How did you break the caps in the first place? This could have something to do with them not working. Injector pintles are very fragile.

The truth is though that the pintle caps don't matter. They are only to protect the pintle, and if you want to you can just take them all off and run the injectors that way. Just don't drop them when you reinstall them.

As for getting pintle caps off it should be pretty easy usually. Grab yourself something thing but strong such as a razor blade and slide it between the top of the cap and the injector body and pry the cap off. For reinstallation it can be helpful to boil the caps first so that they expand and snap on with less resistance.
