptoms & Your Direct Solution
A failing engine computer can cause a wide range of confusing issues. If you’re noticing any of the following, a faulty module is the most likely culprit:
- Check Engine Light: Especially with internal module error codes like P0601, P0602, or P0606.
- No-Start or Hard Starting: The engine cranks but refuses to start, or starts only after many attempts.
- Stalling and Poor Performance: The engine may stall unexpectedly at idle, lose power while driving, or suffer from terrible fuel economy.
- Communication Errors: Your mechanic’s scan tool cannot communicate with the ECM.
- Erratic Behavior: Unexplained transmission shifting problems or other bizarre electrical issues.
This pre-programmed 2008-2009 Pontiac Montana ECM is the direct solution to these problems, restoring the communication and control your engine needs to operate as it did from the factory.

Frequently Asked Questions
Is this ECM really ready to install when it arrives?
Yes, it comes fully programmed to the VIN you provide after purchase. This handles the main engine and transmission software. However, you will need to perform a simple security relearn procedure after installation so the module can sync with your vehicle’s anti-theft system and keys. This procedure can be done at home without any special tools and instructions are readily available online.
