Hi it’s exactly what the title says my brother has a 2003 g35 coupe while we were driving the car shut off randomly like while the car was moving ignition wouldn’t even try turning on like car lost all electricity no lights were working anywhere we pushed it to a gas station and put in 10$ which was no luck then we pushed it home the battery is not the problem as it had spark and we even tried jump starting it but that didnt work what can be the problem?

 

Without reading for codes or a bit more troubleshooting, you are going to get remote guesses.

Crank sensor, cam sensors...whatever

If you can't read codes, best get a Forseal wifi OBD connector from Amazon and load the Torque Pro app on your phone.

I have a connector in each of our three cars.
