How Test if the Ford Inertia Switch is Causing Fuel issues | Checking Voltage Drop

[@ruabadkitty]

Thank you very much. I am traveling in my van and I believe my fuel pump is going out so I am trying to learn about it myself so I don't get ripped off. Being over 60 and a female I am easy prey for a shady mechanic on the road.

No problem. Most likely a fuel pump or strainer/filter they are common to go bad on ford trucks. You want to replace the entire fuel pump unit with a quality part like a delphi. And its best to drain and drop the entire tank out and have it inspected and properly cleaned with a delphi cleaning kit. Delphi actually offers a lifetime warranty on their pump units if tank is cleaned properly. The people cutting holes in the floor and just replacing the pump are not saving much time and a dirty tank will make a new pump fail again prematurely. Best to do the job right

Out of my 30 + yrs and never had one of these go bad they ether work or they dont most likely its a bad pump

Yeah they probably dont go bad often, nothing wrong with my van after a new fuel pump and filter, just showing people how to check voltage drop and getting a baseline for what a good one looks like
