Car wont start unless door is open

Wow. Started reading this post.
OP stated this car had sat it a field for 20 years.
imagine every connection needs to be looked at!
anything diddled with has to be double looked at.
May I suggest using a test light, ( something that draws current) rather than a meter, to check for power on circuits.
Good luck

Good idea. I will buy a test light tomorrow. The previous owner had mentioned that he replaced the ignition swicth. Im not sure if he replaced it because even before that the car still wasnt starting correctly, or he put in a faulty one.

The current state of the car is quite interesting. When i took out the extra dist. jumper, the car started every time regardless of if the door switch was grounded. However, it would die instantly and isnt getting any spark when key is in run position.

So then i hotwired the coil positive to the battery and it stays running after starting.

When i put the jumper wire back in, the door buzzer has to be grounded for the car start. But, it stays running unlike when the extra dist. jump wire is out.

Sorry if this response is confusing, but its accurate to whats happening.
