My opponent has Wheeljack untapped and I have Skrapnel untapped. It's my turn and I flip Skrapnel to alt mode, then play I Still Function! to bring back Ransack in bot mode from the KO area. Then I attack with Ransack to Wheeljack, and after the flip of battle cards, Ransack is KOd. Does Skrapnels ability trigger because of Ransack getting KOd and make Wheeljack tap, letting me attack with Skrapnel?

You can do either, but not both. If you want to tap a character using Skrapnels flip trigger, you must KO Ransack before he can attack. If you want to attack with Ransack, it will be too late to flip Skrapnel to utilize his flip trigger.
