Abstract

An internal combustion engine controller includes a main processor for monitoring operating parameters of an internal combustion engine and a triggering device, working together with the main processor, for an electric fuel pump of the internal combustion engine. The triggering device works together with an electric activation device and operates so that the fuel pump is triggered essentially without time delay after actuation of the activation device. The internal combustion engine controller has an electronic switching device which operates so that, during an initialization process of the main processor, it triggers the electric fuel pump independently of the main processor.
