Anti Theft fuel pump cut off, battery kill switch

i was wondering if there is anything out there for a fuel pump cut off switch or some way to kill the fuel to the engine when still running a mechanical fuel pump. Also on the battery kill switches how would i be able to have that without it making me reset my cd player every time. Any info would help need to do both of these in my truck soon thanks.

 

The fuel wouldn't be too hard. They make, or maybe made, inline valves. Turn 'em inline and fuel flows, perpendicular and they stop (like a pet**** on a motorcycle). Put it in-line, somewhere incon****uous but easy to reach. Car could be driven, but not very far.
Dad's '74 Nance Supermod had one in-line when we tore it apart. I'm sure somebody can tell you where to find one.

Obviously, you couldn't kill all the battery without resetting your cd player. My personal choice would be pulling the coil wire. It could crank ALL day long but never start.

I have also seen "secret" toggle switches up under the dash before. Unless the theif knows there is one and where it is, he couldn't run away with you're ride. It would be fairly easy to do, too.

I suppose it would be feasable to put something in-line to the starter as well, but that sounds like work to me.

P.S. the locks on my Galaxie seem to work pretty well...

 

No way to electronically shut off a mech fuel pump. I guess you could put a 1/4 turn shutoff on the fuel line.

I put a hidden toggle switch on my coil power wire to kill any ignition power.

 

Well that was easy, $9.03. Google inline fuel valve... lots of options.

i have an hei in my truck would i be able to wire in a switch for the coil wire to it that would not allow the current to flow through the wire when the switch was in the off position. i figured there wouldn't be any way for the fuel pump cut off other than the inline fuel valve

 

i found these think it would work great they are used in RV's and say they can accept gasoline and handle high enough pressure to me the 60 + shipping is worth a shot, a combination of this and the coil wire would be great they would never get my truck any where.
Electric Fuel Shut Off Valve

the above ideas are the only thing i can see for the fuel, but the radio is easy.
the thicker yellow (batt) wire is the memory for the cd player, to keep power to the radio and kill everything else, all you need to do is run the yelow wire all the way directly to the battery instead of to the fuse panel.
the rest of the wiring can be run thru the battery shut off. the radio will not come on or drain any power while the shut off in engaged because the red power is the turn on. the red and the yellow both need to have power for it to turn on.

 

I have an electric latching solenoid on my car (Ron Francis, I think). Afer I push a ****on on the entry system key FOB all the battery power is cut off - except for a little byp*** wire that comes directly from the battery that keeps the entry system, radio memory, computer, etc. alive as needed.

I have a hidden switch under my dash that interrupts the signal from the neutral/parking switch on the transmission. I also have a master battery switch in my trunk.

My current project is getting a manual fuel valve at the fuel filter. In addition to enhancing security it will make filter changes easier and quicker.

 

i like the fuel shut off better than battery, they can figure out why a car wont start, but when it dies a block away, you think they will try to retroubleshoot on the street??

 

the fuel shut off sounds like a good way. The battery switch also sounds good but would be easier to find since the battery cable would lead to it. Also the hei power wire sounds like a good way to make no spark, plus no fuel with the electric cut off. would never turn on with these two in combination.

 

Use a removable steering wheel set up, very hard to drive down the street with out this handy item, most stolen cars are picked on a trailer or flat, in most cases the wheels need to be turned or locked, makes it just that much more difficult.

 

true but a 79 gmc pickup with a removable wheel would look wierd ahahahah..

 

a 79 pickup with a cd player - Awesome!

 

On my old Pan I run a ground wire from the distributor, from the battery side of the points, thru a disconnect in the wiring harness. Looks like any wiring harness connection. So the default in order to run is that the wiring connector is disconnected. When parked in doubtfull places , I connect the ground wire so if someone comes along with a snake, the ign is grounded. He'll run my batt down, but won't start it. Thieves look for disconnects, not connects. Course, it can't stop a towtruck, or a bunch of tweeks in a van.

A bonus is that it keeps me from starting if I've had too many, as I forget to disconnect it.

 

“Anything out there?”
That’s the last thing you want (no scratch that ) you never want that.
***holes that steal cars know what’s available and will be looking for it. Invent something deviously ingenious.
I had a friend that had his stereo ripped off two or three times…that **** came to a stop when he soldered fish hooks to the last one he put in.

 

Razor blades soldered to the back edge of the housing works good too... well except for the mess, they tore up the dash, broke gauges and slashed p***enger seat after getting cut up... I think it took a couple weeks and a couple hundred to put it back together.

I had an alarm that would kill the power to the electric fuel pump in an OT car, the switch could only be reset manually from under the hood if you knew where to look. Problem was there was enough fuel to start the car and make it down the block, once the car died it was apparently tough to steer without the power steering they missed the corner at the end of the street and plowed into a parked car. One of those plans that looked great on paper...

