I just bought an JDM 2jz motor trying to do a swap on my N/A. The problem I'm having is that there's no spark. It's getting fuel but no spark on either coils. Also I was wondering about an extra plug on the engine harness going to the ECU? It's a white plug that's connected to the ecu plug.plus the airflow sensor is not hooked up . there are some extra plugs on the wiring haress that i do no where goes.

Sorry for the confusing post. Ok I got everything done on the swap( engine harness for 6 speed,igniter,2jz MAF,resistor pak,6 speed ecu) but there's a white connector on the ecu connector that I don't know where it goes.

Dang, I cant believe no one is helping. Did you recheck all your grounds, and fuses. What ecu are you using, jdm or usdm?
