okay, so i just swapped an rb20det into my s13 and i have no spark, i have constant power to my coil, i have continuity from my ecu to my ignitor, BUT i olny recive 1 volt to my ignitor, and i cant figure out why? and all of my grounds are hooked up, i even made a couple extra engine grounds, everything is hooked up and my cas is making the injectors tick when i spin it manually. if anyone has any ideas please let me know!! thank you

Is there power from the 2 green relays? one is for fuel and the other for ignition. 2 green relays near the ecu.

yes i know i have power getting to my coil but there is no signal pulsing it, i also only have 1 volt getting to my ignitor? and dont know why, there is no resistance in the wires from the ecu to the ignitor also.

Your ecu might be bad, so open both side cover and check to make sure no resisitors are burnt or trace damage. Good luck.

solved the problem, my #1 coil ground was broken when i pulled back some tape, i got it running, took it out, and melted a coil pack! fml, so now i have to find a new one, do an water pump gasket and exhaust manifold gasket, does anyone know where to get coilpacks, or have some?
