Looking for some trouble shooting tips..I have a 2004 Nissan 350z touring AT, the mod i have done is that of a pop charger. After i installed it, the car has worked fine for about 6 months. After that, when I try to start my car, it just keeps cranking over and over and wont start. after repeating this usually five or six times, it will finally kick on. so i cleaned the pop charger, it was dirty, and i thought that would fix the problem. to my avail, it did not help and i still experience the same problem? spark plugs? ignition? what do you guys think it might be?

Thanks for your help in advance!!!!

 

I'd check for spark first. I don't see your pop charger playing any role in this.

 

Depending on how dirty it was and how much debris got past it to foul the MAF, you may be in for some housekeeping. Remember, the aftermarket filters are not as efficient as OEM. Take it apart, look for oil and trash past the poop charger. Get a can of spray cleaner and clean the MAF. Either clean that poop charger properly, or reinstall the OEM air box with a clean filter and you're good to go.
