04 DE won't start after engine swap
**Before I explain my situation let me say that I have searched the forums constantly for weeks, and while I have found useful information I haven't solved my current issue.
I have an 04 350z 6 speed and about 6 months ago the engine went. I swapped in a vq35de non-revup out of a g35 Coupe automatic and just swapped over my clutch and flywheel onto the new-to-me engine in place of the torque converter. Still using my original ECU and harness. Once everything was back together the car would crank and crank but not start and run. I dropped the crank sensor and it started and ran, but very poorly. I assumed the flywheel was positioned wrong so I dropped the transmission and sure enough it was. So I lined it up correctly with the dial pin on the crank and put it back together. It still wouldn't start and run, so I dropped the crank sensor again and it fired right up. It ran and idled smooth. I don't see how it could be the flywheel again since I aligned it correctly this time, but it won't run with the crank sensor installed at all. Already replaced both cam sensors and crank sensor, and still nothing. Kind of at a loss here, if anyone has any info to help me it would be greatly appreciated, thanks.

Security system making it trip
Is your security system tripping or is you navigating system screen coming up and turning on ?
