If the cruise control will not engage, there might be a problem with the Electronic Fuel Injector or the MAP Sensor. There might also be a problem with the Oxygen Sensor. Some autos have more than one oxygen sensor.

There are a number of reasons why your cruise wont work on a 1999 Ford Pu. Your wiring could be fried.
Usually the horn and cruise control go together because of the clock spring. It needs to be replaced and there is a recall for it.
Toyota previa starter motor wont engage
Replace the cruise control switch (the one with the orange light in it) The switch is a push on push off. If the little plastic gear inside the switch breaks off the switch will work like a door bell switch and will not latch on.
Vacumn modulator could be at fault. In older cars both the transmission and the cruise control rely on engine vacumn to know what the engine is doing, if the vacumn strength is not properly relayed to these components then odd behiavior will result because the tranny and cruise control don't know what the engine is doing.
