Where is fuel pump inertia switch??

[gcwh02]

I just bought a tubular front bumper and when hammering out the bumper shocks from the frame to remember to reset fuel pump inertia switch after hammering out the shocks to the frame.

In the trunk, mounted on the inner part of the tail light mounting panel on the drivers side.

in your trunk. When you pop your trunk look along to the left of the lock for your hatch or notch there should be a circle hole cut out in the plastic and you will see a little red button

how does taking off the bumper affect the fuel pump??

it shouldn't. it's probably just a warning just in case you trigger the inertia sensor somehow, and maybe it has happened before, where customers in the past haven't been able to figure out why their car wouldn't start...? just my guess.
