I have a 2004 350z with Vortech V3 set up, Orsiris tuned, DW 600cc injector, 255 fuel pump and boosting 7psi. around 380whp.
Everytime I start, I need to give a little gas or the car would die, the tuner said it because of the injectors.
This morning the car die on start because I didn't give enough gas, which usually I can just started again, but this time I can't start it at all, it won't crank, I try jump from another car or reset the battery but none of that help, and I can smell a little bit of gasoline.
Please let me know what I can do, thanks!

 

if you are pushing the pedal during cranking, you are leaning it out since the same amount of gas is injected and the TB is open more.

Thats why you smell gas. Your tune is poor. Get it redone without the excuses
