Generally a "no fire" problem on a 30 Evinrude, can be narrowed down to either a faulty power pack, or stator assembly. The stator can be checked for voltage output with a voltmeter, (around 180v min.), while to check the power pack, the process of elimination is used. One other consideration, on the electric start model check for a shorted key or kill switch. This can be achieved by simply unplugging the remote harness at the red cannon plug on the engine, and spinning the engine over while checking for fire at the plugs.
30h = 110000b
