Morphology

fire + up

The sense 'to start or switch on' is motivated by the metaphor of igniting or activating (fire) combined with an upward/completive particle (up), so a learner who knows 'fire' in the senses 'ignite' or 'excite' and 'up' as increase/activate can plausibly infer the meaning. However the mapping is somewhat metaphorical and not strictly compositional—learners who only know 'fire' as 'to excite' or only as 'to shoot' may not predict the machine-start sense—so it is partially transparent but not fully predictable.

Etymology

Fire up comes from starting engines and machines: you give a spark so the engine fires and the machine begins to work. That's why fire up means 'to start' a device, computer, or program.
