A method for function control of a high pressure pump (5) in a system for fuel injection in a combustion engine: The method is carried out during stationary operating conditions in the combustion engine, with a constantly requested reference value for the fuel pressure in an accumulator tank (6). A feeding pump (2) in a low pressure part (3) of the system is controlled so that the fuel pressure in the low pressure part at the inlet to the high pressure pump falls, and at the same time this fuel pressure is measured, as is the fuel pressure in the accumulator tank. The development of the measured fuel pressure in the accumulator tank is compared to the reference value during the pressure reduction in the low pressure part, for the generation of information about the high pressure pump's functionality. |
