no start on my 33 swap

swapped a 33 into my impreza and have been unable to start it.
i have spark,fuel,and compression...
ive checked my engine timing 5+ times.. dead on using every diagram and knowledge i know.
ive tried a known good ecu...
ive tried different cam/crank sensors...
ive checked grounds many times..
my compression is around 140psi on all cyls.. (i have low comp ratio)

I didnt use a svx wiring harness, i had legacy wiring harnesses and put together my own custom harness using mitchel and alldata wiring diagrams.

Anyone have some ideas for me to try? It just cranks and the very few times ive seen it try and start it sounds like bad timing/misfiring.. i have clean plugs on cyl 1 and 4.. other plugs are black.

Can you elaborate what you did with the wiring harness? Are you running a second legacy igniter or an SVX igniter?

I just pretty much made my own wiring harness, fuel pump works, ecu turns on.. I have spark.. etc. I've looked over my wiring sooo many times I am so confused. I'm using the svx igniter.

Correct firing order? I know it's kind of dumb but hey simple things first... Had a starion last night said his mechanic changed his plugs/wires we looked at them and replaced them cause i knew it was bullshit and it runs 1000x better. Simple things my friend
