I see this is a pretty old thread, but had to spark it up again as I don't see the resolution. My aux pump is doing this occasionally. Clicks away and fuel psi is 0. Doesn't happen very often...but the last time was recently.
Glad I read the thread as the plane won't be flying until it's fixed.
If anyone has any other advice than what's above or know the resolution this specific problem please let me know.
