Abstract
The invention relates to an electronic engine control (EEC) equipped with a fuel cutoff safety device in the form of a relay 12 for controlling the winding of the fuel pump 16. A single conductor (FCOM) connects the fuel pump power supply line with the EEC in order to test and/or monitor the voltage applied across the terminals of the fuel pump, at least when the engine is started up.
