What do you do if your car wont start after driving through water?

Very hard to tell what's happened. If the intake got submerged under the water, you may have a water-locked engine. If so, pray to the god of engines that nothing is broken, take the HT-leads/coils out and then the spark plugs, and then try cranking the engine over a couple times.

If the electronics got submerged, wait for a few days for them to dry completely. Then, test again. If it doesn't work, go through a logical checklist; Starter motor, starter motor relay, starter motor fuse. Battery terminals, grounding to the bodywork, all engine bay electronic connectors, etc. Keep going.

Also, check your fuelling lines, too. That might have had water back-flushed through the return lines to the fuel tank or something else along those lines.
