Im helping a freind get his Yamaha jet ski running after sitting for two years on the trailer. (I do not recall specific model or year of unit, kinda on the small side). It had a full tank of gas which was like varnish so we drained it, blew out the fuel lines with air, refilled it with 93 octane and tried to start it. It did not want to start so we gave it a little gas in the carbs and it started and idled for about a minute, during that time he turned on the water hose and it died when i tried to rev it up. It started back up itself then ran good and reved up for about 30 seconds then died again. When it reved up it smoked really bad blue smoke (oil) until it died. During our efforts to restart it we left the water running by accident when the engine was off, what could this have done? I pulled the plugs and noticed they were wet so i dried them off and i put commpressed air in the cylinder and it made water come out of the impeller area?? Whatever we do now it will not even attempt to start unless we put fuel in the carbs, then it will run for about thirty seconds and die. How do i check a fuel pump on this thing, and where would it be. Its strange how it ran fine for a minute then now it wont start. It seems like a fuel supply issue but what could it be?? I do have spark and i must have compression as it will fire when we give it gas in the carbs. HELP!!
