Common Symptoms of a Failing ECM

- ✔ Engine Stalling or Misfiring: The engine may stall for no apparent reason, run rough, or misfire, especially under load.
- ✔ Poor Fuel Economy: A failing ECM can’t properly manage the fuel-to-air ratio, leading to a noticeable drop in MPG.
- ✔ No-Start Condition: The engine cranks but refuses to start because the ECM isn’t controlling the ignition or fuel injectors correctly.
- ✔ Transmission Shifting Issues: On many vehicles, the ECM works with the TCM (Transmission Control Module), and a fault can cause harsh or erratic shifting.
- ✔ Loss of Power: Your truck may feel sluggish and unresponsive due to incorrect ignition timing or fuel delivery.
