No. Simply because once a jettison is initiated a control relay is energised thereby activating the O/J pumps. You have to remember this is a "2 man crew", no flight engineer to organise and concentrate on such operations. Once the jettison is initiated the crew would dial in a "fuel to remain" figure which will then be the point at which the jettison ceases. If the O/J pumps are not allready selected on, then they will be comanded to on.
