While it is possible, given ambient temperatures lately - it is less likely with a fuel injected car, but it CAN happen - simply not as prevalent as carburated cars of 30+ years ago.

Remember that for a gasoline engine to run it needs three things: compression, igntion and fuel. You might assume that the engine is fine (compression), but you could do a compression test & cylinder leak down test (to see if you blow a head gasket or cracked a head. There is a also a coolant test fluid you can use to see if you had any exhaust gas in the coolant (but as it mostly leaked out - you might not have very much of the old stuff to test).

You need to test for spark to see if you have a coil, plug or other possible issue.

You need to test that fuel is running and it coming out of the injectors. MAF sensor is less likely to have failed JUST as you overheated the engine, but anything is possible.
