rebuilt my motor now it will not stay running. 90 k5

[80' 427]

Old fuel is old fuel. I still bet there maybe something else wrong. Race gas doesn't last a year either.

Ethonal first killed my fuel injectors on my 1990 Corvette ZR-1 that was no joke.

Had serious fuel related issues with my 82 ferrari had to rebuild that whole system.
