I'm trying to troubleshoot a no start condition on my '0615F. I have a manual for an '04 15F and it says to hold set and mode together for 3 seconds and then it will display codes. I get nothing when I do that. Yesterday, the ski started right up on the trailer but wouldn't start in the water. Once on the trailer it started intermittently a few times, then finally never started again. When it did run it ran fine. There is no spark or fuel on the plugs but there is 40psi at the rail, the main relay is working and the ECU is getting ground and battery power. I'm hoping there is a different way to access dealer mode for '06 otherwise it looks like i'm buying an ECU. Any info would be appreciated.
