2007 2GR-FE Help it won't start

I could use some help if the community is willing.

I was due for a tune-up and decided to do a bunch of upgrades at the same time. But something went very wrong and now the car start. I get everything like it wants to start but nothing, what I did find funny is the fan is on full blast like it's over heating. Tested the starter and it's fine but it's not engaging when I hit the button, not even a click. One major upside, my work has a partnership with a junk yard that only sales to repair facilities and it has several 2GR vehicles. I will be going there come Monday.

Now what I did and what went wrong along the way;

*RIPP Supercharger brand coils with E3 spark plugs, downfall every single coil plug broke and I tore the wires out of the rear camshaft position sensor or maybe it's a VVT-i sensor. I am not sure I got the wires back in the right spot. I did find a wiring diagram on the net I used but I am still not positive. This is the first time I have ever repined something.
*525cc injectors w/pigtail adapters and Radium fuel rail kit
*Upper and Lower intake manifold port matched and polished
*AEM air intake filter and system
*MaxBore 73mm throttle body
*R9K Tuned ECU - I think this might be the issue but I am hoping not.

Someone please help, also if you have other suggestions for parts to get for my car while I am there.

Either redo everything you even think you might have touched, especially wiring for starter since it won’t even click. If all else fails see above and return everything to stock. But first find out what’s going on with the starter.

I am thinking the engine immobilizer isn't allowing the car to start. Your Toyota ECU set a rolling 16 digit code between itself and the key. Obviously your new ECU does not know anything about this. As far as I have read the immbolizering functions of this system are on multiple SOC's and not just the ECU.
ALSO double and triple check your rewiring of the cam shaft position sensor.. That will definitely cause a no start issue. Of what you mentioned o think those are the only two that would cause or could cause a no start attitude.

I actually would like to add something to their write-up. While I was at the self pull yard getting the plug(which was not easy to find), I pulled the wire loom back and cut the wire 6 inches back. Now I can move the harness around a little bit making working on the back of that motor so mu easier.

Hope if someone runs across this post they find it helpful
