To start this off, my truck has been in storage for roughly 5 years. Before storage, drained as much of the gas tank as possible & removed the battery.

Starting off replacing with a new battery. Go to fire it up, just one solid thump of the starter engaging. No clicking - just throne thump.

The starter on the truck was replaced with a NEW starter about 2 Months before storage. Take it off thinking it was bad. They tested it at the parts house and Caledonia it a good starter. Charged battery while messing with the started. Tried again -- still just the solid thump
