Restore Peak Performance to Your 1997 Dodge 1500 5.2L
Is your trusty 1997 Dodge Ram 1500 with the legendary 5.2L (318ci) V8 engine suddenly running rough, stalling, or refusing to start? Are you battling persistent check engine lights and frustrating performance issues? The problem often lies with a failing Engine Control Module (ECM), the electronic brain of your truck. This replacement ECM is the definitive solution, arriving fully programmed to your truck’s specific VIN and mileage for a simple, direct-fit installation.
From the Diagnostic Bay
We had a 1997 Dodge 1500 come into the shop that was a real head-scratcher. The owner had already replaced the spark plugs, wires, cap, rotor, and even the fuel pump. It would start and idle, but under any load, it would sputter, backfire, and lose all power. The check engine light was on, but the codes were intermittent and pointed to multiple different sensors. After hours of chasing wires and testing components, we finally hooked up a lab scope to the injector drivers at the ECM. We found that the signal for two of the injectors was dropping out erratically. A quick swap with a known-good, programmed ECM like this one, and the truck ran like it just rolled off the assembly line. It’s a classic case where the central computer was causing ghost-like symptoms all over the system.
Is Your 1997 Dodge 1500 ECM Failing?
A faulty engine computer can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your ECM is the likely culprit:
- ✔ Check Engine Light: The light is on, and you may have codes related to sensors, misfires, or communication errors.
- ✔ No-Start Condition: The engine cranks but won’t start, often due to a lack of spark or fuel injector pulse.
- ✔ Rough Idle or Stalling: The truck idles poorly, stalls at stops, or hesitates during acceleration.
- ✔ Poor Fuel Economy: A sudden and unexplained drop in MPG can be caused by incorrect fuel and air calculations from a failing ECM.
- ✔ Erratic Transmission Shifting: On these trucks, the ECM plays a role in transmission control. Harsh shifts or failure to shift can be linked to the computer.
- ✔ Intermittent Problems: Issues that come and go with temperature changes are a hallmark of failing electronic components inside the ECM.

Frequently Asked Questions
Is this ECM really plug-and-play?
Yes. We program the module using the VIN you provide during checkout. This ensures it has the correct software and settings for your truck’s specific configuration, including engine, transmission, and emissions. When it arrives, you simply install it, and it’s ready to go.
Where is the ECM located on my 1997 Dodge 1500?
The Engine Control Module is mounted to the firewall on the passenger side of the engine compartment. It’s a silver metal box with large electrical connectors.
What information do you need to program the module?
We require your vehicle’s 17-digit Vehicle Identification Number (VIN) and the current mileage. You can typically find the VIN on your driver’s side dashboard (viewable through the windshield) or on the driver’s side door jamb sticker.
Will this fix my transmission shifting problems?
In many 1997 Dodge trucks, the ECM also contains the logic for controlling the automatic transmission. If your shifting problems are electronic in nature and caused by a faulty computer, this part will resolve those issues. However, it will not fix internal mechanical problems with the transmission itself.
Do I need to send my old computer back?
This listing does not require a core return. You can keep your old module or dispose of it responsibly.
Is this a new or used part?
This is a professionally prepared and tested original equipment part. Each unit undergoes a rigorous inspection and validation process to ensure it meets or exceeds factory specifications for performance and reliability.
