Denali acts as if the battery is dead.

When you turn the key on, is there power in the vehicle? Headlights, horn, etc and just won't crank until you hit the key a few times? If that's the case, it sure sounds to me like a starter solenoid is going out.

Yep. This.

If it does it pretty much all the time, the next time you go to start it tap it with a hammer or something first. See if it doesn't start right away.

OR... ignition switch.

Corrosion at starter...

Corrosion at starter...

How do i figure out/fix this.

 

[cheebs]

Better yet I how i figure out which one it is? Starter, Ignition switch or starter solenoid? or just replace them all?

 

[jaywoo65]

It's most likely the starter solenoid. I don't know if you can change just the solenoid from the starter on these or if they are one unit with the starter itself. Try tapping it with a hammer first.


I would say it's not the ignition switch if your lights and radio dim when you hit the key to start it. That's current draw from the starter. If the ignition switch was flaky the lights and stuff wouldn't dim down.

Go to passenger side, look thru wheel well towards back, youll see a thick red wire there... eyeball that then go under and take a peek.... 2 bolts holding starter on easy peasy... but check wires there for corrosion, green, nasty battery term looking shit...

That is completely inaccurate in reference to the ignition switch.

Feel free to elaborate. Tell me how you will experience current draw from the starter if the ignition switch is faulty and the engine isn't cranking.
