Obviously its not the CAS. Can you take a hi-res picture of the connector that has the CAS wires in it? I need a top and bottom pic so that I can see both rows of wires.

Yes I did, I have a custom stim that tests all aspects of the ECU, down to the radiator fans, A/C if built etc. Obviously I tested it thoroughly which is why I reported the problems I told you about in the PMs. I'm out of ideas right now and its getting late over here. I need to think more clearly, you don't happen to have access to a scope somehow? Friend's, at work, anything?

Just a note, when I did my ms2 I got 0 rpm output using the harness I built, but from a extra CAS I had hookedup directly to the ms2 I knew it was reading the CAS input correctly. I had found out my CAS wires on my harness I built were backwards. I had to flip them instead of ms2 ckp to ckp at cas. I had ms2 ckp to cmp at cas.
Hooked up backwards read no rpms, flipped to correct way worked out and read correct RPMs
ms2 set to 4g63

Right a breakthrough! Looked like it wasnt set to 4g63. Tuner may have changed it when he was trying to sense it. Not sure if he changed anything else though. Maybe send the base map again? Now receiving a crank signal and rpm though. Progress. Will do a composite log again.

Right so now we are gettin spark. All the gauges on main page are now working aswell, where we only had tps and fuel load before. Maybe just settings changed in the map that prevent startup......well hopefully!

Problem then was just fuel......but.......we just sent direct power to it............and it started!!! Queue mad celebrations haha!!
So just gonna wire a driect feed/relay to the fuel tomorrow on a switch in the dash.
Massive thanks to Reverant and everyone else for the help. Feckin tuner fiddling with it didnt help. Basically the problem was the CAS wires as said above, and the fuel. But CAS sorted now, and we can easily sort the fuel.
