Hello all i have a frshly built sr20det i dropped into a 93 240sx. I cannot get the injectors to fire. I have sent my ecu off to Martin at RS-Enthalpy and it test fine. I have a brand new wiring harness from yury at wiring specialties and test continuity between all ecu grounds, injector grounds, and etc. Also have jumped 12v power wire into the injectors power feed to rule that out. i have talked to Martin and Yury multiple times and they are baffled just like me. I have 2 CAS and neither one will fire the injectors when turned by hand. I have spark at coils and the fuel pump primes. But when i turn the CAS by hand i hear no clicking at injectors and the noid light doesn't light up.( i did test my noid light on my g35 and it works just fine) Is there a chance that both CAS are bad? Both CAS were used and have no proof of them working before purchasing. I bought a brand new CAS last week it should arrive afternoon today or tomorrow. Any help would be sweet

Make sure the cold start is wired (your ignition sends powerd to ecu only when cranking) the wire comes from the plug under the dash I had similar problem when cranking the motor..................my motor wouldnt start and i used the noid light it would berly light up seemed like the injectors wernt getting enough power when cranking as soon as i hooked up the cold start it lit up the noid light really bright and started every time .........not sure if this will help but worth a try

Check the brown and or grey plugs by the passengers front fender. I've seen corroded wires break after a few years of normal operation. This is were the injectors get their power, so it's the first place I'd look. Good luck!
