alvinheu Posted June 27, 2014 Share Posted June 27, 2014 hey guys this is my first post. anyways im in the process of getting my l28et swap to start going but notice that my fuel pump is not working. when my ignition comes on all i hear is a click from the fuel pump and thats about it. i mean its not even a loud click you wouldnt even hear it if not right under the pump. i tried to directing it straight to ground and power and it turned on for like 3sec then died off. after that it only clicks on direct power as well only. any help would really help thanks.

Domzs Posted June 27, 2014 Share Posted June 27, 2014 Sounds like a bad fuel pump . Try to tap it . Quote Link to comment Share on other sites More sharing options...

NewZed Posted June 27, 2014 Share Posted June 27, 2014 The fuel pump is not supposed to stay on unless the engine is running. On early cars nothing happens until you hit Start. Later cars had a priming function controlled by relays and/or the ECU. You need to know what is controlling your fuel pump power. Quote Link to comment Share on other sites More sharing options...
alvinheu Posted June 27, 2014 Author Share Posted June 27, 2014 i have it hooked up the existing 260z fuel pump relay where its a switched 12v and it only gives a light click so its not even pulling any fuel from the fuelcell to the lines to the rail.
