Sounds like a bad starter. When you turn the key the starter drive is forced out into position to engage the flywheel teeth. Sometimes when a starter goes bad it's because the drive is no longer being forced out. It still spins when you turn the key but doesn't engage the flywheel. The spinning starter is the humming that you're hearing. HTH. -Jim

When a vehicle sits and is not started for a while the battery gets weak because the alternator isn't run to keep it charged.. the battery uses all the energy it has when you first try it and then goes dead. Have the battery recharged.
