03 Escalade ext cranks then dies

[Don Worrell]

I am working on this truck for my sister. when you turn on the key none of the gauges on the dash move, the door unlock/lock buttons don't work. it cranks then immediately dies. checked fuses none are out. She has regular keys but no key fob for it.

Thanks for any help
Don

I'm not a mechanic, but I always check for the 2 basics--Does it have spark?
Does it have fuel pressure when turning the key?
Have you checked those 2 things yet? Also--do you get the padlock icons on the cluster? If so you have a passkey issue.

It actually cranks but just dies right away. getting fire and fuel it seems. the only thing on the dash is the battery icon

auto door locks wont work, auto windows don't work, nothing on dash but battery icon, brake and seatbelt icons. Radio works and a/c system works fine (fan blows and can adjust system with controls)

If you turn the key to the start position and let go of the key so it returns to the run position, does it continue to crank for a few seconds?

Almost like it doesn't know it's been unlocked. Know anyone with a spare fob. Quick program worth a shot. Seen weirder things before.

Im having the same issue, did you figure it out?

I don't have enough information other than to make guesses. I'd check the positive lead coming off the alternator to the under hood fuse box. It may have been rusty, and work under the hood took it the rest of the way. I'd check all the grounds, too.

Could be the theftlock/passkey. Does the double lock icon light up in the dash? Any codes?

Year? Make? Model?

And the OP hasn't been on here since 2019; I wouldn't expect an answer from that section of the choir.
