I think you will find this link very helpful. Someone else appears to have had the same issue on a hyundai forum. I hope this answers your question.

have you check cam timing, has the timing belt jumped or has it broken and need replacing. does this have an anti-theft system on it and if so is it activated to cause no start. are the injectors working, have you check for codes in the computer is there is a problem with the computer. just some things to look into.

It's the sensor, it should be reprogrammed.

normally the cam/crank position sensor is the main source of control for the injectors as the cpu has to know the piston position before it allows any fuel into the cylinder for ignition Have the fault codes read. Replace faulty items. Use only genuine items as non-genuine replacement are not always compatible with the OEM fitted CPU units.

Any brand of 5W30 oil is fine. Just buy any decent oil (Castrol, Penzoil, etc.), but not any one labelled "Synthetic".

Coolant Temperature Sensor
