I just swapped a 5.3 into my 94 obs and it won't run. it fires up then shuts off right away. i don't have any o2 sensors hooked up yet, I'm not sure if that could be an issue. Does anyone have any clue what it might be? or what I should look at.
help! 5.3 swap not running

it sounds like the VATS are not disabled.

VATS is still enabled in the PCM. You have to get someone to turn it off.
