I am working on a 86 f-350 that should have been junked 10 years ago, it is over 80% cobbled due to the lack of proper care. The issue that i am curently working with is that the vehicle will crank but will not try to start until you return the key to the run position.

sounds like you need a new ignition module for your key. Randy

Check your starter for excessive current draw.
