No fire as in turns over but nothing?
Check the stupid stuff first, especially the kill switch. Then pull a plug and verify it's zero spark, and then pull and clean every electrical connection.

Usually when something electrical fails on that merc it'll leave some clue, like a burnt wire, or something melted.
