The engine control module is the computer brain that manages fuel injection, ignition timing, emissions control, and other critical engine functions. ECMs commonly fail due to electrical surges, moisture damage, or component wear over time, causing poor performance, stalling, or no-start conditions. A functioning ECM is essential for proper vehicle operation and emissions compliance.
