If the gas cap vent is stopped up, it will start to run into issues. Try loosening the cap and see what happens.

That’s a good thought but I’m saying the port at the intake manifold actually isn’t making any vacuum while cranking. I took the pump out of the equation and checked vacuum signal at the source.
