engine doesn't shut off

The second half of the post was actually an explanation of the 'energize to stop' system (to contrast it with the energize to run system explained in the first half of the post). I used the MD22 as a real life example with a similar problem to the OP.

I was trying to give a complete picture in an effort to help the OP (and anyone else who happened to be interested).

Got a problem with a D3-110 you wnat to know about how the system works on a D3-110 not how it works on MD22

There is no criticism that can be levelled at the OP.
He knows he just switches it off to stop it.
In fact he is to be commended for having read the manual knowing about the emergency stop button!

Md22 is really not the best example of engine to use as a typical Volvo as its rebadged unit which has an unusual electrical system in that it is a combination of earth return and insulated return.
 
On my Perkins Prima (M22L equivalent) there is a relay between the control panel and the stop solenoid.
So before you go out and buy an expensive solenoid you should check that the relay is working properly. Even if it clicks there may be contact problems.

yesterday my volvo d3 110 started as usual (key not button) , but it didn't shut off simply by turning the key . I used the emergency shut of button on the engine.
I changed the key and its mechanism but no success.

any idea?

Sure others have said this-cut off solenoid usually on the injector pump-stuck/failsafe in open position.

Indeed they have, but it doesn't have one, nor indeed the old fashioned type of pump with a stop lever that could be controlled by one, it is a common rail engine and is electronically controlled. The fact that the emergency stop button killed it leads one to suspect that the only thing close to a solenoid, the fuel valve (which is confusingly called a solenoid valve) is in fact working and not recieving it's signal to shut down via the HCU or ECU when the "ignition" is turned off.

No, it's a stand alone valve linked to the ECU not a solenoid that simply pulls on the stop lever of the pump instead of a cable.

Solenoids are solenoids, coils of wire with a metal slug inside, whether it pushes or pulls a rod or moves a diagphragm, they are solenoids. Not confusing really. To stop the engine the solenoid moves and shuts the flow of fuel, common rail or piston pump, or swash plate, it doesnt matter.
Now what controls that solenoid is another matter!

Without wishing to get into an argument about semantics that is really what I was getting at, a solenoid is a separate thing, the D3 valve is a self contained device containing a solenoid which is not a replaceable item like on an old fashioned pump. It’s a bit like what people sometimes refer to as a starter solenoid, often (not always) its not, but rather an electrical relay operated by an internal solenoid, another specific device, the same solenoid can be used to operate varying devices, a relay can only be used as a switch and a valve with an internal solenoid can only be used as a valve.

stop digging, im just winding you up a bit!
Point I was making, the solenoid aint working. On an MD22 you can buy a golf one for peanuts as compared with vp prices, on this one it aint going to be replaceable with an automotive one.
The point you make about it being a common rail engine means that the solenoid that i have hi lighted is (if it is a similar system to a peugeot one) not only a fuel shut off device BUT a fuel flow controller! Therefore it means that if the engine is running (And you can shut it off manually) then it is the electronic control that is not working correctly. If he has changed the ign switch then I presume we are looking at "black boxes"?

Yes, as I said either the ECU or the HCU, I'm not sure which would actually control it which is why I suggested a check on the fault codes, unless like me he has a VP LCD instrument display / fuel computer which displays fault codes then I expect the code will need to be read by a VP agent or at least somebody with the Voida kit. My origional advice to the OP stands, there is and was no point poking arount looking for a "solenoid", because there is not one to see.

The D3 is a marinised version of the 5 cylinder Volvo car engine (D3 / D5 variants), so it is quite possible that it *is* an automotive part (but may well not be the cause of the problem, or cheap....).

I suggest the original poster asks the same question on the MoBo forum where there are many more people with knowledge of these engines, including a few professional Volvo trained Engineers (no disrespect to those posting here).
