Is Your Truck or Van Running Rough? Get It Back on the Road.
There’s nothing more frustrating than a dependable workhorse that suddenly won’t start, stalls unexpectedly, or runs with a persistent check engine light. For many 1996 GM trucks and vans, these issues point directly to a failing Engine Control Module (ECM). This isn’t just an inconvenience; it’s downtime that costs you time and money. This module is the direct, reliable solution to get your vehicle’s brain working correctly again, programmed specifically for your vehicle to ensure a smooth, hassle-free installation.
Common Symptoms & Your Solution
A failing ECM can cause a wide range of confusing problems. If you’re experiencing any of the following, a properly programmed replacement is the definitive fix:
- Complete No-Start Condition: The engine cranks but will not fire up.
- Stalling & Rough Idle: Your vehicle stalls at intersections or idles erratically.
- Poor Fuel Economy: A sudden, unexplained drop in MPG.
- Check Engine Light: Persistent codes related to module communication (U-codes), injector circuits (P0201-P0208), or processor faults.

A Veteran Technician’s Insight
I’ve seen countless 90s GM trucks come into the shop with bizarre, hard-to-diagnose electrical gremlins. The owner has often replaced sensors and wires, chasing a problem that lives inside the ECM itself. The key to a successful repair isn’t just swapping the box—it’s the programming.
