Hi Guys Am New Here, I have A 04 G 35 2D, 2 Months Ago When When I Tried Starting my Car, all you can hear was starter turning, Battery was new had Power, and Car didn't start. All It gave me was The cranking Noise.. again and again...Everytime i Start The Car.. No Check Engine Light.. After A Couple Tries It car started, Someone Told me It was the Throttle Body, So i Change it, and It got fix, and after that my Check Engine stayed ON, And Today I went To start it and It gave me the Same Problem Again, now it Dos'nt Start..

Can It Be Crank Shaft position Sensors? Fuel ,Pump? Or Since i Change the Throttle I need to tune it so the Computer reads it.

Any Help You Guys Can give me ill Aprecciate it, Thanx Carlos

try this to relearn your throttle body.
so many things can be happening though with your problem. It could be anything.

 

Crank Shaft position Sensors that was my problem! Driver side.

 

Do u hear the fuel pump turning on?
