Is Your 1998 Isuzu Hombre Running Rough or Not Starting At All?
If you’re dealing with frustrating issues like a persistent check engine light, poor fuel mileage, erratic shifting, or a complete no-start condition, the problem often points directly to a failing Powertrain Control Module (PCM). As the electronic brain of your truck, the PCM is responsible for managing everything from fuel injection and spark timing to transmission shift points. When it starts to fail, the symptoms can be unpredictable and maddening to diagnose.
Over two decades in the shop, I’ve seen hundreds of these specific PCMs on the GMT400 and S-10 platforms (which your Hombre is based on). The primary culprits for failure are almost always heat and vibration. After tens of thousands of heat cycles under the hood, internal electronic components like capacitors and solder joints simply wear out, leading to intermittent connections and faulty signals.
From the Shop Floor: A Real-World Scenario
“A customer’s ’98 Chevy S10 with the 4.3L V6 came in last week on a tow truck. It would crank but wouldn’t fire. The owner had already replaced the fuel pump, ignition coil, and crank sensor. After confirming spark and fuel pressure were present, we hooked up our high-end scanner and couldn’t communicate with the PCM at all. We checked the power and ground pins at the PCM connectorโthey were perfect. That’s the textbook sign of a dead module. We installed one of our pre-programmed PCMs, and the truck fired up on the first try. It saved the customer hundreds in further diagnostic guesswork.”
