    Only 1 Coil no spark help please

    I have tested the wiring a few ways started with a coil and plug and changed out each set of coil wires and got spark arc when cranking on all but wires for cylinder 1.

    From there I tested the wires...

    power on I get 12v and ground with the multimieter and ground is good

    I checked the signal wire from harness to pin 50 and have continuity.

    what can I test next? I cant find anything that says what the signal wire should be tested at using multimeter.

    Also with wiring testing good is it possible the dme is bad and not sending a proper signal?

    Need to get this sorted so I can swap motors and nkt be chasing an already existing demon
