Expert Insight from the Mechanic’s Bench: In the mid-90s, GM’s vehicle security and engine management systems became much more integrated. A common mistake we see is installing a used, un-programmed module from a salvage yard. This almost always results in a no-start condition due to a security mismatch. Providing your VIN for pre-programming isn’t just a convenienceโit’s the critical step that ensures your new PCM communicates correctly with the rest of your car from the moment you turn the key. It’s the difference between a 15-minute fix and a tow to the dealership.
