Every now and then the remote start in my 2019 Yukon will not work. I do NOT have any check engine light on my dash at any other time. I am aware that a check engine light will disable the remote start until cleared, but that isn't what is happening here.
Thus far I have only experienced this issue when remote starting in my garage after the vehicle has not been driven all evening and night. I do not lock my Yukon at night, if that matters. I'll press lock and then immediately hold the remote start button, and occasionally, it will not start. If I look through the window, I'll see the check engine light illuminated on the dash. I can try to remote start again, and the same result will occur. However, if I unlock, open any door, close the door, lock, and remote start again, it will work perfectly and remote start just as it should. Every single time that the remote start fails, if I follow this sequence of operations, it will function perfectly.
Brainstorming, it is my thought that perhaps I am interrupting the fuel pump prime procedure. You are probably aware that if you haven't driven your truck in a number of hours, you will hear the fuel pump prime when you either lock, unlock, or open one of the doors of the truck. So, if sitting all night, pressing the lock button "wakes up" the truck and causes the fuel pump to prime. My only thought is perhaps I am pressing the remote start button and not allowing for a brief delay? At the same time I am wondering why it seems to only reset itself once I open and close a door.
This applies to all 2015-2020 full size SUVs, but will also apply to all 2014-2019 full size trucks, since just about all, if not all, of the electronics are identical.
