Help no spark, sr20

[mastashake]

Hi guys I have an S14 SR20 in a 240 and I'm getting no spark. The car had been running previously for 2 years with this swap, but I tried to start it one day and it wouldn't fire up. I've checked everything and my only problem is I'm not getting any spark(all 4 coils). Mostly bolt on mods, and piggyback ecu.

I've tried swapping coil packs, coil pack harness, ECU, and the ignitor. I've also checked all of the related wires and I do have 12v at each coil pack, ignitor, and the ECU. Signal wires are also getting power when I crank, I also have the right ohms(resistance) to all related grounds. ECU fault code reads 55(ok/other malfunction).

Is there anything else I should try?

you didnt mention fuel. I would say check the CAS. Plug in an extra CAS you have laying around (all sr20 owners should have a spare CAS) and turn it with the ignition on to see if the fuel injectors click. Also you can check if there is spark, pull out a plug on a coilpack and watch if it fires when you spin the CAS.

Fuel system is working fine, thanks I'll try and swap the cas and see if that's it.
