    Okay, with the jumper installed, go to the fuel pump and see off the white/purple wire has 12v.

    Will do. Sorry, what's the best way to get to the fuel pump? Not sure exactly where it is on our cars

    Remove spare tire, then remove the panel in the tire well.

    But before you do that. Check to see if the inertia Switch is tripped, red button popped up. It is mounted on the left side of the drivers footwell.

    Post a photo of it.

    It was pushed down. It slides up and down quite easily

    Okay, on to the fuel pump then. Post another photo when you get the acces panel removed. You should see a 2 wire connector. You can probe the white/purple at the connector for 12v. If you get power. Then do a continuity test of the other wire to Chassis ground. If you have continuity to ground. (Your pump is Dead)

    Now that may be something as I am currently pulling the interior out for upholstery. Does that ground for the fuel pump come inside the firewall or stay in the trunk bay??

    It is inside but should not be in an area you would disturb with carpet removal. The inertia switch breaks the Ground path if tripped. You still need to get to the fuel pump to check things out.
