Hey, I have a 95 Mustang GT with a Crimestopper cs-2016fm alarm/remote start. I also have a hidden fuel cut off switch and I was wondering if it would be possible for me to hook up the alarm system to that, so when it is armed there is no power going to the fuel pump. This is probably basic stuff but I am a novice with this stuff. I did install my alarm so I have a little bit of knowledge.

Thanks
Joe

Is this not possible? Why is it a bad reason?

just place a relay next to your switch. wire the relay to the starter disable wire on the alarm. then you have a manual switch also for extra safty.    and there is nothing wrong with cutting the power to the fuel pump. i have seen it done many times

Why not just have a starter kill relay.

If a starter kill fails, customer will be stranded at the mall or at home. Sucks, but not the end of the world.

If a fuel kill fails, customer might be stranded on the roadside. They'll be quite angry. Even worse, if they're a lousy driver, they'll allow the car to come to a stop in the roadway, have an collision, and the shop could be liable.

If you do a fuel kill, be very, VERY careful about the quality of your work, and make a way to jumper the system back to normal (without tools) should something fail.

I argee with chris. I dont recommend doing the fuel cut off but if its your car then it's gonna be wired exactly the same as a starter kill just your gonna be doing it in the trunk. Thats where Ford puts most of there inertia fuel pump kill switch. These switch are put there just in case the car flips over and there no extra fuel being pumped. Also sometimes when you throw luggage or sub boxes around i.e not securing boxes, you can set off the switch and you get a no start for no apparent reason. to get back on the road just press the switch. good luck

Just to add to this, if the fuel kill goes out while driving the customer will be left without power steering and power brakes which can lead to a collision. These are the reasons why I dislike and don't recommend fuel kills.

You can still steer the car and the brakes would have enough vacumn left to safely stop on the side of the road.

But I know what your saying - liability these days.
