Without the engine harness connected? I'm trying to get a new upgraded fuel pump installed before I drop in my motor however I don't recall if the fuel pump will run when you turn the key to on without the engine harness connected?

Most will prime without the engine connected. Some will pump without stopping. Make sure you have the manifold hose secured.
