Check the coolant temperature sensor for the ecu . If it is giving out an incorrect signal then the ecu will not richen up the fuel mixture for cold starting. And it will assume the engine to be at 50 deg C. It should have a resistance of 2500+ ohms for a cold engine. And around 300ohms for a hot engine.
