Posted August 18, 200222 yr comment_13339 HELP….. I was over hauling the fuel system of my 73 Z to clean out all the metal lines, replace all the rubber hoses and change all the gas filters. This Z has been sitting in a garage for the 12 years and the tank was dry. . I pulled the electric fuel pump out and changed the filter and I bench tested the unit. The pump seams to be working fine, it pumped a good amount at a good pressure. I re-installed it and was trying to get it to pump enough fuel from the tank to fill the fuel system. I tried this by turning the keys to ACC and even tried to crank the engine but the electric pump would not pump. No I have not checked the power connections to the pump with a meter my kids have hidden it from me. The Haynes book I have is useless for trouble shooting this problem and I have no other sources of info.1. Which fuse is the correct fuse to check in the fuse panel? 2. Does the Electric pump come on when the ignition key is turned ACC? 3. Does anyone know if there are control relays some where else that I need to check? If so could you share the locations with me?4. Any other advice for this?Thanks in advanceAlordzot Link to comment https://www.classiczcars.com/forums/topic/2711-help-73-z-electric-fuel-pump-not-pumping/ Share on other sites More sharing options...

I traced the power from the ignation to the the inline fuse (black and white to green wire) but no power on the green wire to the electric fuel pump. I still could not find any relays on the green wire, are there any and where are they located.
