Hello good sirs. My fiance's sonata died while she was driving it. It would crank and start for a second maybe two.

I got an obd2 reader but its showing there are no codes to read. Not sure what to try, I will be retrying starter fluid into the air intake in the AM.

I wouldn't recommend starter fluid....not since big old carbonated engines. There are a lot of things you can check. When you get crank and no start it can be computer driven for the safety of the engine, but would usually then throw a code. Otherwise, you need fuel, air, and spark. For this I would start with the fuel. Sounds like the fuel pump may be going out, got enough pressure/fuel to start, but not keep it running.
