Remove the coils and ohm out the pins. Coil defect, igniter defect, harness defect, ecu defect. Did you run the plugs to long? Disconnect you replace plugs? With the right plugs? Coils take a different number than regular 4y plugs. 1500 hrs max or it will burn out coils. Disconnect the negative battery for 15 seconds. Check all connections in harness to coils. Check all fuses removed. Have to check continuity from G-28 to G130,141,132,133. #2 pin to G28. Pins 18,19,28,29. If harness is good then ecu issue. Battery positive is from fuse. Neg is from ground to frame. Igt1,2,3,4 is from ecu. These are the pin checks.

Verify connections and hook up negative. Start. If code is there then it's an ecu issue.
