Do I need a fuel pump inertia switch?

If you have the fuel pump controlled through the VCM it will kill fuel if the engine dies. I am not aware of any GM cars with an inertia switch but Ford loves them. I have one on the Thunderbird only because it was already there, but none of my GM cars have one.

It's a safety item, if your car gets hit, the motor doesn't just die. They are super easy to wire in and about a gazillion of them in Taurus's waiting to go into a hot rod. You can even get them with a hot output when activated so you can put in an idiot light and tell if it got activated (might make troubleshooting easier).

I bought the Mustang inertia switch sold by Summit to mount it my conversion in the interest of safety. Impact or roll-over and it shuts down the fuel pump. And yes it has a normally open in the connector that you can run to an indicator in case it gets tripped.
