Abstract

La présente invention a pour objet un procédé de commande d'une pompe haute pression (20) de type digitale, le procédé de commande comportant les étapes successives suivantes lorsque le moteur à combustion interne n'arrive pas à démarrer durant la procédure démarrage : • vérification des paramètres externes du moteur à combustion interne ; • mesure d'un paramètre physique au niveau de la sortie haute pression (20_3), • application d'un signal électrique de commande de décollage (SD) en remplacement du signal électrique de commande à la pompe haute pression (20) durant la procédure de démarrage lorsque le paramètre physique mesuré au niveau de la sortie haute pression (20_3) est inférieur ou égal à une valeur de référence, • arrêt de la procédure de démarrage après un temps déterminé lorsque le paramètre physique mesuré au niveau de la sortie haute pression (20_3) est supérieur à la valeur de référence.
