| plug that's exposed and grounded. Doing this for more than 1 coil pack just to be sure its not that specific coil pack with issues. If still no spark - you'll need to get out the car's electrical diagram and start checking for voltage readings at the PTU (is it getting power?). The CPU causes the PTU to fire each coil pack. You've also checked both the engine bay fuse box as well as the fusible link box (in front of the battery)? That's the other obvious thing to verify - best to do the fuses with a meter just to be sure there's an electrical connection when ignition is turned on (but engine not running). Fuses sometimes look visually OK but are not.
