A Technician’s Notebook: The Intermittent No-Start Nightmare
A few months back, a local delivery company brought in their 2016 Express 2500. The driver’s complaint was maddeningly intermittent: some days it would start perfectly, others it would just crank and crank. They had already replaced the battery and checked the fuel pump. After hooking up my scan tool, I noticed communication with the ECM would drop out randomly. On one of the no-start events, I confirmed power and ground to the module were good, but it was completely unresponsive. This pointed directly to an internal failure in the original ECM. We installed one of our pre-programmed modules, and the van fired up on the first try. It’s been in service ever since without a single issue—a testament to how a reliable 2016 Express 2500 ECM can solve even the most frustrating electrical gremlins.
A Straightforward Guide to Installation
Replacing the ECM on your van is a manageable job for a DIYer or any professional technician. With our pre-programmed module, you eliminate the most complicated step. Follow these general guidelines for a successful installation.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the ECM: On the 2016 Express 2500, the ECM is typically found in the engine compartment, on the left-hand (driver’s) side, often near the air filter housing.
- Disconnect Connectors: Carefully release the locking tabs on the wiring harness connectors and pull them straight out from the old module. Inspect the pins for any corrosion or damage.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket. Keep the hardware as you will reuse it.
- Install the New Module: Mount your new, pre-programmed ECM onto the bracket and secure it with the original hardware.
- Reconnect Everything: Firmly plug the wiring harnesses into the new module until they click into place. Reconnect the negative battery terminal.
- Final Check: Turn the key to the ‘On’ position for 10-15 seconds before starting the engine. This allows the vehicle’s other systems to recognize the new ECM. Start the engine and check for proper operation.

How do I provide my VIN?
How do I provide my VIN?
After you complete your purchase, you will receive an email with instructions on where to send your VIN. Alternatively, you can add your VIN to the ‘notes’ section during checkout. We cannot ship the module until we receive your VIN, as the programming is specific to your vehicle.
Is any additional programming needed after installation?
No. This ECM comes fully programmed with the latest GM software for your specific VIN. In most cases, it is a plug-and-play installation. Some vehicles may require a simple security relearn procedure, which can be done without special tools and instructions can be provided.
Will this fix my specific problem?
This module will correct any issues directly caused by a faulty ECM. While the symptoms listed are very common for ECM failure, we always recommend a proper diagnosis by a qualified mechanic to rule out other potential issues like wiring or sensor faults.
What if I order the wrong part?
We strongly encourage you to match your original part number or use our detailed compatibility list. Since each module is programmed to a specific VIN, returns for incorrectly ordered parts may be subject to a restocking fee. If you’re unsure, please contact us with your VIN before ordering, and we’ll be happy to verify fitment for you.
