ECU stands for either Engine Control Module or Electric Control Module. Either way, it's the computer that controls the fuel injection, ignition timing, and sundry other parameters that have to do with regulating the engine. If it's broken, the Check Engine light will illuminate, and the engine possibly won't run.

ECU is the Engine Control Unit. It is the "brain" of the car control pretty much every aspect of the engine running. If it were damaged the car would not run or run very roughly.

ECU stands for Engine Control unit. It is responsible for knowing when to turn on and off the various sensors and switches found throughout the automobile. If an ECU malfunction is suspected one should have a professional look at it as it can easily be shorted out.

ECU stands for engine control unit. It is basically the "brain" of the car. It controls all the engine functions like ignition timing and injector firing. When it goes bad it can cause very poor running or not start at all. Consult a qualified mechanic to see if it bad.
