Ignition and control modules are the electronic brains behind precise engine timing — telling the ignition coils exactly when to fire and, on many vehicles, managing broader engine and powertrain functions. A failing module often shows up as a no-start, random misfires, stalling at speed, or an engine that cuts out when hot and restarts once it cools. Browse ignition control modules, powertrain control modules, and related electronic control units for cars, trucks, and SUVs to restore consistent starting and running performance.
