Can fuel injectors cause white smoke?
A Faulty Fuel Injector Without getting too technical, the injectors that deliver the fuel to the combustion chamber can leak or become stuck in the open position. This means too much fuel in the engine that needs to burn off and be expelled. This is seen as gray or white smoke from the exhaust.
What are the possible causes of the engine emits white smoke?
If your exhaust system is producing a thick, white smoke – you may have a problem. Many times, this thick smoke is due to the likes of a blown head gasket, damaged cylinder, or a cracked engine block, which is causing coolant to burn.
Can a bad ECU cause smoke?
Dark or black exhaust smoke is generally nothing to be worried about and is linked to the balance of combustion controlled by the ECU (Engine Control Unit).
How do you fix white smoke?

At the first sign of white smoke you can try head gasket repair treatment to seal the leak before you do serious damage to your engine.
Why is there white smoke coming out of my exhaust?
