A method of cold starting a hybrid electronic vehicle is provided to solve a problem of start fail due to the cold start by resetting and calculating a power limit value required for the cold start according to an output limit value of an SOC and an SOC capacity. A power limit value required for cold start is reset in accordance with a power limit value of an SOC(System On Chip) and an SOC capacity. The output limit value of the SOC is compared with the output value required for the cold start, and then a power limit value to be output when an engine start signal is output from a hybrid control unit is a final output limit value, if the output limit value of the SOC is high. If the output limit value of the SOC is low, a safety diagnosis search is put off during a predetermined time.
