Hi everyone. My name is Halo. I recently purchased a 2011 GMC Yukon Denali from auction. It was running fine until a couple of days ago I noticed it was taking a little longer to crank the engine before it would start. Then, yesterday at the gas station I parked at the pump and went inside to pay for gas, pumped the gas and when I tried to start it, it just clicked and wouldn't start. I tested the battery and it's fine. I am going to replace all the fuses and relays tomorrow, but I feel like it's probably the starter. Does anyone have any advice for replacing the starter?
2011 Yukon Denali not starting.

Welcome to the Forum from NH.
Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.
I hope that you will become a participating member in the Forum's discussions.
Pics of the truck, please.
You are already receiving sage advice from the knowledgeable folks on this Forum.
A quick starter test is to have somebody attempt to start the truck, and when you hear the click, smack the starter with a hammer to give it a slight mechanical shock. If it fires up, then it is most likely the starter or its attached (not-replaceable) relay.
"I tested the battery and it's fine." - The only true way to test a battery is to pull it out of the truck, take it to an auto parts/battery store with a bench load tester, and get it load tested. Have you done that? If not, do it, before firing the parts cannon with its associated extra costs.
If the battery load tests as good, then thoroughly check the battery cables to the main fuse, to ground, and to the starter. These cables typically rot from the inside out, so a continuity test should be performed on each cable to ensure that their resistance is very low.
If the main cables check out OK, then check all grounds in the engine bay, including the motor to firewall ground, to ensure that they are clean and tight.
If engine bay grounds are good, then check the ground on the truck's frame, approximately below the driver's feet.

For electrical mysteries I recommend seeing my post on the engine area fuse box. It gets corroded and relays randomly don't work, affecting starting, lights, etc. Mine is 2011 Yukon Denali. Folks mentioned cables, grounds, etc; didn't find that to be the problem. Tho it never hurts to check that stuff.
You can take it out and apart, clean it in an afternoon.
To check, have someone try starting or whatever while wiggling those big cable bundles.

Shut down /electrical gremlins update
I posted about a mysterious full power off. Also had a few gremlins; one high beam didn't work; left turn signal intermittent. Replaced the switch and checked/cleaned ground and power cables. Lights were still weird. I could wiggle the wire bundle from front bumper area and get the hi-beams...

Had a similar issue when I first got my Denali. It would drive fine and then all of a sudden it would not start and just give me a click. If I wiggled the main ground cable it would temporarily fix the issue and get me going. Ended up replacing the main ground cable and have not had that issue for almost 3 years now. Here is a link to the one I got.
Do a voltage drop test. There are some good You Tube videos on how to do it.

Had that happen to me was the cable coming loose to the starter. Cables first!

Hey OP, any resolution to this?
The OP hasn't been on here since the end of November last year.

Thanks I saw that. Not my first time on a forum. Some people move on but still get email notifications - that was my hope.
some do not unless you tag them @HaloDark if they neglected to subscribe to there own thread
