Is Your GM Vehicle Running Rough or Not Starting?
If you’re behind the wheel of a 1999-2002 Camaro, Firebird, or even a workhorse Silverado or Sierra from that era, you know the power and reliability they’re capable of. But when the brain of the operation—the Powertrain Control Module (PCM)—starts to fail, it can cause a host of frustrating and confusing problems. In my 20+ years in the shop, I’ve seen failing PCMs turn perfectly good vehicles into driveway ornaments overnight.
You might be experiencing issues like a sudden no-start condition, erratic idling, stalling for no reason, poor fuel economy, or a check engine light with a cascade of unrelated trouble codes. Often, these symptoms point directly to a failing PCM, which can be damaged by years of heat cycles, vibration, and electrical stress.
The Direct-Fit, Programmed Solution
This isn’t just a generic replacement part. This is a Powertrain Control Module, part number 19109040, that we program specifically for YOUR vehicle using your VIN. This crucial step ensures that the module has the correct software for your engine, transmission, and all factory-installed options. We load the latest stable updates from GM, which can often resolve underlying drivability issues the original software had.
Expert Pro Tip: Don’t Forget the Relearn Procedure!
After installing your new PCM, your vehicle’s anti-theft system (VATS/Passlock) will need to be synchronized with the new module. This is called a Security Relearn procedure. It’s a simple process you can do yourself in about 30 minutes with just the ignition key—no special tools required. This step is critical for allowing the engine to start and run. Skipping it is the #1 reason I see for post-install ‘no-start’ calls.
Why VIN Programming is Essential
Ordering a PCM without VIN-specific programming is a gamble. A module from another vehicle might have software for a different engine, transmission, or axle ratio, leading to poor performance, incorrect shifting, and persistent check engine lights. By providing your VIN at checkout, you guarantee:
- ✔ Correct software for your exact vehicle configuration.
- ✔ The latest GM calibrations for improved performance and reliability.
- ✔ Proper communication with your vehicle’s other modules.
- ✔ A true plug-and-play installation (after the security relearn).
Broad Compatibility Across the GM Lineup
While this is a core part for the 1999-2002 5.7L V8 Camaro and Firebird, this versatile PCM was also the factory-installed brain for a wide range of popular GM trucks and SUVs. This module is a direct replacement for part numbers 19109040, 09354896, and 9354896.
This part will fit the following vehicles (please verify your part number):
- ✔ 1999-2002 Chevrolet Camaro (5.7L)
- ✔ 1999-2002 Pontiac Firebird (5.7L)
- ✔ 1999-2000 Chevrolet Corvette
- ✔ 1999-2000 Chevrolet Silverado 1500/2500 (8-Cylinder)
- ✔ 1999-2000 GMC Sierra 1500/2500 (8-Cylinder)
- ✔ 2000 Chevrolet Tahoe (Silverado Style)
- ✔ 2000 Chevrolet Suburban 1500/2500
- ✔ 2000 GMC Yukon / Yukon XL 1500/2500
On the Camaro and Firebird, you’ll typically find the PCM located behind the passenger-side strut tower in the engine bay. On the trucks and SUVs, it’s usually found on the driver’s side, under the battery tray. Always disconnect the battery before beginning installation.
