I got the inside of your car wet and now it won’t try to start. Does it sounds like the computer (ECU) (since it is under the carpet). Would it make sense to buy a used one?

It was submerged there was water up to ankle depth inside the car. I did not check for spark, fuel pressure, and compression.
No, the check engine light does not work.

look at fuses first as it may have involved the fuse boxes and blew the main fuse.

look for many, many electrical problems from here. flooding does an enormous amount of long term damage to a car.
