95 Xplorer 400 no spark

Hello everyone, I have a story for you guys and hopefully I could get some help before I BURN THIS QUAD.

So I got this quad used and it ran like a top and always started good and ran excellent. After a day riding with my daughter we took em home and decided to wash our quads. My daughter washed her 95 Xplorer 400 which ran perfect and every since then now it won’t start. Since this happened I have visually inspected the wiring and saw nothing crazy. Replaced the coil with a new OEM one (one bolt holding it to frame)… replaced the stator and pickup coil with one from Ricky… took it to a atv professional mechanic to get stator installed even and afterwards he told me I need to replace the CDI module. Sooo, I bought a CDI module and replaced it and still no start!!!!!! Did some searching on the web and pulled the black wire for kill switch and still no spark, also pulled the black wire from CDI and still no spark. I have replaced the spark plug with a brand new NGK one also… I did notice the cap end on the plug wire is in very rough shape and has been taped up but was like that before and ran.

I am pulling my hair out and have a easy 600 bucks into this quad and it still wont run. PLEASE help me
