If you carefully ground all the plug bases with a wire wrap on the threads you probably won't blow the DI. If you want to look at the spark on an engine display scope leave the plugs in the head, make jumper wires with ends male and female on each jumper and lay the DI over. Clamp on the pickup clamp to each plug wire. Saw this from a picture of the R&D setup on how the DI was developed only the DI was suspended about .6 m above the test stand engine and the extension jumers went straight up from the plug to DI.
You might have fuel pressure problems. Several postings on this.
Cold start enrichment is done by ECU by dithering the injector dwell times. Might be worth a trip to a shop with ODBII reader to do the diagnostics.
