Hello so during my research, I have come across so many people saying that the solution to fixing the crank no start problem by changing the cam (passenger, driver) sensors as well as the crankshaft sensor. So today, I have changed all three using the Hitachi brand; and it still did the same thing. I have tried resetting the ECU, and the other additional relearning steps like for the throttle body. I even bought a new battery to test and even put a gallon of gas into the car. Last year, I changed the fuel pump, throttle body, and MAF as they are brand new technically. I have checked the fuses by the battery and did not see any of the fuses blown.

The G35 was running before and just stopped starting again. The main issue before was that when I cranked it, it would start and immediately shut down. I drive an automatic sadly.

Any suggestions?

 

And the battery is putting out the correct voltage right? You can buy bad new batteries

 

yeah I checked the voltage and it said 12.4V. I might try use electrical cleaner for my sensor terminals but there’s really nothing else I could do

 

U sure your fuel pump works? Try spraying some starter fluid into the intake as you crank the engine. See if it tries to start like that.

 

Yeah it did start. After I did it though I seen some white smoke coming out of my engine.

 

Exhaust* not engine

 

when I had this issue it was because the relay on the IPDM went out that controls the Fuel pump.
