1973 duster 340 will not start- no start

ok after storing my 73 340 duster, since November, I am having a fire up issue. car was running great when put away in an unheated garage. full tank, stabil all that good stuff, battery was on a tender and the car cranks , with oil pressure, but refuse to fire. getting gas in carb. no spark. ok, I changed the ballast resistor. still nothing. where would you guys look at next, and what order??
orange box shot?
coil shot?
distributor cap cracked?
plug and coil wires are pretty new
bad ground on box? worked before
bad connections under dist. cap?
any other wires I should look at?
getting frustrated so whats #1 to look at and so on
thanks much for any kind of help:sad1:
