problem putting neo in r33 s1

hi all i have dropped a neo into my r33 s1 but cant get it to fire compression is great engine cranks i have spark i can hear the fuel pump prime when i remove cas and spin it by hand i hear the injectors click i am using a s2 engine loom and tried multiple s1 and s2 ECUs i have swapped vct plug and repinned the cas plug in opposite order i bought the engine as a s2 rb25 but after closer inspection it seems to be a neo with a s2 intake manifold/throttle body/hot side. any1 got any ideas?

You reversed the wiring on CAS?

[KiwiRS4T]

Which CAS do you have - R33 is metal with Mitsubishi logo Neo is Plastic Hitachi unit. And what injectors are you using?

[WMDC35]

Sounds like a late s2, which tps? Have you tried unplugging it?

It has the black neo cas ! neo timing belt cover and a neo vct solinoid coil packs are neo and mounted like a neo with no brackets

Not too sure. The s2 loom plugs into it.have not tried unpluging it

Black cas

Look like standerd s2 injectors

Unplugging tps does nothing

[WMDC35]

Have you tried getting it to fire on engine start? Would rule out low fuel pressure etc

I had to change the coil pack to ecu wiring when i swapped a neo into my s1. That was with an s1 loom however.
