The correct cold starting procedure for fuel injected cars is to keep your foot _off_ the gas. The system is designed to inject the correct amount of fuel for the amount of air that is being drawn in with the throttle closed and the cold start air valve open. Some of the old mechanical systems, like Alfa, Mercedes or the early BMW 2002 tii (later ones used Bosch injection) would flood if you touched the gas before cranking.
On a warm engine you may have to give it _light_ throttle, but _never_ start an engine with the pedal to the floor, unless you're trying to clear a flooded engine. Starting it at full throttle burns up bearings because you are racing the engine before the oil pressure is built up.
The reason for stepping on the gas in a carbureted car is to set the choke, and it also gives a shot from the accelerator pump. If the carb is set correctly, you should only have to step on the gas once to set the choke, then it should start with your foot off the pedal.
