My car worked 100% fine directly before I tried to Reset the “your car needs regular service”, which has displayed for long time. I then tried to start car but it would not turn over. All Display Lights On etc. I know the display error Reset procedure made me turn the key on and off several times without starting the car itself, like I was “flooding” the engine and I guess that Display Error Message Reset process has obviously done something….HELP PLEASE

If it were mine and I was convinced the battery and starter were both fine, I would connect my OBD tester and see if there is a code in there that points to a easily addressed electrical fault.
