Dear colleague, if the cylinders are filled with gasoline before starting it can happen that the injector does not close well and drip. If it is at the time of starting that the cylinders are filled with gasoline, it may be that the ignition is failing and having no spark in the spark plugs that the engine is drowning in gasoline, you should check the ignition, spark plugs, cables, coils, etc. To make sure that the spark is good you can disconnect a cable and install a spark plug with good dough to verify that the spark is good and strong when starting. If the spark were good and in all the cylinders it can happen that the refrigerant temperature sensor indicates a lower temperature, that is, within the working range that is lying, this causes the computer to inject gasoline too much thinking that the engine has the refrigerant with temperatures below zero.
