Is Your Truck Running Rough, Stalling, or Showing a Check Engine Light?
If your 1998 Isuzu Hombre is experiencing frustrating issues like poor fuel economy, erratic engine behavior, or a persistent check engine light, a failing Powertrain Control Module (PCM) is often the culprit. As the brain of your vehicle’s engine and transmission, when the PCM starts to fail, it can cause a cascade of problems that are difficult to diagnose. You need a reliable, straightforward solution to get your truck back in top form.
This is a dependable, used OEM engine computer that is fully tested and ready for installation. We take the guesswork out of the repair by programming the module specifically for your vehicle using your VIN. This ensures it has the latest GM software updates and communicates perfectly with your truck’s systems right out of the box.
Expert Pro Tip: Check for External Faults First
In my 20+ years of diagnostics, I’ve seen countless PCMs for these GM trucks get replaced unnecessarily. A common misdiagnosis is blaming the PCM for a no-spark condition when the real problem is a faulty Ignition Control Module (ICM) located under the distributor cap or a corroded main engine ground. Before you condemn your computer, take 10 minutes to ensure the main ground strap from the engine block to the firewall is clean and tight. A poor ground can mimic a dead PCM and is a much cheaper fix!

Plug-and-Play Installation: Get Back on the Road Fast
Replacing the PCM on your Isuzu Hombre (or compatible GM vehicle) is a straightforward process. Here’s a simple guide to get it done:
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the PCM: On most of these trucks and vans, the PCM is located in the engine compartment, typically on the driver’s side inner fender or near the battery.
- Disconnect the Connectors: Carefully unclip the wiring harness connectors from the old PCM. Inspect the pins on the harness side for any corrosion or damage and clean them with an electronics-safe cleaner if necessary.
- Swap the Modules: Unbolt the old PCM and remove it. Mount the new, programmed module in its place and secure it with the original hardware.
- Reconnect Everything: Firmly plug the wiring harnesses into the new PCM until they click into place. Reconnect the negative battery terminal.
- Final Step: Your vehicle may need to complete a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes. Your vehicle is now ready to start.
After purchase, please send us your vehicle’s 17-digit VIN. This is essential for us to program the computer correctly before shipment. This ensures a hassle-free installation and restores your vehicle’s performance and reliability.
