How do I install a fuel pump kill switch on my 1984 300zx?

Question

I've been surfing the internet and I can't find any wirte up.
which wire to cut?

Answer 1

First find your fuel pump, there will be one or two wires going to it - hopefully two, the 2nd is to provide a better ground, and will most likely tie into the chassis close to the fuel tank. The other wire is the hot one, you should be able trace that back to your ignition switch. Put the kill switch in the circuit close to the ignition switch, mounting it in a convienent location. You may also want to consider installing a roll over kill switch at the same (if there is not one already installed) time - which if you roll the car, will shut off the fuel pump. These have to be manually reset.

Answer 2

Way to go Nigel... I find the fuel pump relay and the ecm grounding circuit cut that wire and install a switch. A cool switch is a window alarm magnetic reed switch place a magnet lets say in the consol closes the hidden reed switch under the plastic and car starts pull the magnet throw it in the glove box car does not start the magnet does not need to touch just be close to close the switch. Ash tray with the switch on the bottom drop in the magnet car starts. locations are endless. I think your fuel pump relay is up above the cars computer right hand kick panel.
