A neutral coasting control (NCC) method based on fuel injection condition reinforcement applied to an NCC system is provided. The NCC method comprises in response to a controller detecting pressing of a brake pedal of a pedal system being switched to an NCC release from an operation, practice, or action of an NCC of a vehicle, fuel injection condition reinforcement control for delaying a fuel injection of a fuel injector. The delay of the fuel injection is according to a fuel injection stop condition for a predetermined time. The fuel injection delay is stopped according to a fuel injection stop abort condition and a fuel injection stop release condition. Fuel injection start control to stop or start the fuel injection according to a state of an engine overrun after transmission direct connection state is established such that improvement of fuel efficiency can be achieved by preventing an unnecessary fuel injection through delaying and limiting of the fuel injection start.
