Can anyone recommend a simple but effective theft prevention system by disabling the engine of a diesel vehicle.

I am unsure whether the commercial units on the market are suitable for diesels.

Are you sure? Sugar only disolves in water so as long as the grains do not block your filter it should not cause any problem. Another old wives tail I think.

Sugar may only deslove in water but it gels in petrol. Th egelling is what makes it gum up.

plus the fact that you fill the tank full of the stuff, it would guarantee to work :-) ....helps when you live in a Cane grower area ;-)

Hi Chris the immobiliser should interupt the power sopply to the injector pump shut off solenoid as well as the starter circuit. This will be no more or less effective than cutting the ignition circuit on a petrol engine. I really boils down to the quality of the immobiliser and how well the wiring is disguised when it is fitted, I would always reccomend fitment by an Auto electrician.
Regards Ken.

Thanks Ken. I'll keep your comments in mind. I am thinking the activator/switch will need to be disguised or hidden in clever way. I am thinking a warning light on the dash would also be helpful. Probably best to just find a reasonable commercial set up.

Modern immobilisers or alarms are cheap, easily installed by auto leccy or car stereo dude and are suitable for petrol or diesel engines.

Chris, My GU has NATS [Nissan anti theft system] with central locking added.
Basically NATS means you can't start the car unless you have the ignition keys that came with the car. The keys have a small electronic transponder built-in, and unless the correct key is within a few inches of the ignition, it will not start.

The only way a new key will start the car is if you take the car and the key to Nissan and they electronically code the two together.

And guess what? The only place you can get a key is from Nissan......so remember guys, when you go on that big holiday, take your friggin' spare keys with you!

There are immobilizers available with the same system, only the transponder is in a small plastic ball which is kept on the keyring.

I don't like the ones where you have to press a button before you want to start the car, they re-set themselves after 25 seconds or so and you have to dissarm them to start the car, even if you were just waiting in the car while the missus is buying some milk at the deli.

As I said above, it is a good idea to take your spare keys with you, and keep them in the wifes hand bag or hidden in the car somewhere.

The last thing you want is to lose your keys in the middle of nowhere and you have no way of getting the thing started!

Be careful. Muzzgit. That's the same BS that I got with my 100 series TD 'Cruiser..........."the keys have trasnponders that talk to the engine, it can't be stolen, only a Toyota dealer can get you a new key,,,,,,,etc,etc.

Then someone stole the car from my driveway.

The stories all changed then didn't they............."Oh yes, they can be stolen if you know how, yes we've been having a lot of these lately, 100 Series - easy mate, gone in 1 minute and 30 seconds"

Yes indeed Bilbo, all it takes is someone who works in the motor trade to be able to get a key and have the bizzo done and they also know where you live 'cos it's on the invoice !!!

They wouldn't wanna get caught !!!

Muzzgit,

I'll never be able to prove it, but I'm convinced that's exactly how mine was stolen. It was an inside job.

You could wire in a hidden switch attached to the starter soleniod or one on a soleniod valve of the fuel system, another possibility is a battery isolator.

I got an auto ecectrician to install a simple switch that cuts off the glow plugs i think. Battery will crank but not start. easy switch under the dash.

I would much rather have had him drive himself for six months and do his own thing instead of working for me .One would think that a uni educated person of 34 would know better. You do have these things to look forward to,as they never seem to grow up.
Back in the old days you could give them a good clip around the ears and send them flying, but today they are to big and hit back.

Any way i must be off to do some work and try to support him and his mother , who both still live at home .

Have fun with your kids

The cheapest and most effective antitheft system in petrol vehicles in days gone by was to lift the bonnet and remove the distributer rotor button and take it with you , remember that in dads diesel trucks he always had an inline tap mounted under the bonnet prior to the fuel filter ,unless you knew what and where exactly you where looking for you would never know.

Hi Chris D,
I have a Black Widow system which is an alarm, central locking and immobiliser on my 4.2 Diesel.
Works fine and the wiring loom is all the same colour (Black) so that would be thieves have to figure out which wire to disable to to get the thing started.
The control unit is mounted in an out-of-the-way location also. You can't get at it without tools to dismantle the dash.

Worth the money? You betcha....Its been in for 2 years (next week actually) and has not been a problem.

Chris Probably the only ting you can do is what Alloy c/t said about having a valve hidden in the fuel line to stop fuel flow

Trouble with Mechanical injector pumps is all you need to do is supply 12volts to the fuel cut off solinoid and it willl run regardless

Keep in mind if you do install one make sure YOU know how it works and how to by pass it

Last thing you want is to be in the bush and have immobiliser problems

I heard of someone with toyota fitted immobiliser that played up and wouldnt activate the solenoid on the fuel pump so they ripped out the wiring and bypassed it and were on their way in no time.

I think the best way is multiple deterrents so as a thief overcomes one obstacle another appears.

You should also understand how they work in case they play up in an isolated area.

I have one fitted to mine (piranha), It has been set up so that as long as i have the button in my reach, if someone was to drive off while engine was running, i can press the button and it kills the engine. BUT like anything designed to stop a thief, if they really want it, they will take it no matter what. Learning the wiring setup of an imobiliser is not so hard for any thief. even now with the new systems where all the wires are black in colour, its still easy enough for a pro to get through it in a short space of time. This aside, it all helps having one fitted.

There are heaps of good quality immobilisers available for diesel powered vehicles. They are fitted as standards equipment now by all vehicle manufacturers even on the latest Hi-Lux which is one of the last diesel powered vehicles to have them fitted during production. Immobilisers have been required by law in WA since July 1999 in an attempt to reduce vehicle theft and one of the best types is the .Cyclops brand where the transponder hangs on your key ring and is close as you will get to it being in the head of the key as the factory installed ones are and that way whenever you insert the key in the ignition the vehicle will start without having to press buttons or plug in touch key transponders, etc. The other types can be a pain at times as in WA it is a requirement that the immobiliser "self-arms" within 38 seconds to ensure the owner does not forget to do it when leaving the vehicle
