They should be closed. They should only be opening when the airplate opens - this mechanically opens the metering slits in the fuel head.
So , just double guessing this one - the pumps on has been a previous issue - but not noticed. Until an injector has failed to shut off .

Beat me to it Alan.
The metering slits have to be open in order to send fuel to the injectors. Stuck plunger maybe or misaligned metering arm hanging up. Tell-tell sign would be audible injectors squealing as soon as you turn the key on.
