Is Your GM Truck or Van Running Rough? Get It Back in Order.
There’s nothing more frustrating than a vehicle you can’t depend on. If your 1997 Chevy, GMC, or Isuzu is suffering from stalling, a rough idle, poor fuel economy, or a persistent check engine light, the problem often traces back to a failing Powertrain Control Module. This isn’t just an inconvenience; it’s a critical failure that affects performance, reliability, and your ability to get the job done. This module is the central command for your engine, and when it falters, the entire vehicle suffers. You need a solution that works, and this is it.
Common Symptoms & Your Solution
A failing PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, this VIN-programmed module is your definitive solution:

Expert Insight: The ‘Spider’ Injection Connection
Many 1997 GM trucks with the 4.3L, 5.0L, and 5.7L engines use a Central Port Injection (CPI) system, often called the ‘spider’ injector. A failing PCM can send erratic signals to this system, causing symptoms that look exactly like a bad injector assembly or fuel pressure regulator. Mechanics and DIYers can spend hundreds of dollars chasing fuel system issues when the root cause is actually the computer. By starting with a correctly programmed 1997 Express 2500 PCM 16229684, you ensure the engine’s brain is giving the correct commands, potentially saving you from a costly and unnecessary fuel system repair.
Don’t let a faulty computer keep your reliable truck off the road. This is the correct, professionally prepared part to restore your vehicle’s core function and give you confidence behind the wheel again. After placing your order, simply provide us with your VIN, and we’ll handle the programming before shipping your new 1997 Express 2500 PCM 16229684 directly to you.
Frequently Asked Questions
Do I need to do any programming or flashing myself?
No. This PCM arrives at your door fully programmed to your vehicle’s specific VIN with the latest software from GM. It is designed to be a direct-fit component, simplifying the installation process.
Where is the PCM located on my 1997 GM truck or van?
On most models covered by this part, including the Express van, pickups, and SUVs, the Electronic Control Module is located in the engine compartment on the driver’s side (LH side), often near the battery or fender well.
What is the difference between a PCM, ECU, and ECM?
The terms are often used interchangeably. ECM (Engine Control Module) typically only controls engine functions. TCU controls the transmission. A PCM (Powertrain Control Module), like this unit, is an integrated computer that manages both the engine and the transmission, which is standard for these 1997 GM vehicles.
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 part is the correct solution. However, the light indicates a trouble code has been stored. It is always best to have the codes read to ensure the problem isn’t with a different sensor or component on the vehicle.
How do I provide my vehicle’s VIN?
After you complete your purchase, you can send us a message with your 17-digit Vehicle Identification Number (VIN). We must have this number to program the module correctly before we can ship it.
