To see if it's fluctuating while cranking at coil plug . Did u test injector pulse with a noid light
Normally the plug on the dizzy are always a bit dodgy on the rb30
oath, you can actually buy a wire and plug kit now(oviously for a while) from repco/bursons/pep's etc for that plug as they do cause a lot of issues
thats why it has been siliconed to fark haha havent touched the plug tho!

If injectors are going then it's not the CAS.
Something/somewhere between the ECU and coil is broken.
Put multimeter on frequency setting and probe the trigger wire to ignitor at the ignitor end. If you get a freq. on that while cranking, the wiring to the ignitor is good. If you get no pulse there then probe the same wire at ECU end. It's a borked ECU if you get no pulse there.
Probe the trigger wire between coil and ignitor after that and look again for frequency. Ignitor is fine if you have freq. there.
Have 12v at the coil?
Is the ignitor earthed out?
