With the riding season approaching, I figured I probably should try and fix one of my skis from last year. I also have a Polaris and Kawasaki I can ride while I wrench on this.
Ski in question is a 2005 GTi LE RFI. Has 200-something hours, but I installed a new engine and rebuilt the pump. Electronically, everything works.
The ski always had sort of a rough idle. However, once you hit the throttle it was smooth as silk and ran great. Also, usually after riding it you had to open the throttle a hair to get it to start. That might be an important clue. Last year, while out on a lovely river ride, the ski just quit running. It was as if the engine was shut off. It cranks, but won't start. Diagnostics so far have revealed that fuel is getting to the injectors, they are firing, and I do have spark. Rotary valve appears to be in time and does spin. MPEM does pulse the injectors on and off as verified with a test light.
My first impulse is to blame the injectors and/or fuel pump. No maintenance light or any warning indicators present. When I installed the engine, I replaced both strainer filters in the fuel pump assembly. The pump does come on when the key is inserted on the post and while cranking.
Any thoughts on this? Would like to fix it as it's a nice ski and will be a good cruiser in the summer.
