Abstract
The present disclosure relates to a computer-implemented method of controlling an engine fuel pump in a hybrid-electric vehicle. The method includes: cycling a vehicle powertrain between an electric mode, where an engine is commanded off, and a mechanical mode, where the engine is commanded on; depowering an engine fuel pump when the engine is commanded off; and determining if the engine is operating in a fuel shut-off mode.
