I have a Holley Blue hooked up to the stock wiring. It's been this way for the past 5 years working. When I crank the key usually then you can hear the pump humm. The fuse is good, and I jumped 12v directly to the pump and she works fine. Any ideas...?

 

See if your getting that same 12v on the lead going to the pump.Then check to make
sure its grounded good still.

Might be a break going back to the pump. It has to travel down the side of the interior
under the carpet and can get damaged over time.

 

I don't have my multi-meter w me today. Isn't there a relay under the dash / steering wheel area that can be jumped out to make it constant...? I remember but can't find it using the search...

 

I figured it out... It was a bad connection at the pump. I used M-F connectors for a quick disconnect should I ever have to swap out pumps. If anyone knows how to find the thread that shows how to constantly wire / jump past the relay I'd still like to know, unless I find it first. Thanks.
