1997 murcury grand marque fuel pump

What is the easiest way to change out the fuel pump? I was told that I could cut a hole in the trunk to get to it. If I could where would I cut the hole and how big should it be?

Cut a hole in your trunk? YIKES!

Dropping a fuel tank is not that hard. It's held on by just 2-3 straps.

Get a syphining hose at a auto store, drain the tank (if you want)

Place floor jack with a small block of wood on it, and place it under tank.

With straps removed, carefully, and slowly lower tank enough to make sure the fuel lines will not get damaged.


I would not however, cut a hole in your trunk. Some vehicle, like mine, require you to just pull out the back seat and remove a small access door to gain space to the fuel pump. Check your trunk or a similiar door.


Here's the actual how-to procedure:

It's not easier to cut a hole in the trunk by any means

Like Hot mentions, you may have an access hole you can look for
-which I would look for first, but-
I believe you have to drop the tank on the Marquis

I haven't looked at the AZ instructions, but usually the A/Z ones are as good as any aftermarket manual

I would drain as much fuel as possible out
Use the jack/woodblock to support it (as all the fuel won't come out, it could be heavy) during removal
And def. remove it all the way after "dropping" it
Don't try and 1/2 drop it to save effort
It just adds effort to try and work under there with it 1/2 hanging off

And just a wild idea here, but if you are changing it because the pump isn't running, have you checked the inertia switch to make sure it isn't tripped?

The Ford/Merc Inertia Switch
If it's tripped by an accident (or speed bump or spirited trunk loading), the pump is disabled until the switch is reset

The cover in the trunk plastic "lining" will be marked and can be removed to access the switch
It usually is a button that must be reset by pressing down
