Hello,

Thank you for sharing the fix for the issue that you had.

A faulty ignition coil will stop the spark plugs from producing any spark.
one of the common reason for coil failure is having moisture getting inside the coil and cause corrosion. Which will lead to the coil not functioning properly.

I have attached diagrams for anyone who might be having the same issue.

Please let me know if you have any questions.
Thank you.
