Restore Your Envoy’s Performance and Reliability
Is your GMC Envoy suffering from frustrating issues like a persistent check engine light, sudden stalling, poor fuel mileage, or even a complete failure to start? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your vehicle’s engine. Don’t let a faulty computer keep you stranded. This pre-programmed ECM is the definitive, hassle-free solution to get your trusted SUV back on the road and running like it should.
Common Symptoms of a Failing Envoy ECM & Your Solution
A failing ECM can cause a wide range of confusing problems. If you’re experiencing any of the following, this part is your answer:
- Persistent Check Engine Light (CEL) with communication-related Diagnostic Trouble Codes (DTCs) like U0100.
- Engine Stalling or Misfiring for no apparent reason, creating unsafe driving conditions.
- No-Start Condition where the engine cranks but won’t turn over.
- Poor Performance & Fuel Economy due to incorrect fuel and timing calculations.
- Erratic Transmission Shifting as the ECM fails to communicate properly with the Transmission Control Module (TCM).

An Expert’s Note on VIN Programming
“Many people are tempted to grab a used computer from a salvage yard, thinking it’s a cheap fix. This is a critical mistake. Your Envoy’s anti-theft system (VATS/Passlock) is tied to the VIN stored in the original ECM. A module from another vehicle will have the wrong VIN, and your truck simply will not start. It will be a ‘brick.’ Our programming service isn’t just a convenience; it’s essential for the part to function. We sync the module to your truck before it ever leaves our facility, saving you the time, cost, and headache of a tow to the dealer.”
