To wire a kill switch to the fuel pump on a 1989 Crown Victoria, locate the fuel pump relay in the fuse box. You can interrupt the power supply by cutting the wire that connects the relay to the fuel pump and connecting the kill switch in series with that wire. When the switch is off, it will prevent power from reaching the fuel pump, effectively disabling it. Make sure to use appropriate connectors and ensure the kill switch is easily accessible for safety.

The Chevrolet Lumina fuel pump is powered by the electrical system. The fuel pump has a ground wire and a positive wire. The positive wire goes to the fuel pump relay switch.
A loose kill switch wire on your out board motor will cause the engine to lose power. As the kill switch loses contact the motor will begin to bog down or completely quit.

You can tell if your fuel pump shutoff switch is bad, if the fuel pump does not shut off when you flip the switch. You can also tell if the switch is bad by looking at the wire connections.
Just put a switch in the power wire going to the coil.
Isolate the wire going into kill switch [wrap some tape round it] so it cannot be earthed.
The fuel pump relay is a switch that let's a very small wire from a cars computer operate a component such as a fan or fuel pump that takes way more current than the small trigger wire could handle.
That is called an Inertia switch and Chevy did not use them on their trucks. You need to check the fuel pump relay and fuse first. Chevy also had a problem with the wiring connector on the top of the fuel tank were it plugs into the sending unit (wire would short out and kill the fuel pump) You could also just have a bad fuel pump too.
