Abstract

A method and system of handling starting failure of a vehicle are provided. The method includes detecting, by a controller, a failure occurring in vehicle starting and sensing, by a voltage sensing circuit, the voltage value at at least one point on a fuel pump circuit. In addition, the controller is configured to calculate the current amount based on the sensed voltage value and analyze the cause for the starting failure based on the current amount and the traveling state of a vehicle. Then, the controller is configured to output the handling information for the failure cause.
