Sr20 another no spark...

[oXeNo]

I got my harness in today for my sr20, I got everything wired up and grounded properly, go to start it and I got no spark. The fuel pump primes and injectors fire, I got a new ignitor to go with it as well. I got power to all the coilpacks and ignitor as well. I'm thinking it might be my ecu but I'm not sure what do you guys think?

Could be ECU smell it...yes smell it...Does it smell like fried circuit board?

Open it and check but be careful not to mess it up. Look for burn marks on the board to see if it's dead - ignition drivers could be fried. Also check for corrosion on the actual pins that go into the ECU plug for ignition output.

Check your coil pack harness. Check the ground for it on the back of the engine and head. Try another ignitor chip if you can just to double check

What about your CAS? If your CAS is fried or your CAS plug or harness is screwed up this will also cause no spark condition.

Hope this helps.

Thank you for the help, I just sent my ecu back to jdmenginedepot and they are going to send me another one. But yeah I don't know if the cas is good I bought it from someone that told me it was fine and worked. When I turn the cas I can here the fuel pump prime and the injectors click. But I still am not sure if it could be my cas. I have checked all the ignition wires and everything checks out perfect according to the fsm. The coil pack harness is grounded properly, and is getting 12v to all the coils and everything.

Ok so I got my ecu finally, it's good the fuel pump primes and everything correctly, but still no spark. The coils are all getting 12v and have a good ground. I re checked all the wiring and checked continuity. It all checked out. I am so lost as to why I still have no spark, I have 2 ignitors and both are good I have checked them as well. Could it be my cam angle sensor?
