No Spark HR Swap
No Spark HR Swap
Maybe there's a guru on here who can help.
So I'm trying to get my 2k14 swap running. The signal for spark isn't being sent (hooked up a ground wire watched for spark on #6 plug and then I tried #2). Start Signal (continuity tested this one also) and signal from cams check out as confirmed from doing the voltage test on the fuel pump while cranking from EC-705. I can't *detect* a fuel smell from the cylinder after cranking either. The coils have power and ground. Engine and starter have plenty of ground I even sanded the mating surface shiny.
Only code is for the crank sensor p0335, tried a different ECU took them both apart the circuit boards look brand new. Manual trans car but I don't think it matters

EDIT: ignsw wire only had power in the on position and also needed it in the start position
The ckps code is gone and darren said my cam signals sound good, NDS reports good injector opening time (pulse width) and injectors have their 12v source but I rented a noid light kit and it is not lighting up to confirm the pulse signal from the ECM. No codes other than fuel temp sensor and cruise control. NDS2 confirms ign switch signal and start signal. I've tested all the signal wires to ECM for continuity. I've tested every other relevant wire cam sensors, crank sensor, injectors, ignition circuit, start signal, ignsw, ECM power circuit. I don't get it. Fuel pump gets signal to run from ECM while cranking, nds2 shows a Pulsewidth that isn't being sent and I have no spark
ive also tried a couple ECMs and no change
