Have you tried disconnecting the battery. Maybe it will reboot. Sent from my SM-N975U using Tapatalk

If it's running good maybe just try clearing the codes to see if they come back. Sent from my SM-N975U using Tapatalk

I would start by going to a local parts store like Auto Zone where they do free testing and have them test your battery and check for any codes.

Yes. That is the headlight indicator. Sent from my SM-N975U using Tapatalk

There's some good videos on YouTube on changing the fuel pumps on our trucks. Sent from my SM-N975U using Tapatalk

Remote start will not work if you have a CEL on. Sent from my SM-N975U using Tapatalk

Maybe the new battery is faulty. When I bought my 2014 Silverado the morning after I brought it home it wouldn't start. While on the line with On Star setting up a tow I tried it and it started. Went to work came out no start. Got a jump went to dealer they tested the battery and it was bad. Sent from my SM-N975U using Tapatalk

The spare does not have a Tpms sensor. Sent from my SM-N975U using Tapatalk Sorry re read your post. The sensor must have got damaged when they repaired your tire.

Get a tune.

Try disconnecting the battery for a while. It may reset.

I just started having this same issue on my 2018 5.3. I put in some fuel line cleaner, no help. Yesterday filled up with some 89 octane to see if that helps. Gonna give it some time to run thru. Hoping it's not transmission related. Seems to have some similarities to the torque converter issues I've read about. I've checked to see if there are any codes being thrown but not seeing anything. Just hate to take it in and have them tell me they couldn't replicate the issue. Post up if you get this sorted out.
