Hi I got a 06 G35 coupe that will crank but not start. I got the car like this, previous owner tried to remove an aftermarket security system and didn't do it well. I removed the aftermarket system and join the wire that is needed to crank the car (this harness had some wires joined that weren't supposed to be. Its a white connector a bigger brown one near the brake paddle ). The ecu 15a fuse behind battery was blown as well as the dash fuse inside the cabin, but still no luck the check engine light is not on when I turn the key and obd will not connect . So I check for power to the ecu (with it unplugged) , I am getting power to pin 121 and no power at 119-120 which is should when I turn on the ignition. I do get ignition power to pin 2 however . I have another used ecu on the way (cheap enough to give it a try) just in case it is at fault. Any help would be greatly appreciated .
