Is Your 1997 GM Truck or Van Running Poorly?
If you’re dealing with frustrating issues like a persistent check engine light, rough idling, stalling, or a complete no-start condition in your 1997 Chevrolet 1500 or other compatible GM vehicle, a failing Powertrain Control Module (PCM) is often the culprit. The PCM is the central brain of your vehicle, managing everything from fuel injection and ignition timing to transmission shifting. When it fails, it can cause a wide range of confusing and debilitating symptoms. This direct-fit replacement PCM, part number 8162296840, is the definitive solution to restore your vehicle’s reliability and performance.
From the Diagnostic Bay
I once had a ’97 Tahoe come in that had its owner chasing his tail for weeks. He’d replaced the plugs, wires, cap, rotor, and even the fuel pump. The truck would run fine for a few minutes, then start sputtering and die, refusing to restart for an hour. The codes were intermittent and pointed towards a crank sensor, but a new one didn’t help. After checking the wiring, we hooked up a scope to the PCM outputs and saw the injector driver circuits were dropping out randomly as the unit heated up. A new, properly programmed PCM fixed it instantly. It’s a classic case of how a failing computer can mimic a dozen other mechanical problems.
Symptoms of a Failing 1997 GM PCM
- ✔ Persistent and illuminated Check Engine Light (CEL)
- ✔ Vehicle refuses to start or stalls intermittently
- ✔ Rough or erratic engine idle
- ✔ Noticeable decrease in fuel economy
- ✔ Harsh or incorrect automatic transmission shifting
- ✔ Failure to communicate with diagnostic scan tools
- ✔ Engine misfires or hesitation during acceleration

Frequently Asked Questions
What exactly does the PCM do?
The Powertrain Control Module (PCM), also known as the Engine Control Module (ECM), is a computer that acts as the ‘brain’ of your vehicle’s engine. It controls the fuel injectors, spark plugs, and transmission, using data from various sensors to ensure the engine runs efficiently and smoothly.
Do I need to have this part programmed by a dealer?
No. The main benefit of our service is that we program the module for you before we ship it. Simply provide your vehicle’s VIN during or after checkout, and the module will arrive ready to install, saving you time and money.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a metal plate on the driver’s side of the dashboard, visible through the windshield.
Is this module difficult to install?
For most 1997 GM trucks and vans, the PCM is located in the engine bay, typically on the driver’s side fender. Installation involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. The new one bolts in its place. It’s a straightforward job for someone with basic mechanical skills. In some cases, a security or crank relearn procedure may be required after installation, which can be done with a capable scan tool.
What happens if I forget to provide my VIN?
We cannot ship the module without your VIN, as the programming is essential for it to work in your vehicle. Our customer service team will contact you to retrieve the VIN to prevent any delays with your order.
Will this fix my check engine light?
If the check engine light is on due to a fault within the original PCM, then this replacement part will solve the problem. However, if the light is on because of a bad sensor or another issue, that problem will still need to be addressed. This module will allow your vehicle to correctly report any other existing issues.
