This video showcases a mechanic's experience diagnosing a Nissan Micra K11 that suddenly wouldn't start. To locate the fault, he proceeded by elimination, starting with a fuel issue.

He checked the injectors and spark plugs. He found that the cylinders were "flooding" too much (his words), receiving too much petrol.

He replaced components such as the fuel pressure regulator and injectors without success, wasting time following incorrect advice from the internet, such as cleaning the throttle body. In this case, he also achieved no results.

Finally, after conducting a methodical check of the system, he discovered that the injectors were not receiving power. The problem was incredibly simple: a blown fuse, which, when replaced, allowed the car to start immediately.

The advice is not to rely solely on internet diagnoses but to narrow down the issues with logical diagnostics, or you will only find confusion.
