The red/green wire to the coil resistor only has power in the ON position. It does not have power when you turn the key to START. If there's no power in the ON position then your ignition switch is defective. You can move it to the ACC terminal on the back of the ignition switch and try it there. However your car should fire without power to the red/green wire. In START mode it gets power directly from the solenoid. If the car is cranking then you have power at the solenoid. Check the brown wire on the solenoid for 12V. That goes to your coil.
