I have a 03 G35 coupe that sometimes Itdoesn't want to turn on I turn the key and it clicks but it won't start. After I pull it with a truck for little then it turns on! What can be wrong with it?

 

Dafaq? Pull it with a truck? Anyway, if it starts sometimes but not others or if it eventually starts after multiple tries its probably your starter selenoid or your whole starter.

 

Pulled with a truck like towed it. After that the car will start just fine

 

Like popping it in gear?

Will it start with the key sometimes?

 

You towed it with your truck?

I'm confused. Are you starting it in gear? Or just moving it around?

I'd venture to say you might want to get your charging system, or starter looked at

 

Or both.
So it just clicks when you turn the key and the engine doesn't crank? Sounds like battery. Once it gets "towed by a truck"' and starts, does it run a little rough? If so, again battery.
From behind a keyboard, I would suggest checking battery, connections and alternator.
As previously stated, check the charging system.

 

It starts after it's been pulled or pushed for around a quarter of a mile. By turning the key, like normal. Update today I was driving it perfectly out of no where slip VDC sign appear on dash and starts loosing power then I just starts stalling in a way am turns off.

 

Have you checked the battery voltage? Check it with the car off and again with it running, after you pull or push it for a quarter mile. Let us know the voltage readings.
What are you pushing with? People or a vehicle.

 

I had weird cranking issues, VDC lights, and normal drving conditions otherwise. I'm putting money on your CAM sensors. Replace both and see what happens in the auto zone parking lot.

 

I've changed the throttle body because slip VDC was comin up a lot. Now it doesn't do it as often but yesterday it came up and started stallin them turned of. I just ordered a fuse box maybe that's the problem? I pushed it with a truck.
