Is Your Pontiac Wave Running Rough, Stalling, or Refusing to Start?
As a technician with over two decades of experience, I’ve seen countless drivers frustrated by symptoms that seem impossible to pin down. Your 2009-2010 Wave might be experiencing erratic idling, poor fuel economy, a persistent Check Engine Light, or even complete no-start situations. Often, the root cause isn’t a simple sensorโit’s the vehicle’s brain, the Engine Control Module (ECM), that’s failing. A faulty ECM can send incorrect signals to the engine and transmission, leading to a cascade of performance problems that can make your car feel unreliable and unsafe.
The Dealership Isn’t Your Only Option
Many owners think their only choice is an expensive trip to the dealership for a new ECM, followed by hefty programming fees. We offer a better, more direct solution. This is a direct-fit replacement ECM for your vehicle, and the best part is, we handle the complex programming before it ships. By providing us with your vehicle’s VIN during checkout, our specialists will flash the module with the latest, most stable GM-approved software specific to your car. This ensures all systems communicate correctly from the moment you install it.
“A customer’s 2010 Wave came in last week with these exact symptoms: it would crank but not start, and when it did run, it shifted harshly. The local shop had replaced two sensors with no luck. We scanned it and found communication loss codes pointing to the computer. After installing one of our pre-programmed ECMs, the car started on the first try and ran perfectly. It’s a common scenario where diagnosing the core component saves hundreds in wasted parts and labor.”

Plug-and-Play Installation: No Dealer Visit Required
You can perform this installation at home with basic hand tools. Follow these steps carefully for a successful replacement.
- Safety First: Disconnect the negative terminal from your car’s battery and wait at least 10 minutes for the system capacitors to discharge.
- Locate the ECM: On most compatible models, the ECM is located in the engine bay, often near the battery or firewall. It’s a metal box with large electrical connectors.
- Disconnect Connectors: Carefully unlatch and remove the wiring harness connectors from the old ECM. Inspect the pins for any corrosion or damage.
- Remove Old Module: Unbolt the mounting hardware holding the old ECM in place and remove it from the vehicle.
- Install New Module: Mount the new, pre-programmed ECM in the same location and secure it with the original hardware.
- Reconnect and Secure: Firmly plug the wiring harness connectors into the new ECM until they click into place. Reconnect the negative battery terminal. The vehicle may require a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes.
