I have a 2015 elantra that was parked for 2 days. When i tried to start it it fired
up and ran for about 1 second and then quit. Then it cranks like it has no
compression  It is obviously flooding and washing down the cylinders cause
once it sits for a while it will try to start again for about a second and then do the
same thing  Does anyone know of any problems to cause ths?

Leaking fuel pressure regulator is the most common but have also seen injectors drip fuel enough to flood and engine. Change the oil and filter once you have fixed it.

i replaced the fuel pressure regulator with a complete fuel pump assy and also pulled the fuel rail and tested the injectors , Any other ideas?
