Yukon will crank, briefly start then shut off...

[Mook]

Passlock problem? The security light only flashes if the door is open but w/ the door closed, doesnt come on. Doesnt flash when trying to crank.

Battery seems fine. I havent gotten under the car to listen for the fuel pump yet but I have a hard time believing it would up and shit out when it ran fine at like 10pm last night.

I initially tried starting the car today w/ the remote start and the car tried to start a few times before i noticed it wasnt working.

I will say, the security light came on the other day on the way to work but turned off once i got to work and hasnt come on since.

I know nothing about these trucks other than theyre comfortable...are there and quirks that i can easily check?

Factory remote start? or aftermarket?

Aftermarket...

I said VATS first, but now I'm saying remote start problem. It's been flaky lately too, yes?

It'd been working great actually.

Definitely has something to do with the remote start. Loose wires, bad bypass, etc.

remote start for sure
