Wassup guys . I currently have a KA-T setup . I just got my ecu and injectors back from Jim Wolf. They flow tested my injectors to make sure it was all ok and also tuned my ECU.

So yesterday I installed the ECU , injectors and a z32 maf. The car started up put instantly puffed white smoke with a strong gas smell. I assume that it is running rich . I spoke with Jim Wolf and they told me to check a couple things.

The first thing that I did was pull off the fuel rail and injectors and turn the key on to make sure that there were no leaks and there wasnt any.

I remove the spark plugs and theyre all wet with gasoline.

The best way I can describe how the car sounds is PUT PUT PUT PUT PUT

Can you guys give me some advice on how to troubleshoot this problem ?

u might want to check your oil for fuel contamination, also prolly use different spark plugs since they can foul by being wet with fuel. check your maf wiring. a little search will find all your issues and how they were tackled. Good Luck.

Yeah just saw your other thread about maf wiring, theres your problem. i did the same mistake of wiring it incorrectly and car ran like shiat. Follow Jim Wolf document and make sure u solder and heat shrink tube all connections.
