Hey guys.
73 1.7 D-Jet. 3 port Bosch fuel pump (now located under the fuel tank) runs constantly and is a bit loud. I read that it is supposed to run for 1-1.5 seconds and stop with key on engine off. Checked wiring and found it is wired directly to Fuse #8 on the fuse panel. Where should it be wired? Side note. Car sat for 5 years before i rescued it and the fuel pump had power but didn't run until i whacked it a few times. Thanks in advance, You guys are awesome and your expertise is much appreciated. |

If you look under the car right behind the passenger seat, there is usually a white plug hainging there, or mabey ziptied up in the bay. If the PO rewired it direct to the fuse box, I would suspect there is an aftermarket switch in the cabin eithere on the dash or center console to kill it (IMG:style_emoticons/default/confused24.gif) |

No aftermarket switch but i could add one. Should it be wired to the plug behind the pass seat in your opinion?

(IMG:style_emoticons/default/biggrin.gif) IMHO, your current setup is dangerous! You should use the stock wiring and plug to run your fuel-pump. That way, it will be controlled by the FI brain. Simply run two wires from your current pump location through the center tunnel to the lower engine bay, add two male spade connectors to the wire ends and plug them into the stock plug.
