Get Your Dependable Truck Running Right Again
Is your trusty GM truck or van suddenly running rough, refusing to start, or throwing a persistent check engine light?

This is the straightforward, effective fix to restore your vehicle’s performance and get you back on the road with confidence.
Common Symptoms & Your Solution
A faulty PCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, a failing engine computer is a likely culprit:
- Erratic or harsh shifting

From the Mechanic’s Bench: The Importance of VIN Programming
On these late-90s GM trucks, simply swapping a computer from another vehicle won’t work. The PCM is tied to the vehicle’s security system (often called Passlock or VATS). A mismatched VIN will trigger the anti-theft system, preventing the engine from starting. By programming your specific VIN to this programmed 09355699 PCM before we ship, we eliminate this headache. You avoid a tow to the dealer and expensive diagnostic fees. It’s the crucial difference between a part that just fits and a part that actually works.
Frequently Asked Questions
Do I need to do anything after I install this computer?

The VIN is your vehicle’s unique 17-digit identification number. You can find it on your vehicle’s registration, insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
Is this a new part?
No, this is a high-quality, tested computer that was sourced from a salvaged vehicle. This allows us to provide a reliable and affordable solution for your repair needs.
How long does the programming process take?
Once you provide us with your VIN after purchase, we typically program and ship the computer within one to two business days. Our goal is to get your vehicle back on the road as quickly as possible.
Will this fix my check engine light?
