Hi Community,

I have a 91 Nissan 300zx NA that runs pretty rough at idle and can't climb uphills. It appears my fuel pump is going bad as it whines pretty loud when I start her up. I am replacing it with a Walboro 255 fuel pump. Before I replace it, I would like to see the before and after fuel readings. I have the paid conzult software (and cable) and am having difficulty seeing where the best place to look is. Anyone have any ideas?

Thanks in advance!
