Since it was running before the new points and condenser, that would be the first place to look.
The new points, and especially condensers are notorious for being bad new out of the box.
Double check the installation on the points, the wire connections, the condenser base must be tight to ground. Assuming this is battery ignition, a test light connected from the point side of the coil to ground should come on when the points are open, off when they close. It should flash as the engine is being cranked. If no light, there is no power to the coil or the points are closed or shorted to ground. If it stays on, the points are not making contact or there is a wire connection problem from the coil to the points.
Also check the firing order of the wires, check the cap and rotor carefully against the original. Another common problem, wrong out of the box.
Were the plugs changed? If not, do so just to say you did. They can look good and cause strange problems. BTDT
A compression test would be the next test. Just don't get too many irons in the fire. Do too many things and the problems can be multiplied and the solution may never be known.
