200tdi wont switch off


Recommended Posts

my 200tdi defender wont turn of when you take the keyout????any ideas... :rolleyes:

Pull the wire off the fuel stop solenoid and see if it still runs. This severely narrows things down.

Fuel stop solenoid is situated on the fuel injector pump. (not lift pump).

If ya get stuck locating it then just ask and we'll post a pic of it.

remove the fuel shutoff solenoid from the injection pump [24mm spanner IIRC] & carefully lift it out, don't drop the spring/plunger, look for very thin slithers of metal, clean these from the pump body & solenoid & refit, if it happens agian your injection pymp will need a rebuild, if it's all clean & no slithers are present the solly maybe duff, you can leave the plunger/spring out BUT to stop the engine you'll have to stall it.

use this idea's first

but if thay don't work , has the engine been using more oil than normal if so could be starting to run on it's own oil. witch would say that the oil control rings aren't doing there job propely.

..or it could just be a knackered ignition switch that keeps supplying power after the key is removed.
