03 350z shell. Dropped a motor and transmission in it from 04 infinity both motors (DE) same motors.
Was told the ECM and Wire harness I was given were from stock 350z original motor.
Good compression believe the timing is fine, flywheel fine.

Getting 12V to the coil pack but no spark..
all sensors have been replaced. crank o2 etc
I believe all grounds are connected. I cant seem to find a good drawing for all the ground connections to verify that I'm not missing something small there.

I've been told that an ECM Flash might be the way to go but I don't want to pay to have a flash and still have a non running car. Unless that could really be the fix.

Any help or suggestions would be appreciated, I've been at this a little while now.

If you go down 4 threads there is a kid having the same issue. Maybe you can read that thread and or work with each other to figure stuff out.

thank you!
I actually uninstalled the flywheel and clutch and reinstalled them to factory spec and got the car to fire. So for now I'm on to putting it all back together to see if she runs good after inserting all the sensors and reinstalling the transmission.

Update: car only starts when the crank sensor is completely removed from the wire harness. As soon as it's reinstalled the car returns to crank no start. Replaced sensor with OEM and still no start when the sensor is installed.
