My guess is that the ball (steel) has corroded - not unusual. The solution is to replace the steel ball with a ceramic ball. There are several sizes, so make sure you get the right one. The spring will also corrode and eventually break, so get some of them too.
Are you saying that the new injector is also not working? Did it ever work? If not, make sure that the arrow on the injector points in the direction of the flow.
Have any of you ever heard of USLBA? Got an email this morning announcing I had been selected for this award.
