Please help...My 1995 Yamaha waveraider was running fine and then I washed it down and put it away for a week. I tried to restart it before my next trip and it would not start. The engine will crank over normally but will only fire momentarily during the initial cranking. Even if I keep the starter on, the engine will not keep firing. I need to stop cranking and then restart it again to see a momentary fire. I have a mechanic that is not familiar with PWC's but can do some diagnostic tests. Will an owners manual help? Thanks in advance.
