225 six wont start

I would check for spark first. If you have spark then that would rule out the distributor and resistor. If no spark then check the distributor, then resistor. If you have spark and still no fire, I would check fuel. If fuel and no start or at least try to start, try the inital timing. Set your marks on DTC and pull the distro cap off, look at the rotor and see if its pointing to the right wire for #1 on the cap.
This should get a little closer to the issue of no starting.
