Injectors and coils not firing

[jonvr4]

So I started doing an SR20DET swap into my S13, and have been having issues getting it running. I get no spark, and the injectors don't pulse either. I have traced wiring over and over again, and put a new Z32 ignitor in as well. I have checked grounds, and followed the heavy throttle wiring instructions. I have power to the coils, and injectors, but they don't fire when I crank.

I pulled the CAS to see if that is the problem. When I rotate by hand nothing fires. I also checked the ECU and it's giving the normal opperating code.

I am starting to think it's the CAS, but haven't checked to see if the Ohms change when I rotate. Anyone have any ideas?

Turn the ignition to on and make sure you have power going to the injectors. The power supply is hot when the ignition is on, and the ECU grounds them out to fire.

you seem to be heading in the right direction narrowing the possibility down to the CAS, but I wouldn't rule out a bad ECU either. However, given that both your injectors, nor your coils are firing, the CAS sounds like a possible culprit. If you have an extra one or have a buddy that likes you a lot, you can try swapping a known good one in.

Retitled the thread and moved it to RWD SR

Thanks for the suggestion, I'll be looking into both tonight. Sorry for putting the thread in the wrong section!
