Is Your 1999 Chrysler, Dodge, or Plymouth Minivan Acting Up?
If you’re experiencing frustrating issues like a persistent check engine light, rough idling, stalling, or a complete no-start condition in your 1999 Dodge Caravan, Plymouth Voyager, or Chrysler Town & Country with the 3.3L Flex Fuel engine, the root cause is often a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission shifting. When it starts to fail, it can create a cascade of problems that are difficult to diagnose and can sideline your reliable family vehicle.
From the Diagnostic Bay
We had a 1999 Caravan come into the shop that was a real head-scratcher. The owner said it would randomly stall at stoplights, but then start right back up. There were no consistent codes, just a general feeling that the van wasn’t trustworthy. We checked the fuel pump, ignition system, and sensors—all tested fine. On a hunch, we tapped on the ECM housing while the engine was running, and it immediately stumbled. A closer inspection revealed hairline cracks in the circuit board, a classic sign of thermal stress and age. Replacing the faulty module with a correctly programmed unit solved the problem instantly. It’s a reminder that sometimes the most complex electronic issues have a straightforward solution.
Common Symptoms of a Failing 1999 Chrysler ECM
- ✔ Persistent Check Engine Light (CEL) with various, often inconsistent, trouble codes.
- ✔ Engine stalling, stumbling, or hesitating, especially when warm.
- ✔ Rough or erratic idle that you can’t seem to solve.
- ✔ A complete no-start condition where the engine cranks but won’t fire up.
- ✔ Noticeable decrease in fuel economy.
- ✔ Harsh or incorrect automatic transmission shifting.
- ✔ Apparent loss of spark or fuel injector pulse.
- ✔ Communication errors with diagnostic scan tools.

How can I be sure my old ECM is the problem?
While the symptoms listed are strong indicators, it’s always best to have a qualified mechanic perform a full diagnostic. Common checks include verifying power and ground to the ECM and ensuring the communication network is intact. However, if other components like sensors, wiring, and fuel delivery have been ruled out, the ECM is the most likely culprit for these types of intermittent electronic issues.
