Abstract
A method of preventing an engine stall of a vehicle having a fuel injection device for pressurizing fuel stored in a fuel tank by a high-pressure fuel pump to transmit the fuel to a common rail, and injecting the fuel temporarily stored in the common rail into an engine through an injector may include steps of determining whether or not a drift occurs in an output signal of a high-pressure fuel pressure sensor for measuring fuel pressure at a downstream side of the high-pressure fuel pump, and performing a fuel pressure control by replacing a high-pressure fuel pressure value with a predetermined pressure value based on the output signal of the high-pressure fuel pressure sensor.
