kill switch via defrost switch

I just tested this in my 87 this afternoon.

With pump ground wire unhooked the engine would not even start, parked for about 1 hour since last run. It fired a couple times but never started.

With the wire back on and engine running, I pulled the wire off. The engine died in under 3 seconds.

If 3 seconds is too long for you, simply turn off the secret switch, wait 3 seconds for the engine to use up the fuel and stop, then turn off the key and lock the van.

I have a switch under the rear seat to my fuel pump RELAY that cuts all power to the fuel pump when in the off position. Works great for security, and after a oil change i turn the engine over a few times to purge any air out of the oil system before start up.
Also just as important as a security switch for theft I have a blue sea ground switch that cuts all power (except ecu and stereo) in the van. It cuts all circuits to the ground preventing any unwanted fires. There is power running to the fuse panel 24/7 and its a bummer if someone steals your van, but it sucks a big one if your van hot wires itself and drives down the road on fire.
This guys has a removable key you can hide or take with you !.....

35 bucks could save your van!

I like the idea of the vehicle acting like it wants to start, and even trying to sputter to life, but not actually starting. You could leave the key in it and leave it unlocked (if it's relatively empty of valued possessions) if you're in a known high theft area. That way, maybe you wouldn't come back to a broken window.

It would be kind of like a sunroof. It doesn't seal water out, it lets it in and drains it. The would be thief would probably figure the vehicle has a running problem and skeedaddle off to a better prospect.

I like the idea of hiding the switch in plain sight. I took the AC out of my 87 Westy, but the switches still sit there in the dash, looking like they belong there but doing nothing. If I ran the ground wire from the fuel pump up into the dash, how could I hook one of them up as the kill switch?

I would put a diode in the wire between 87 and 86. This simple relay approach could be used to interrupt the same black wire in gas models as you intend it for in diesels. In gas models that black wire powers the ignition coil and enables the ECU relay. So this could be added entirely in the dash area and no extra wires would have to be run to the pump or engine compartment.

your key technically is a fuel pump wire interrupt switch.
you can tap the key/Ign wire at the dash to a 2nd switch to befuddle a would be thief .. is essentially the same as putting an interrupt switch at the fuel pump.

you can interrupt this circuit anyplace from the battery to the pump
pick one thats convenient or inconvenient or you can put 2 in and have both

I would be worried about how quickly you could restart the van after an accidental stall, like say if you popped the clutch at an intersection and needed to restart the van quickly to get away from oncoming traffic.

I don't see that it would affect the time required to restart the vehicle unless one is prone to fumbling.

You could wire it with a lighted rocker switch such that the switch lights up when you shut off the key, reminding you to flick it off to set the kill switch. This would be easy enough with the switches that have a separate contact for powering the switch light.

Alternatively you could re-wire the key-in buzzer to only react to a engine off but kill switch disengaged scenario. To shut it up you need to flick the kill switch to off. This could work with the magnet switch too to remind you to remove the Venus Fly trap.

In the emergency re-start (stalled) scenario just a light would be on or the buzzer going but it wouldn't impede a speedy re-start.

I wonder if anyone has considered the Velleman RFID reader?

The unit is affordable at $35 which includes 2 cards and everything you need. Can use optional key fob which would add convenience, and I am pretty sure a pickup coil can be mounted inside the ignition cowling.

This device only came out recently, so I might be the culprit to work it into a Vanagon. Seems like the ideal solution. Comments?

I have an RFID system with 2 key fobs bought on eBay months ago for really cheap, but haven't decided what to do with it yet.

Cutting the ground to the fuel pump doesn't seem like a useful thing to do unless your thief is very stupid. The fuel pump is easily accessible and grounding it to the body doesn't take long.

The PO of my van have some issue with VSS sensor(or the lack of VSS), it will cause engine to shut off. I guess some kid stole it and only got couple blocks before the engine shuts down and abandoning it.

Similar to fuel pump idea, where it mimic engine problem and not a kill switch problem plus the thief don't want to stand around when it attracting bunch of attention on the street. If right off the bat the van won't start, the thief might start looking for kill switch.
