Abstract
In the operation of a fuel system of an internal combustion engine, the fuel is compressed by a fuel pump and travels by way of at least one fuel injection device into at least one combustion chamber of the internal combustion engine. It is proposed that at least periodically during a phase immediately when starting or just after starting the internal combustion engine, the fuel pump is actuated corresponding to an increased set point pressure. An increase in the set point pressure, however, is blocked if at least one blocking condition is met.
