There are a lot of things going on inside your engine and before it warms up it isn't producing reliable horsepower. If your car won't run until it warms up it means that the fuel air mixture is not rich enough. A colder engine requires a richer mixture. Older cars did it with a choke on the carb. Newer cars do it by the computer adjusting the fuel/air mixture and engine timing to until it watms up. If your car is mid 1990's or later you probably have a problem with a sensor.
