run fault codes and check for cam/crank position sensor. Check for cam shaft turning (Broken timing belt / chain). Check that the immobiliser is operational
If the security light is on, the anti-theft system may have immobilised the fuel pump from working. Different systems have their own way to immobilise the starting or ignition circuits. You need to check if that is a problem, might check with the dealer if it is a factory installed security system.
There is one method you ca try, first ensure the car is unlocked but with the keys out of the car. then disconnect the battery for about 2hrs, overnight if possible. this should reset the car immobiliser and ECU. When putting the battery back on connect the red first then the black i that order.
If no joy get back to me I have a few oher solutions.
If, when you switch the ignition on, you get a dash light on, the symbol is a car with a key overlaid, you have somehow activated the immobilser You could try disconnecting and reconnecting the battery, this may reset the immobiliser, If this does not work you will have to contact a Hyundai dealer to get the immobiliser unlock code.
There is a way to override the code, however you need the code number. The only other way is to sit in car with door shut, play with the central locking button on dash, locking and unlocking. While doing this occassionally turn the ignition on and off. If you do it long enough, you may find the immobiliser light goes out, if it does, quickly start the car.
