wishiwasturbozx Posted November 23, 2013 Share Posted November 23, 2013 I have a project 81 280zx when key goes to on position pump makes noise as if it were on. But no suction dosent suck up fuel should it be wrote off as a bad pump or are there ways to test ? Or things to try ?? Quote Link to comment Share on other sites More sharing options...
NewZed Posted November 23, 2013 Share Posted November 23, 2013 (edited) Use ears, with method on EF-13 to run pump. Add fuel pressure measurement to quantify findings. You could also pull the line off of the filter outlet and see if anything comes out. At least you have power if the pump is what you're actually hearing.
