What causes white smoke from the fuel injector?
The fuel injector is responsible for injecting fuel into the internal combustion chamber at the exact right time. If you were to have a bad fuel injector, then it would cause white smoke to form because the proper amount of fuel did not enter the chamber at the right time.
