So I have a 08 g35x and there is no power to any components it's push to start and it doesn't even start no dash no locks the key fob doesn't work won't jump with a booster pack battery fuses are good any ideas

 

The starting circuit is fairly complicated, failure of the fuel pump, bank1 or 2 cam sensors, crank sensor, can all cause the vehicle to NOT START. If you're proficient with technical manuals you can read the factory service manual here:

When you say "there is no power to any components" do you mean even the dash lights won't turn on? If so then clean the battery terminals with a wire brush and get the battery tested, might just be a bad battery (a jump pack won't do **** if the battery is fried).
