Most common problems are an acid rotted vacuum line under the driver's side battery or a bad brake light switch.

The brake light switch is at the top of the brake pedal lever.
Sometimes you can tell if it's bad by engaging the cruise while lifting up the brake pedal with your foot. Must be going at least 35 mph.
New switch is $12 from Napa.

if the truck is 4wd and that doesnt work either then its the vacuum line on the drivers side under the hood, below the pump, that happened to me and the cruise wouldnt come on.
