Diesel engine re-start button.

Yep, that sounds like it.

I have located it. Large red button at the back.

So my car has it, but later models and petrols don't? That will save me time from hunting around on my next car.

Thank you all.

All injection petrol engines are required to have one.

Not often you get one on an old diesel though, diesel is pretty harmless stuff at atmospheric conditions, even it did leak in an accident, I'd be more worried about slipping on the filthy stuff rather than it spontaniously exploding.

Yeah, for some odd, and pointless reason old Peugeot diesels have an inertia switch.

Should be pretty easy to spot.

Pointless because the emergency services would rather work on a vehicle on which the fuel pump is still pumping out fuel and risking a fire, rather than one that's electrically dead.

Don't know about that, but I'd rather be trapped in one waiting for emergency sevices that wasn't pumping 10 gallons of fuel over me.

Why would the fuel pump be running? These engines have a mechanical lift-pump, once the engine cuts out, no fuel is being pumped. Unlike an injection petrol engine for example, when fuel is pumped by an electronic motor, which could stay engaged after the engine has cut out.

I certainly can see the point of intertia switches, just not on old rotary pump diesels.

Also, as soon as a diesel line is ruptured the engine would cut out anyway, so I stand by my point that on these engines, it's pretty pointless.

Some diesels have electric lift pumps in the tank, as well as the mechanical pump, other inertia switches trigger the cut off solenoid on the mechanical pump, to shut the engine off, if the return is ruptured it'll still run, but still pour fuel out.
