Is Your Truck or Van Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than a vehicle you can’t rely on. If your GM truck or van is stalling, shifting erratically, or simply won’t start, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it’s a problem that can stop your work or family life in its tracks. We offer a straightforward, reliable solution: a professionally tested, VIN-programmed engine computer that gets your vehicle running right again, without the astronomical cost and hassle of a dealership visit.
Common Symptoms & Your Solution
A faulty PCM can cause a host of confusing issues that are often misdiagnosed, leading to wasted time and money on unnecessary parts. If you’re experiencing any of the following, this module is the definitive solution you need:
- Check Engine Light: Persistent Check Engine Light, especially with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0602, or P0605.
- No-Start Condition: The engine cranks but refuses to start, often due to a lack of fuel injector or ignition coil command from the PCM.
- Poor Performance: Noticeable loss of power, reduced fuel economy, and hesitation during acceleration.
- Erratic Shifting: Harsh or unpredictable automatic transmission shifting, as the PCM plays a critical role in controlling transmission functions.
- Intermittent Stalling: The engine randomly shuts off while driving or idling, creating a dangerous situation.
This replacement module is the central command unit for your engine. By replacing your faulty original with this pre-programmed 1999 Savana 2500 PCM, you are restoring the brain of your vehicle’s operations, ensuring all components work in harmony as the factory intended.

An Expert’s Note on These GM Computers: The PCM in these late-90s GM trucks and vans is a workhorse, but after two decades of heat cycles and vibrations, internal solder joints and electronic components can fail. This often creates maddening intermittent problems that are impossible to trace. Mechanics can spend hours chasing what they think is a bad sensor or wiring issue, when the root cause is the computer itself. Installing a quality, tested, and correctly programmed 1999 Savana 2500 PCM like this one is often the fastest and most effective way to solve these complex electronic mysteries and restore original factory performance.
Frequently Asked Questions
What is a PCM and why does it fail?
The Powertrain Control Module (PCM) is the main computer that controls your vehicle’s engine and transmission systems. Over time, factors like heat, vibration, and electrical shorts can cause internal components to degrade and fail, leading to the performance issues mentioned above.
Is this computer difficult to install?
For someone with basic mechanical skills, the installation is typically straightforward. It usually involves disconnecting the battery, unplugging the electrical connectors from the old PCM, unbolting it, and then installing the new one in reverse order. Since our unit comes pre-programmed, no special computer tools are needed after installation. However, some vehicles may require a security relearn procedure, which is a simple process that can be found in your owner’s manual or online.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note during checkout or send it to us in a message. We cannot program and ship the computer without your VIN.
Will this fix my specific problem?
This PCM is a direct solution for failures of the module itself. While it resolves the common symptoms listed, we always recommend proper vehicle diagnostics to confirm the PCM is the point of failure. If you have confirmed a bad PCM with codes like P0601 or have been advised by a professional mechanic, this is the part you need.
What if I install it and it doesn’t work?
First, double-check all connections and ensure any required security relearn procedure has been completed. If you still have issues, this part is covered by our one-year replacement warranty. Contact us, and our support team will assist you with troubleshooting and processing a replacement if necessary.