A keyed manual Mico line lock valve on the transmission hump... maybe


A pedal jack if you have a manual trans.... maybe

Unfortunately, if a thief really wants it there is not a lot you can do.

 

how bout a manual breaker wired to the ignition...

maybe a mechanical brake on the driveshaft, with the mechanism on the underside of the vehicle.. or mounted under or behind the seat..

 

I would not do that with the hooks and blades, if they cut themselves up they will burn the car down to the ground on you, seen it done. I would rather lose a stereo or a battery than have the J bags torch the car.

 

Like oneeye has said,I have my yellow radio wire direct to the batt. and a hidden power shut off switch.Just remember to disconnect for storage. It is a damm same we have to worry about some piece of **** stealing your pride and joy ! Sure hope they find the ***hole that stold the truck in Texas,and let the local boys take care of his *** !

 

Kill switches are nice and it is a measure toward security..
but to a pro, and the thefts we are seeing these days, the kill switch is not stopping them.
After its loaded and taken to where they do their dirty work, they have time and ways to find the switches. or make the keys , or...strip it, and at that point any theft deterrent is found or eliminated.

I think GPS is the way to go, for now.
but time is of the essence, if You dont notice it gone, or You rely on someone other than you going after it quickly..the GPS will be found or the car ditched..

Pressure,and immediate pressure when the car is stolen will be the only way you can be sure you will get it back.

or an early silent warning alarm and GPS , so it gives you time to lock and load

 

yeah the lojack system is nice for sure. I need to do something soon to my truck so i feel a little better about it being out all night. But its true if they really want it they will take it.

 

i really think that no matter how far one would go to kill the battery or fuel if some car jacker really wants to take the car/truck that bad they are going to get it no matter what you do...........

 

im not sure what you want to accomplish here but if its just anti-theft i think i have a good solution for you:

if you have a detachable face plate radio heres a great option:

Kill switch for detachable face plate makes it so that the car wont start with out the face plate in, you will have to cut the starter power wire at the column or somewhere along the wiring harness your choice . Buy a SPST or SPDT 4 pin relay usually about $5 bucks at any auto parts store, basic relay. and wire as follows,

Pin 85 ground
Pin 86- solid blue wire from back of radio power antenna wire ( only has power when the faceplate is on and the car is on.
Pin 30- first side of starter wire
Pin 87- other side of starter wire

The relay will only have power and connect the 2 sides of the starter wire when the radio faceplate is on.

or a kill switch useing a cigarette lighter,

This one requires that you push in the cigarette lighter when you want to start the car. very few if anyone would think of this and if you take the lighter with you it makes it even better. same relay as before but wired as follows

pin 85- +12v power ( an easy way to do this is the power wire that would have run your lighter)
pin 86- the end of the wire that goes to the lighter you just cut for the previous power
pin 30 first side of starter wire
pin 87- other side of starter wire

 

how about a diagram?

 

easier solution: Sleep all day, then sit on front porch with a 12ga semi-auto ****tergun across your lap, a .45ACP pistol nearby, cover yourself with an old dark-colored poncho....and wait.

Of course this requires some alternate source of income, a fertile mind (you'll have to do a lot of daydreaming) and a total lack of concern for anyone's safety.

Wire the starter solenoid/ignition switch so that it only receives power when the headlights are on.

If they want it, they will get it, but anything you can do to slow them down may cause them to move on to easier targets.

 

If it's an HEI, forget the ignition cut relay. "Back in the day" I used to carry a 6' piece of wire with an alligator clip and slide terminal on it. That and a big screwdriver will have an HEI engine running in under 10 seconds, guaranteed.

If you're worried about the CD player, hide it and put a stock radio back in the dash. The best deterrent is making the vehicle look like there's nothing a dirtbag can make a quick buck on...

How are things in Visalia these days? I lived there from 96 to 2006. Nice little city.

 

Here's an inexpensive GPS trick, from Brian Fuller. You need an old cell phone with GPS an it's car charger. Plus a cig lighter/power point receptacle to plug it into. Trick is to hide all this out of sight. Turn off the ringer & disable the vibration mode. I would encapslate it in foam myself. Cell phone companies offer plans where you pay, only for what you use. So if the vehicle comes up missing, you call the phone enabling the GPS. A friend of mine has a phone application that shows where his friends are at any given time. (it requires you to give him permission, before it follows you) So you'd actually be able to trace the stolen vehicle/motorcyle.

Lojack you pay a monthly fee, like a retainer for the polices services if the vehicles stolen. (Tax dollars couldn't possibly pay for that.. don't get me started!)
