J90PLSSE Johnson V4 was running/idling along fine late one night and the engine stopped. I haven't been able to get it to run since. Apparently, there is no spark to the cylinders. I have inspected the plugs and they appear to be getting fuel. I checked the fuse; it appears to be good. The ignition safety switch was not operating properly so I changed it out. That didn't solve the problem.

I'm not a mechanic but i can change out parts if i know what part i need.

What's the most likely part to inspect/test and replace to restore fire to the engine?

Txs!

it would most likely be you power pack (cdi module) P/N 0586292 i would verify it is getting power to the module with a dmm but if both coils cut out i would assume its this. the only thing is there is no real way for you to test it the dealer would have to but if you lost all spark at once this is the most likely culprit. always trouble shot to the best of your ability a shop manual will show you how to test and troubleshot i would check and verify that all the coils, regulator/ rectifier, and stator are all in good working condition by testing them and if all is good most likely the cdi module
