I need quick help, My 1997 1100 triple Yamaha waverunner isn't working properly. About a month ago when I hit the start button, nothing would happen, the engine wouldn't even rumple, just nothing, so I kept hitting it and hitting it over and over again until it would finally start. After the engine was heated and it ran for a little I had no problem. I had no other problems for a next 3 weeks, until yesterday when I changed the spark plugs. The start button wouldn't work at all again except this time it won't start no matter how many times I hit it. I tried putting the old plugs back (they weren't dirty or anything, I just like putting new ones in every now and then) and still nothing, so I took the battery out and charged it, and still nothing.... any sugestions?
