it might be ignition switch also.
maybe ECU, or some broken wire/ground.
if you want you can manually bypass ASD relay, or any other relay in
that sense.

I think you need to take a look at the wiring for thi sproblem first.

Thanks, I was hoping to avoid messing with the ignition switch if possible.
I'll keep checking wires in the meantime.

ignition switch is kinda simple. you turn the key and check if you get
potential on the output wires. that's it. get a pin, and voltmeter.
turn the key on, check if you get power on the necessary cables.
that's much simpler then tracing soem random problems down the road.
