I can hear the fuel injection inside the car.
If you hear a humming noise, you could have a fuel pump issue. If you hear ticking, then it could be multiple things from a faulty fuel injector, to an engine issue. A diagnostic inspection of the noise from a qualified technician, such as one from YourMechanic, can help to determine the cause of the issue, and inform the best method of repair.
