Restore Peak Performance to Your GM Vehicle
Is your truck, van, or SUV suffering from frustrating issues like a persistent check engine light, rough idling, stalling, or a no-start condition? These are common indicators of a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle, managing critical functions like fuel delivery, spark timing, and emissions. When it malfunctions, the entire system is compromised. This direct-fit 2009 Express 1500 Engine Computer is the definitive solution to restore your vehicle’s reliability and performance.

Frequently Asked Questions
Do I need to get this ECM programmed?
No. We handle the programming for you before shipment. Simply provide your vehicle’s VIN when you place your order, and the module will arrive ready for installation.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
What happens if I install this without programming?
An unprogrammed ECM will not work correctly. It will likely prevent the vehicle from starting due to the anti-theft system and will not have the correct data for your engine and transmission, leading to poor performance and potential damage. Our pre-programming service prevents these issues.
Is this a guaranteed fix for my check engine light?
If the check engine light and other symptoms are caused by a faulty ECM, this part will resolve the issue. However, it’s essential to ensure a proper diagnosis has been performed, as other failing components (like sensors or wiring) can also cause similar problems.
Is any additional setup required after installation?
In some cases, a security relearn or crankshaft position sensor relearn procedure may be necessary. These are simple procedures that can often be done without special tools. Instructions can be provided upon request.
