Feel sorry for you; I hope you have another transportation.
I wouldn't rush changing the oil until the engine finally starts or the problem is found.
If some more fuel or water leaks into the fresh oil, it would be ruined and you will need to replace it again.
Another test that can tell you if and what valves may be leaking (read the last paragraphs):
