- Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, and decreased fuel economy.

Expert Technician Tip: Many people grab a computer from a salvage yard hoping for a cheap fix, only to find their truck still won’t start. This is almost always due to the factory Vehicle Anti-Theft System (VATS) or Passlock. The PCM is electronically tied to the original vehicle’s key and ignition. Our service eliminates this roadblock. By programming the Programmed 9355699 PCM ECM to your exact VIN, we ensure the security systems match, saving you hours of troubleshooting and the cost of a tow to a specialist.
