Power to my GMC Sierra 2008
I checked into a hotel and parked the truck. I
came back down from room and unlocked
the door with Key faub and got in and went
to start it but nothing. There is absolutely no
power to anything!! What would cause that??
Your situation is most often related to a dead battery; not enough juice to light the lights or to turn the starter motor. Jump start the car properly; leave donor hooked up long enough to charge your battery, at least ten minutes. If your car starts, fine. If it does not start, replace your battery. After either of these, go to an auto parts store and have any codes read. They may point you to the reason your battery died. Probably a bad alternator and I'm guessing you've had a battery light on your dashboard for a while.
