Re: Question about my fuel pump

You need to do or have a leak down & pressure check. Your fuel pressure should be 60psi it should hold 55 for several minutes. If it drops too quickly you most likely have a fuel leak & that effects mileage.
I just noticed if you check the post on 2001 fuel problem on of the guys gives you a step by step guide for checking pump & leaks.
