Is Your GM Truck or SUV Running Rough, Stalling, or Showing a Check Engine Light?
If your 2003-2007 GM vehicle is experiencing frustrating issues like erratic idling, poor fuel economy, hard starting, or communication error codes, a failing Powertrain Control Module (PCM) is often the culprit. As the brain of your engine, when the PCM falters, it can cause a cascade of problems that are difficult to diagnose. Don’t let a faulty computer keep your reliable truck off the road. This is your direct, hassle-free solution.
From the Shop Floor: A Real-World Scenario
“A customer’s 2005 Silverado 2500 with the 6.0L came in on a tow truck last month. It would crank but wouldn’t start. He had already replaced the fuel pump and crank sensor, but nothing worked. After hooking up my scan tool, I noticed the injector pulse width was zeroโthe computer wasn’t telling the injectors to fire. A quick check of the PCM’s power and grounds confirmed they were good. The issue was internal to the module itself. We installed one of our pre-programmed PCMs, and the truck fired up on the first try. Itโs a common failure point Iโve seen hundreds of times on these otherwise bulletproof trucks.”

You can install this module yourself with basic hand tools. Most of these PCMs are located in the engine bay on the driver’s side, under or next to the battery. Follow these simple steps:
- Safety First: Disconnect the negative battery terminal and wait 10 minutes for the system to discharge.
- Locate the PCM: Find the module, typically mounted to a bracket near the battery or air filter box.
- Disconnect Connectors: Carefully unclip the wiring harness connectors. Inspect them for any corrosion or damage before proceeding.
- Swap the Module: Unbolt the old PCM and mount the new one in its place.
- Reconnect Everything: Securely plug in the wiring harnesses and reconnect the negative battery terminal.
- Perform Security Relearn: You will need to perform a simple key-cycle security relearn. This procedure takes about 30 minutes and does not require a scan tool. We include instructions to make it easy.
