An Expert’s Note on VIN Programming
“I’ve seen it countless times in the shop: someone buys a used computer online, plugs it in, and the vehicle still won’t start. That’s because on these late ’90s GM vehicles, the PCM is tied to the specific VIN for security and operational parameters. Without proper programming, the vehicle’s anti-theft system (Passlock/VATS) will prevent it from starting, and the transmission won’t shift correctly. Our pre-programming service eliminates that entire headache. We ensure the GM 09355699 Engine Computer you receive is a perfect digital handshake for your exact vehicle.”

How can I be sure this will fix my vehicle?
While this part is the correct solution for the symptoms listed, we always recommend that a proper diagnosis is performed by a qualified mechanic. This ensures you are replacing the correct part and avoids unnecessary expenses.
