You do need a fully charged battery, and yes the ignition should be on, and do try it with the engine running.

This depends on the state of the battery, if one cell partially open circuit it may never charge, and also the output from the charger.

Trying to start a car with a poor battery puts a huge load onto the starting motor as the cranking amps go up, the same goes for a pump motor, if the voltage termed as pressure is low then the amperage will go up causing damage from the heat generated within
