Has anyone installed a fuel cut-off switch under the seat or dash that would not allow the car to be driven any distance without "running out" of gas, and if so, where was it run to and how was it done? Thank you.

Works if you have an electric fuel pump. I cant think of a way to stop a mechanical fuel pump from working without a little valve in the gas line. If you have an electric fuel pump just route the wire under the seat, and install a switch so that it wont run unless the switch is on.

This wont always stop the car from starting (if its a carb engine) but youll get far enough down the road on the fuel thats in the carb to get you onto the middle lane of the freeway So remember when you use it!

Two small things you can do,
1. a hidden battery cut off switch
2. remove coil wire and take it with you
A few other things that work.Leave a big *** dog in the car.
OR take the car with you every where you go.

Thanks. I like the idea of the battery cutoff switch, but then would I have to recalibrate the electronic speedometer every time I cut it off?

No I'm sure you could wire a by pass so your radio mem, and speed-O have power all the time.

No good Ron, had a buddy that used to do that all the time with his cougar, when the car was found, they had just pulled a lead off and used it as the coil wire, the car probably ran like sh!t, but you can still drive it while it only runs on 7 cylinders. They had stolen the, tires and wheels, hood, trunk and windshield . Bastards like that should be shot.

That's why I always removed the distributor rotor. Car won't start, and it's not obvious what's wrong when you open the hood.

For the fuel pump you could just mount a toggle switch in line from the pump to the power source. I have one on my '70, but not for anti-theft But I have used it for such purposes), but just so I can turn off the pump when needed.

John from what I've seen 1st hand.If they really want your car they will get it.No matter what cut off's or what you remove.
The only way to be 90% sure no one will take it.Is to never ever leave your car.
It's all a matter of making your car the least easy to steal.
Park in well lit areas,try to always park were you can see the car,dont leave items in the car where people can see them.Park near other cars that are even more desirable them yours,that part is easy for me.

You are absolutely right Ron, I don,t know that there really is a way to safeguard your car if somebody is dead set on taking it. Like I said before those bastards should be shot. I kinda have a feeling that Stewart would be first in line holding the gun.

Right after he showed how the "CLUB" was made to be used.I think if Stewart and seen them trying to steal his car.There would be a few less people taking up space today.

Any theft makes me mad,go out and buy our stuff like everyone else.

I try to never leave my car anywere I cant see it.I'm real lucky to have a garage for it.

For those of you with a MSD6-A, the box comes with great kill switch. On the top of the box, next to the tach output, there is a connector with two wires (a green & a purple one). If you ground one of them (Depending on the wire you are using for triggering the box)the ignition will be disabled.

I just installed a regular wire connector under the dash next to the ignition switch. It must be disconnected for the car to run

Those of you with manual trannys can find the wires that would go to the neutral safety switch on an automatic, put a switch on those two wires and you have a kill switch.

A good hood lock goes a long way. 65/6's are a bit difficult to lock, chain, cable lock, etc. I made a very simple locking device for 67/8 that is foolproof-you better not lose the key! Then, you do your disabling under the hood. A fuel shut off, battery shut off are very good. As for the flatbed gang, Stay out of flatbed prone areas. A good deterent is a brake lock that keeps the brake pedal inoperative. The newer cars require the brake pedal to be depressed prior to engaging the trans. Possibly, a switch that requires this and a brake lock. All of these things are deterrents-slowdowns-not absolutes.

.......& make sure you have the key handy in case of a fire. A friend of mine lost his 69 because by the time he found the key the hood was too hot to touch

Couldn't a coil cut off be installed as well? Leaves the battery, to keep power to things that need it, but no spark.

I've been thinking about a hood lock for my 67, do you have any pictures of the one you made???

Hey Fellas, Ron has some excellent ideas and is right about if someone really wants your car they'll take it. I have to add some to Scoops suggestions as well.

-Car Cover, people can't steal what they can't see. A bit much for the parking lot situation but great for home.
-Multiple kill switches at various different locations. Who the heck would know the combinations of which switch needs to be toggled which way?!?!
-Hood locks (Cables, chains, hood pins, etc)
-Clubs for brakes/steering wheels (if a novice thief is scrolling down a row of cars, he's bound to pass this up. I used to be a kid and had thug friends too ya know? )
-Alarm, also good for the novice thief.

Ron, even if you stay with your car, the ever popular method of carjacking at gunpoint is also a popular situation. And at that point, you better let it go or use Todd's idea of S&W!! I love S&W, their guns are great regardless of what all the H&K and Sig lovers think.

Hi Folks,
How 'bout instead of just taking the coil wire, you keep a dumby wire (with no conductor) that looks just like all of the other ignition wires to put in place of the real one. Even a marginally intelligent car thief would probably not figure that out for a while. Just don't confuse which one is which.

Haha. I haven't bought a Sig yet -- they're big bucks by college boy standards, but hopefully I'll be picking up a P229 in .40/.357 (I'll get both barrels) later this year. For now, a 686+ .357mag keeps me company when I feel the need.

Here's an idea for a low profile cut off switch. Use a fuel selector valve from a 73 chevy truck with dual tanks. It is a solenoid type valve, that has two inlets and one outlet. One inlet is open when the coil is de-energized, the other when energized. You could hook it up in the soft line by the tank. Wire it to an ignition hot only line witha hidden switch. Outlet goes to the front of car. Inlet that is normally closed is capped, other goes to tank. That would take someone quite a while to figure out.

Thanks one and all. Found out a friend does business with a company that makes a solenoid type valve just for this application. His son installed one on his Mach and you have to know where the button is to open it. The only problem is that if you forget to turn it on you can stall out in the middle of an intersection after you start up.
