I think you found your problem ......It sounds like your ignition switch has a problem.
I have 2 cars that don't have chokes one is a 512 with a Holley 950 HP with no choke horn and electric fuel pump. The other is a 440 with a Holley 800 DP it has a choke and choke horn but it's not hooked up and a mechanical fuel pump. Both start about the same way after sitting for months. On the electric fuel pump car I turn the key on let the carb fill up then pump the thorttle 5 times crank with my foot off the throttle let it start and die pump the throttle 5 more times and start it nurse it along by tapping the throttle just enough to keep it running for about 30 seconds then rev it up to about 2,000 rpm in little burps a few times and it will idle. I do the same thing with the mechanical fuel pump car but before I do anything I crank the engine for a couple seconds to get fuel in the carb.

While I will agree it sounds like his ignition switch is faulty, I'm still inclined to point the majority of the poor start up blame at his lack of a choke and fuel evaporation. Keep in mind that choke realated issues are going to be more pronounced in cooler climates (you being in Arizona likely helps you a ton).

There is your problem. The wiring to the ballast resistor has 2 circuits. The blue wire which has 12 volts with the key in the run position,but in the crank position it has 0 volts. The brown wire has 12 volts in the crank position only. If you lose the brown wire feed you will have no voltage to the coil during cranking.

oh i don't know. i know my car starts a lot like his car ( see my about post) i'm in jersey and it gets down in the 20's and 30's most winters and my chokeless dart doesn't go fouling plugs even on the coldest of days. the OP has an issue somewhere and i doubt its all the lack of a choke. yes it may be harder to start then a car with a choke or a car with a fat carb but it shouldn't be fouling plugs like he says its doing. probably has multiple issues thats causing it. and we probably aren't getting all the details either..

Caught the part about the car firing while the key is released - verify power to the ignition while cranking and when key is released.
Had a B- Body that would only fire when key was released - found one of the wire terminals had backed out slightly in the connector body at the bulkhead connection
Dad was a journeyman electrician/ 30 yr CRC repairman. He found it in a few minutes. It's called "apparent power" - terminal is touching enough to show voltage on a meter but connection won't pass current.
Was pulling my hair out for days. I was 17 (24 years ago) but I won't forget the lesson - Thanks Dad.

Be sure to check the distributor connector. i had one slightly loose yesterday and it kept my 85 from starting even hot wired (I have a bad switch). Did the same, would kickback on turning the key off or disconnecting the coil power wire. also check the pickup coil.

BB Mopars are tough to start after a couple days especially with todays fuel. You should really have a choke, makes life a lot easier.It's really tough to hit the sweet spot before flooding. As was said, verify power to the coil in start mode. You may want to also verify spark voltage with an engine analyzer, you may have a weak coil, a bad connection or other bad ignition parts.
I have a 440 in a 69 GTX with stock AVS carb and stock choke. The guy that restored my AVS gave me this procdure, works every time. If it's set more than 2 or 3 days; Without pressing gas pedal run starter for 10-15 seconds. Pump gas pedal 2-3 times, (this sets choke and gives accelerator pump a couple shots), it starts right up. Of course if you run it daily, before the gas evaporates, just set the choke with one push to the floor and it starts instantly.

Thats how this one does if its not 'too' flooded yet, just turn the key from run to off between cranking and it will kickback and apparently that burns enough off the plugs that it will start. Its too flooded this time and wont start, last time it did this i had to change the plugs.

losing 5 volts just in the wiring is a problem.
if you jumper over the ballast, you should have full battery voltage.
sounds like you've got bad wires with really high resistance, bad terminals on the wires, or both.
Check out all of your wires before something catches fire. pay close attention to any that pass through the bulkhead connector on the firewall.

Try this as a short term troubleshoot, unhook the coil from the stock positive feed, and hook it to a fresh clean wire thats run straight to the battery.
you'll have to hook it up when you go to start, and unhook it when you're done driving, but it will allow you to see what happens when you get full voltage to the coil.
I bet it fires up like you put nitro in it!

I had a Fuel pump issue with my Carter pump, if the car sat for longer than 2 weeks I would almost have to prime the system with fuel. Then I decited to try a Holley pump, That fixed it, Now the only time I have starting issues is if it sits for longer than 3 months, then it cranks for a few times, builds fuel PSI, and starts up. You may have a few different issues, Hard to tell without standing there and seeing for my self, but ya may have a bad switch, and a fuel pump thats gone south. Hope ya get it figured out. Oh and I run a holley 750 with out a choke and a proform main body, so its basically a race carb, and I dont have a lot of issues with it when cold.
