In the owner manual, the one supplied at purchase, there is a page that has all the error codes listed and the usual means of diagnosing the fault and the remedy. If you don't have the book then you should go to your local Yam dealer and get it on their diagnostic machine, that will tell you what the problem is and they can fix it right there. You can't do any more till you either have the owners manual or take it in, All the info you have supplied tells you exactly what's wrong, if you don't want to believe it then there's noting anyone can say. No one on here can tell you how to fix it that's something you have to do yourself. Take the master key and get it cut then take your ECU and coils off the bike, send them or take them to be tested, there is a way to test your coils at home but truth to tell if your ECU is gone then no matter how often you check them it ain't going to run till the fault on the ECU is sorted.
