Have you checked all the fuses?

Well I figured it out. It was nothing wrong with my car. It was a set of counterfeit injectors sold on Ebay. So I wasted a shitload of time troubleshooting this.

I put in my old injectors and it fired up. I then replaced those with a set of re-manufactured index 12 injectors from FCP euro. Car ran like a top and then spun a rod bearing.

I just started getting this 30BB code after I had flash tuned my ECU with MHD 2+ put VRSF downpipes on it after I tuned it I took it for a spin and I hit the gas and there was several loud pops then the car started misfiring. After that I figured the tune blew the plugs out so I bought and installed one step colder performance plugs and coils off FCPeuro installed them and im getting misfires on cylinders 4,5 and 6 with a 30BB code not sure where to start only thing I can think of is possibly the MOSFETS?
