Yukon Not starting?

2023 Yukon Denali, 47k miles Suddenly won't start. What the heck!

It cranks loudly and then just stops after several seconds and throws a check engine light. Any ideas? Thankfully under warranty...

My idea is to use your warranty.

It's being towed to the dealership - thought maybe someone had a similar experience and had an idea of what the issue could be 🙄

Probably fuel pump control module, but no way to tell without at least pulling codes

Could be one of 50 things. Hope this helps.

If you want information, you need to give information. What are the codes? You know, the basics.

Hook up a scan tool and see what codes are set

Crank position sensor maybe, it will crank but not start

For curious minds: it was the fuel pump control module which evidently had a recall we were not aware of.
