Crank no start and fuel on spark plugs

Hello,

You probably have oil in the spark plugs. Is the spark plug covered with "dark" fluid?
Usually if there is a leak in the valve cover gasket, oil can leak into the plugs.

Are there any trouble codes?

I have attached spark plug replacement as well and valve cover gasket replacement.
Let me know if you have any questions.

Thank you.
