96 Spi no start/no spark

[Mike R]

1996 Spi started right up in garage after winter, ran about 1 minute on hose,
Took to ramp two days later, went to start before dropping in, and would not start, carbs rebuilt last august, with genuine mikuni kit by a mechanic, new fuel lines, ski ran amazing, no issues. Now won’t start, no spark, where do I start troubleshooting?
thanks, mike

If your ski responds to the start button and the gauge activated, I would look at the coil next. Check the connections to ground and the MPEM are good and clean. There is probably a resistance check in the shop manual to check the condition of the input and output coil.
