I have a similar situation with the spark plugs not sparking when I test. I have fixed this problem several times with new plugs. It would work for a while but then it just starts failing again. So this time I replaced the coils with two different sets and I believe I have a working pair now after testing still no spark! I am going to check for whatever feeds the coils but I have not looked into the schematics yet. If you find a spark solution will you post it and maybe give me some more ideas!
