no spark

[klamhead]

I have a 1995 evenrude 90 hp which ran perfectly until now. Last time at the lake it started right up and ran for 5 seconds and shut off, and would not start. Fuse in motor compartment is good and i replaced the power pac Still wont start. I pulled a couple of plugs and turned over and dont see any spark. Any suggestions?

Disconnect black/yellow wire from power pack and recheck for spark, if has spark then have bad key switch, stop switch or harness. If no spark then test output of source coil, trigger coils and power pack with a peak reading voltmeter to find failed part.
