Method for operating a high-pressure injection system (1) for a combustion engine (8), comprising the steps of: conveying the fuel by means of a conveyance pump (3) to a high-pressure pump (2), conveying the fuel by means of the high-pressure pump (2) to a high-pressure rail (10) under high pressure, and conveying the fuel by means of the conveyance pump (3), before starting the combustion engine (8), to the high-pressure rail (10), wherein the conveyance pump (3) is operated in two different conveyance directions, and in a first conveyance direction the fuel is conveyed to the high-pressure pump (2), and in a second direction opposite the first conveyance direction the fuel is conveyed into the high-pressure rail (10) before starting the combustion engine (8). |
