1972 dart 318 problem starting
Now the car will crank in park and will not start most of the time if it was not used earlier in the day, but the car will start most of the time in neutral. After driving the car and shutting it off and trying to restart the car it for the most part will restart in park
I think rammer jammer is on the right track.
What you are describing sounds like the typical carbonated car being harder to start than an EFI we have all gotten used to.
Drive car today or yesterday, 1 to 2 pumps of the pedal and it will fire in a second or two.
Let it sit for a week and it takes more pumps and more cranking time.
My guess is you are cranking in park and almost getting to the point it will fire.
You give up and put it in neutral and try again and it fired.
That leads you to believe it will fire in neutral but not park most of the time.
My 67 dart 2bbl 273.
If I started it yesterday, 2 pumps and a few seconds of cranking and it fired right up
If I started it last week, 4 pumps, a few seconds of cranking, stop. A few more seconds of cranking and it will typically fire.
If not, give it part throttle and a few more seconds of cranking and it will fire.
I would check that the accelerator pump is actually shooting fuel into the carb. Next time you go to start car after a week BEFORE you do any cranking.
Pop the hood, remove the air cleaner, open the choke and look down the carb while moving the accelerator linkage to full throttle you should see a full stream of fuel shoot in.
As for the neutral safety switch..
All it does (unless modified or damaged) is make a path to ground for the starter relay in neutral or park.
Now MAYBE there is a wire dangeling near the shifter linkage and in park it is causing issues, and I neutral it is not.
Worth looking at.
