Is Your 1998 Dodge Ram Running Rough?
If you’re dealing with frustrating issues like stalling, erratic idling, poor fuel economy, or a persistent check engine light in your 1998 Dodge Ram 1500, 2500, or 3500, a failing Engine Control Module (ECM) is often the culprit. The ECM is the brain of your truck’s 5.9L 360 V8 engine, managing everything from fuel injection and ignition timing to transmission shifting. When it starts to fail, it can cause a wide range of problems that are difficult to diagnose and can leave you stranded. Don’t let a faulty computer keep your dependable Dodge off the road. This direct-fit replacement ECM is the solution you need to restore your truck’s performance and reliability.
We had a 1998 Dodge Ram 2500 come into the shop that was a real head-scratcher. The owner complained of harsh, unpredictable shifting and a check engine light for a transmission solenoid circuit. He had already replaced the solenoid pack and even the transmission speed sensor, but the problem persisted. We checked the wiring from the transmission to the computer and found it was perfect. On a hunch, we connected our scope to the solenoid control wire at the ECM connector. We found that the computer was commanding the solenoid erratically, sending a garbled signal. The internal driver circuit inside the original ECM had failed. We installed one of our pre-programmed modules, and the truck was shifting perfectly within 15 minutes. It’s a classic case where the problem isn’t the part being controlled, but the controller itself.
Symptoms of a Failing 1998 Dodge Ram ECM
- ✔ Check Engine Light: The light is on, and you may have codes related to sensors, ignition coils, or internal module failure.
- ✔ Engine Stalling: The truck may stall intermittently, either while driving or at idle, and may be difficult to restart.
- ✔ No-Start Condition: The engine cranks but refuses to start due to a lack of spark or fuel injector pulse.
- ✔ Poor Performance: You may notice a significant loss of power, hesitation during acceleration, and reduced fuel efficiency.
- ✔ Rough Idling: The engine idles erratically or misfires, even after a full ignition system service.
- ✔ Automatic Transmission Issues: The transmission may shift harshly, get stuck in gear (limp mode), or not shift at all because the ECM controls its functions.
- ✔ Communication Errors: A diagnostic scan tool may be unable to communicate with the engine computer.

Frequently Asked Questions
Is this ECM truly plug and play?
Yes, absolutely. We program the module with your vehicle’s VIN and mileage before shipping. When it arrives, all you need to do is install it. No dealer visits or special tools are necessary for programming.
Where is the ECM located on my 1998 Dodge Ram?
The Engine Control Module is typically located in the engine bay, mounted on the right-hand (passenger side) firewall. It’s a silver metal box with three large electrical connectors.
What information do you need from me to program it?
During checkout, we will require your vehicle’s 17-digit VIN. This is critical for ensuring the programming is a perfect match for your truck’s specific configuration.
Will this fix my transmission shifting problems?
In many 1998 Dodge trucks, the ECM also controls the automatic transmission. If your shifting issues are caused by a faulty computer, this part is designed to correct them. However, it will not fix mechanical issues within the transmission itself.
Do I need to send my old computer (core) back?
