can i use a 12volt switch for a fuel kill??
yeah i read alot of the other threads... they keep sayinguse a switch that can handle a 20 amp and thats the minimum....i have no idea what that means.....but i bought a 12v switch from autozone...
I just wanna know if i could use the 12v switch from autozone for my fuel kill switch....!!
any help is appreciated

Yes you should be able to. Do you have a part # or picture of your switch? The package usually has a current (amps) rating on it.

it means that the switch has to be able to withstand 20amps of DC....
if it doesn't, the switch will overheat and melt.. either starting a fire, or just not work.
The switch normally says how many amps it can handle either on it, or on the packaging.

As mentioned we need to know what the amp "rating" of the switch is to know if it will work on the fuel pumps power lead
Or you can do it the proper way and install the switch on the ground lead to the PGM-FI Main Relay, [fuel pump relay] actually it is the ground for the coil on the injector relay, [both the fuel pump and injector relays are in the PGM-FI Main Relay] breaking the connection on the ground to the injector relays coil ground will shut down the injectors, fuel pump, one of the powers to the ECU/ECM and a few engine sensors.
The reason it is a better way to go is it is a ground you are switching, not 12V+, and it is low current, under 250MA, so even a very small 1A mini switch will work, a lot easier to hide then a 20A switch.

amen, because your car is going to be gone if a theif runs 12 volts to your fuel pump. This is the main reason why I won't do kill switches like this anymore. Thieves adapted to this real quick. And now everybody is roking it.
