Get Your Workhorse Running Reliably Again
Is your trusty 1997 GM truck or van giving you headaches? A vehicle that won’t start, runs rough, or shifts erratically isn’t just an annoyanceโit’s a roadblock that costs you time and money. The Powertrain Control Module (PCM) is the brain of your vehicle’s engine and transmission, and when it fails, it can cause a host of confusing problems. This replacement PCM is the definitive solution to get your vehicle back on the road, operating with the reliability you depend on.
Common Symptoms & Your Solution
If you’re experiencing any of the issues below, a failing computer is the likely culprit. This module is the correct fix for a wide range of problems, including:
- Engine cranks but refuses to start
- Poor or rough idling
- Harsh or unpredictable automatic transmission shifting
- Reduced fuel economy
- Check Engine Light (CEL) with communication error codes (e.g., U-codes)
- Stalling for no apparent reason
Instead of guessing with expensive sensors or unnecessary repairs, address the core issue. This professionally programmed 1997 Express 2500 PCM is flashed specifically to your vehicle’s VIN, ensuring it works seamlessly with your truck’s systems right out of the box, after a simple security relearn procedure.
An Expert’s Note on VIN Programming
In the world of 1990s GM vehicles, the PCM isn’t just a simple componentโit’s a security device. The VIN programming we perform is critical. It doesn’t just load the correct engine and transmission files; it ensures the PCM can communicate with your vehicle’s anti-theft system (like Passlock or VATS). Installing a non-programmed module from a junkyard will almost always result in a no-start condition. We take the guesswork out by pre-programming it with the latest GM software updates, giving you the best possible foundation for a successful repair.

Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to load the exact software and calibrations for your specific engine, transmission, and factory options. This step is crucial for ensuring the 1997 Express 2500 PCM functions correctly and communicates with your vehicle’s other modules without any issues.
Is this part difficult to install?
The physical installation is straightforward for anyone with basic mechanical skills. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. However, after installation, you will need to perform a simple security relearn procedure (often called a ‘key-cycle relearn’) to sync the new PCM with your vehicle’s anti-theft system. This procedure typically takes 10-30 minutes and does not require special tools.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM, then yes, this will resolve the issue. However, if the light is on due to a faulty sensor (like an O2 sensor or MAP sensor), you will still need to replace that sensor. This module will fix the problem if the root cause is the computer itself.
Is this compatible with my 4.3L V6 S10?
Yes, absolutely. While the title highlights the Express van, this module is compatible with a wide range of 1997 GM vehicles, including the S10/Sonoma and Blazer/Jimmy with the 4.3L V6, as well as full-size trucks, vans, and SUVs like the Tahoe, Suburban, and C/K Pickups. The VIN programming ensures it gets the correct software for your specific model.
