Well, to clarify, a leaking injector would leak until there was no more pressure. Normal ones only leak down until the pressure drops below the spring loaded pintle valve threshold, but they don't leak down after that. The fuel accumulator's very job is retain some line pressure up against the injectors for an hour or two to help with a fast warm restart.
