Make sure the brown wire from pin 4 of edis module has a good earth, I put mine straight to battery neg. Without that you'll have no spark at all. Check condition of cps plug and wiring. And also I think im right in thinking that the injectors and coil packs share the same earth wires? Can someone confirm this? Thats how my rs2000 is wired up anyway and it runs fine, (both pretty much the same loom layout, rs2k and xr3i). without these ^^ earths wired to the correct pin in the ecu you wont have a hope in hell of startin it.
Check it out let me know how you get on. I used a good website for the pin locations when doing mine, il try and find a link for you

This seems to be a good bucket full of info on the same conversion ur doing. See if it helps
