Maybe, but nothing that could be heard over the rest of the racket the engine makes. The new spring did make an improvement in engine noise when running, though. Pure supposition, but my guess is that without sufficient pressure in the fuel gallery, the fuel elements don't fill completely, causing nailing.
If you're tracking down a rattling noise, there's about a million things it can be, including stuff that isn't rattling at all. Head to YT and listen to videos about injector nailing, important to be able to distinguish the difference. SOME rattle is normal, nailing is not.
