Abstract

A method is provided for detecting a malfunction in an electronically regulated fuel injection system of an internal combustion engine, by which effective limitation of the cause of the fault in a fuel injection system can take place. For example, it can be determined whether the cause of the fault lies in the low pressure system or in the high pressure system of the fuel injection system.
