Rb20 swap wont start.. possible ecu problem? CAS?

[lilskyline240]

Alright so i finally got the Rb20 wired in the 92 hatch and we ran into a problem. When you rotate the CAS the injectors nor the Coils fire... So i thought the CAS was bad and tried the CAS on my motor and it worked fine.. So i proceeded to check the voltages coming from the harness.

Wire 1 ~ bouncing 0-5v as shaft rotatesWire 2~ bouncing 0-5v as shaft rotateswire 3 ~ 12v wire 4 ~ ground

so im thinkin maybe the problem is the ECu? Do the green relays by the ECU have to do with this? I have relays on there

[lilskyline240]

alright so figured out the CAS problem. We got the injectors to fire now. Now we have no spark.. Ive checked every pin on the Ignitor and we dont have any 12v power wires.. Im guessin i forgot to wire that in somewhere? cept i cant find any wires that i didnt wire up

any ideas

Do you have the green relays connected? or what's your white w/ purp stripe wire wired up to?

my white and purple is wired up to the White wire in the fuse box. i need a whole write up if any one is interested in helping me out. my RB wont crank at all after i wired it up.

Not sure but check the FAQ Section.Should be some write ups in there.
