My g35 had a revup Vq inside before it blew. I got a non rev 04 z Vq and swapped it into my g, (ecu, motor, trans, and wore harness) now I'm having staring issues. I checked no spark or fuel. And there was a 10amp fuse (engine control) blowing everytime putting the ignition just to the on position. Today I swapped the z harness for the g35 one and still nothing but the fuse no longer blows. Still no fuel or spark and noticed with either harness on, the check engine light never appears as it usually would with just turning the ignition to the on position. Anybody have any idea on how to go about getting my car back on the road lmk. Thanks

Wth? you can't used none rev engine with revup harness bro. Ecu is not even the same.
