I have an older STI it has an ej20g, i recently changed the spark plugs and installed brand new coils, diamond f-645, however now there is zero spark. I tried using the older coils again and it has spark. The car ran fine before the swamp. i tested the new coils and they work (assuming I tested them correctly) my only thought now is it could be the ECU not letting the new coils work?? but i honestly have no clue! any help or ideas would be greatly appreciated!
