this is why a Remote Starter Switch is an absolutely essential trouble
shooting tool.
By using one  you separate the 'ignition on' function from the 'crank the
starter function' ............
You should also just check for power in the right place, like at the coil
with the key in the on position.
- though that doesn't  fit with the symptom of stumbling or hesitating.
Besides idle switch adjustment, AFM also popped into my mind.
