Please Help
 

I have a Hyundai Getz 2005 petrol engine. The vehicle cranks but will not start. I have checked and replaced the spark plugs. A check was done by a friend and he informed me that the cam sensor was not working. I then replaced this sensor but the vehicle is still refusing to start. Could anyone give me some advise on what to do next please? Thank you

Don't just replacing parts, do some tests to try to find the problem?
Back to basic trouble shooting a no start condition.

See youtube video on how to do this
Here is an example

Scanner Danner is very good also.
