Chris;
...yes...a visual which might stay with me a while too...we do what we have to...but your technique is actually a pretty effective "almost" normal operational test of D-Jet, including ECU, to show Injectors are flowing fuel when they should, and not leaking when they shouldn't...which is never!
Note: Applying full 12V to an injector is a mighty hard (and risky!) hit electrically, but it might just be what it takes to mechanically free up a stuck Pintle...but do this NOT many times, judiciously (very briefly ONLY!), and at your own risk!! A better technique for freeing up a stuck Pintle would be a solvent soak (I suggest carb cleaner, Marvel Mystery Oil mix), then applying 12V through a Dropping Res and momentarily, just like in normal operation!...no risk of hurting the Injector then! ...but if this does not free Pintle, I'd say OK to applying double voltage momentarily (by reducing DR to 2.5Ohms, and monitor Injector temp during tests!)...best practice is to NEVER apply a full 12V or continuous power...it's just too risky!
Cheers
