When the starter motor turns on and spins the gear, the engine roars to life. If any of these stop working, it means the starter won’t turn over in your GMC Sierra.

What happens when you turn the key on a GMC Sierra 1500?
But nothing happens when the key is turned to start. No click, no groan, no hiss, no clatter. The first time, about 10 minutes later, the truck started. Next time it took about 30 minutes. Next time over an hour. That time I had it towed to the Chevy dealer and when they got to it the next morning, it started right up.
What should I do if my Sierra does not start?
Place the black lead of the multimeter on the negative battery terminal. If the battery reads less than 12 volts, charge it or replace it. If the battery reads higher than 12 volts, the battery is not the issue. If the Sierra does not start after replacing or charging the battery, move to the next step.
