Abstract

A method for operating an internal combustion engine, in particular of a motor vehicle including at least one fuel pump delivers the fuel from a fuel tank into a fuel line. The pressure of the fuel, at least in a region of the fuel line, is increased as a function of an operating state. In order to assure a reliable starting of the engine, the pressure of the fuel, at least In the above-mentioned region of the fuel line is at least intermittently increased when the engine is not running.
