Wire grounding out?
 

97 4x4 4.3 automatic
-Battery was dead after not driving for 2 days; after it died again i replaced the battery with a new one since it was a few years old.
-Truck ran fine until I left it for a few days again. I turned the key and nothing happened, then I couldn't get the key out.
-Checked switch on side of shifter and it was fine, removed key by pushing manual release button.
-Then I jumped the truck and it started but the starter kept trying to engage even after removing the key.
-I was thinking it was the ignition switch but that shouldn't cause a power draw overnight that is draining my battery should it?
-Now I'm leaning towards a starter or remote start wire grounding out somewhere.
Anybody have any opinion/idea before I go out in the single digit weather and try to figure this out? Thanks

Might be a good idea to remove the remote start unit, and its wiring, and see if the problem still exists.

1997 uses a unique ignition switch. It is the only year it was used and it is known to have multiple "issues". This thread explains:
