Changed oil & filter, won't start now

[sloughboy]

Brought my 2007 Four Winns H200 out of storage (5.0l Mercruiser TKS carb), started it up (started right away) ran it for 15 minutes, all guages showed fine numbers, turned it off and changed the oil and filter. Now, the engine will turn over, but will not fire. Removed air filter off carb, poured in a bit of gas, and still will not fire. Oil pressure sensor seems fine (above the filter). Any advice would be appreciated.

An update, checked all fuses at front and main 50amp, nothing is blown. Also, some other related posts mention that I should hear the electric fuel pump turn on when I turn the ignition switch on...is this true? Gotta get my boat in the water this weekend....HELP!

I would slowly retrace my steps from the time you turned off the key before the oil change. Go over everything you touched, leaned on, wiggled, or even looked at. From there- pull a plug and check for spark. If you put gas directly into the carb and it still didn't hit, it has to be electrical since you bypassed the fuel delivery system.

check the dead mans switch bet you pulled it or the coil wire.

It is in neutral, yes? I guess it must be if it cranks. Hmmmm
