start then stall 2000 denali

[2door2wheel]

i have a 2000 yukon denali and i woke up to a truck that wont stay running. it cranks and starts but stalls less than a second later. it has oil pressure. and it has fuel spark and compression. ( it starts every time just wont stay running) not sure the problem> when i parked it it was fine and woke up to this. any ideas?

Did you end up throwing parts at it or just doing the 30min relean?

just did the relearn for now but im sure ill have to bypass it eventually. i didnt think of the security im used to the old vats system in my camaro on that car the security wont even let you crank the thing
