Occasionally starts but will immediately shut off . And will not run until you leave it alone for ten minutes. (I'm guessing the body control module resets) then it starts up and runs fine. Weather temp changes I noticed is a factor . Also if it doesn't start just leave the radio on and don't open the drivers door . Pull the key out of the ignition
And then wait for the radio to automatically time out/turn off. Then it will start every time.
I have a 2006 envoy Denali keeps cranking no start, all the lights and power go out, I wait about 5 10 minutes then it starts fine. It starting to do this every time I go to start car.
my security system has been blinking since I bought the truck when I purchase the truck it was at 150,000 miles now and it is at 202,000 miles when the security system blinks I will have to wait 5 or 10 minutes for the truck to start but now the security system light is on permanent and the truck won't start completely. It turns over fires up once and shuts right back off.
