This is a used car. I turned on some lights, heating and radio Bluetooth to make sure they were working properly. After 10 minutes I started the car, it cranked but did not start. All of the indicators popped up on the dashboard. I tried several times but it’s the same.

Hello,

If the engine is cranking over strong but not starting, it could be due to not getting fuel or spark. It can also be due to low compression.
When the ignition is in the on position, can you hear the fuel pump prime for a few seconds?
One way to check if it is a fuel related issue, is to spray starting fluid into the intake and try to start. If the engine starts and runs for a few seconds, then you will know that the issue is fuel related.

Take a look at this helpful guide, it goes over the usual crank no start issues:

Let me know if you have any questions.
Thank you.
