2008 Toyota Yaris can’t start after flood

My car totally cannot start after flood and I already check manifold and oil engine, I found conditions still good. I suspect electrical and wiring, electronic device maybe fault.
please advise me

I doubt if you have full coverage on this 2008 but if you do contact your insurance . You can look for a shop that might get this going but you will have problems from now on. Vehicles just don’t survive floods well.
