My fearless prediction? Your plugs are out of gap. If not, then the battery's a bit tired.
If the plugs are out of gap, make sure to fix this issue because this can stress the already-suspect DI cassette, and eventually lead to a myriad of other running issues. Regapping to proper spec should help, but if the plugs are old, you should plan to replace them too.
If the plugs aren't out of gap and are relatively recent, then the battery would be my next candidate. If it's low on juice, it may have enough to crank the engine but not quite enough to generate adequate spark.
2.3s often do take more cranking because with fewer cylinders it can take more time before one hole has adequate compression to fire off. But several seconds under ideal ambient conditions like yours is excessive and indicates a problem somewhere.
