How do I troubleshoot an issue with the Audi A1's engine not starting?

I just bought a used Audi A1 and I can't seem to get the engine to start. It cranks, but it won't actually start running. What should I do?

First, make sure that the battery is fully charged and properly connected. If that is not the issue, check the spark plugs and fuel system for any faults or damage. It is also recommended to have the car's computer system scanned for any error codes.

You might want to try putting the key in the ignition and turning it back and forth a few times, sometimes this can help prime the fuel system and get the engine to start.
