Truck Dies Right After Jumpstart

[FlyMike]

I get back to my '19 1500 Limited after sitting for 3 days and it's dead, reaaalll dead. I hook up my jump starter Gooloo GT4000S, and it fires right up but then dies after a few seconds. Try again and it starts so I rev it a little, thinking I might need to get the alternator going a little more, still dies after a few seconds.
I'm taking a new battery with me when I go back Friday night to see if that fixes it. Had to replace the original a little over a year ago after having a similar issue.

Any ideas as to why it dies a few seconds after starting with the jump starter? Is the battery bad again? Maybe alternator too?

I think I have something that randomly stays on that kills my battery. I had to have the infotainment screen replaced about a year after purchasing since it was stuck in a boot loop and killed the battery. I'm thinking maybe something infotainment related or maybe air ride. I'm going to dig into that once I hopefully get it home.

I am on my 3rd battery, avarega life span has been 1.5 years. 1st one was cover under warranty, after the second one died I went with an agm. Hoping it will last longer. Had the exact same issue you described. New battery was the fix both times.
Dealer was not able to find any issues the 1st time around. Second time I just upgraded battery and didn't take it to the dealer

Most likely that stalling will go away if you can keep it running a little longer.

Modern vehicles have preprogrammed idle settings that slowly adjust to allow for altitude and how dirty the throttle body gets. You just erased that soft memory with the dead battery, so now it has to relearn. If you can keep it running by keeping your foot on the pedal, it will eventually learn again. Just keep it running, then let off to see if it will idle, and if it starts to stall, rev it up again. It can take a while.

The battery booster needs to be configured to act as a surrogate battery, as the original is completely flat. My NOCO booster requires a sequence of button pressing to place it in battery mode in order to keep everything powered after starting.

Did you check the bolts in the engine bay circuit breaker box, make sure they are all tight. Have you put a volt meter on it to check it's current voltage? Either way, after boosting and starting, shutting down shouldn't be the case even with a low battery.

If it dies immediately after jumping, the alternator is likely bad and not producing voltage. The alternator should produce enough voltage at idle to keep the vehicle running even if the battery is completely flat/all dead cells.
Check the alternators output voltage

All good ideas above. Seems like a common voltmeter would tell you what the alternator is producing, right at the battery terminals.

Quick update. I put in a new battery and I was able to start and drive home no issues. Battery maintained about 14.2/14.3 volts all the way home (40min drive) according to the dash readout. I'll update more when I get the chance to look into what caused the issue in the first place. Thanks for all the good responses.

Crazy how a battery/voltage level affects these newer vehicles so much. My “Flintstones” older vehicles from the past would just shrug it off, course almost no computers in most of those 70’s and 80’s ones.

2 weeks in and it's dead again. Didn't show any signs, I've been driving it every day. Time to dig into the electrical. Anyone have a recommendation for someone around the Marietta/ North Atlanta area.

That sucks, did you check the screws/cables in the engine bay circuit brake box? If one of those is loose, it could be the cause of this. Takes like 5 minutes, highly recommend that's your next step if you haven't done it already.

Unhooked the battery, checked the voltage and it's a good full battery. Hooked it back up and it started right up. Connections to the terminal were nice and tight, breaker box wires were tight, all breakers seated and not blown. I did find the main positive and negative wires off the battery were a little loose, barely finger tight, so I snugged them down. Hoping that's the issue.

Pay close attention to the negative cable connection at the fender stud also.
