The Tahoe won't start this cold morning..... just "click" which makes me think I need a new starter. It did this about a year ago (also cold) in my workplace parking lot and luckily came to life after a few attempts. No issues since.

Jump starting did nothing. Full power everywhere else.... pretty fresh battery. Some electrical stuff was bugging out, and I got a few warning messages (service traction control, service air bag).

I have a PO650 code but that's been on for a while and seems unrelated.

Also important to note that something weird has been going on for a few weeks when I go to start. If I immediately try to start it in the morning after it's been sitting a while, it'll sit there and turn over for 3-4 seconds until starting. If I leave the key in the on position for a few seconds first, it starts right up.... which seems like maybe the fuel pump, which would be unrelated to this issue of not starting. If it's not the fuel pump, then it might have something to do with it...

Any thoughts?

I'm going to go ahead and replace the starter first since I'm sure it's about due for one, even if that's not the issue.

Yea. I pulled the front off and it made it pretty simple. I didn't have an issue with space. Compared to the T/A this was a dream.
Amazon. Decent quality for way less than the auto stores.

They weren’t some of those selling on EBay for 1/4 the normal going price were they? I have recently saw some ACDelco iridium plugs on there selling for unbelievably cheap prices and Im pretty sure they’re knockoffs.

No, I bought them from my local Autozone. I don't trust buying spark-plugs from anyone but an auto parts vendor

Then tell us how genuine ACDelco plugs “went to shit” in a few months. This is actually the first time I’ve heard of this happening. As in ever. Fill in the details, as in exactly what went to shit means and any other abnormal conditions, because they’re without a doubt the best plugs made for our vehicles. Nearly everyone here runs them, most for years on the same set, without a problem. Did you attempt to gap them by any chance?
