Is Your Buick Allure Running Rough?
If you’re dealing with a persistent check engine light, poor fuel economy, engine stalling, or a no-start condition, a failing Engine Control Module (ECM) is often the culprit. As a mechanic with over two decades of experience under the hood, I’ve seen how a faulty ECM can turn a reliable car into a constant headache. This isn’t just a part; it’s the brain of your engine, and when it’s not working right, nothing else will. Don’t let frustrating electrical gremlins keep you off the road.

Expert Pro Tip from 20+ Years in the Shop
Before you condemn your old ECM, take 5 minutes to check the main engine-to-chassis ground strap. I’ve seen dozens of vehicles, especially GM models from this era, come into my shop with classic ECM failure symptoms. More than a few times, the real issue was simply a corroded or loose ground strap causing voltage drops and confusing the computer. A quick cleaning with a wire brush at the connection points can sometimes resolve the issue. If the problem persists, then you can be confident the ECM is the next logical step.
Easy Installation for Your 2010 Allure ECM
You don’t need to be a master technician to complete this job. With basic hand tools, you can get your car running smoothly again in under an hour. The ECM on the 2010 Allure is typically located in the engine compartment on the driver’s side.
- Safety First: Disconnect the negative terminal from your car’s battery and wait 10 minutes for the system to fully discharge.
- Locate the ECM: Find the module in the LH (driver’s side) engine compartment.
- Disconnect the Connectors: Carefully unclip the wiring harness connectors from the old module. Inspect the pins for any corrosion or damage.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket.
- Install the New Module: Bolt your new, pre-programmed ECM into place and securely reconnect the wiring harnesses.
- Reconnect the Battery: Re-attach the negative battery terminal. Your vehicle may require a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes.
