Default 350z no spark crank no start completely stumped....

alright so i rebuilt my motor and when i attempted to start my car it wont start just cranks. red security light is solid on dash but i hear thats normal even when removing nats with osiris uprev....

i don't see spark when i attempted to crank the car so we'll start off there.

i tested for compression and compression is healthy throughout all of the cylinders.

changed out both fuel pumps

changed out both camshaft sensors, and crankshaft sensor

changed out spark plugs to new ones

i also got my ecu reflashed with osiris uprev to turn off the NATS and osiris uprev confirms that nats has been remove off the ECU

i am about 99% certain that i did the timing correctly on the timing chain with all the marks, i am 99% certain the flywheel is installed correctly i lined up the dowel mark behind flywheel with crankshaft mark at 12 oclock when installing.

i think the last thing i can think of is maybe the ECU is broken? but how can the ECU be broken if i can still connect to it with my nissan datascan software and run codes and what not.....

help me figure this out i have been at this for awhile......

the only code that comes up is U1000 i hear that code is normal since i swapped my z from auto to manual.....
