Abstract (en)
[origin: DE19908352A1] The invention relates to a method for operating a fuel supply system of an internal combustion engine, especially an internal combustion engine of an automobile. According to said method, fuel is conveyed into a storage chamber (17) and a pressure is generated in said storage chamber (17) by means of a pump (12,16). An actual value of this pressure is measured by a pressure sensor (21). The pressure in the storage chamber is then controlled and regulated to a desired value, any defect in the fuel supply system (10) being detected by a plausibility check. In the event that a defect is detected in the fuel supply system (10), a diagnosis cycle of the internal combustion engine is initiated, hereby activating diagnosis functions which test the operativeness of the individual components (18, 19, 21) of the fuel supply system (10).
