    Now desperate for ideas! 300Tdi Overrun cutting out problem!

    It doesn't turn over at all to start with. I Wasn't in a position to try by hand (on the roadside) but one time I had three people with me and we bump started it ok (resulting in obligatory smoke!). The pump has one wire (stop valve) only.

    Now desperate for ideas! 300Tdi Overrun cutting out problem!

    OK, Never any smoke emitted at all during overrun so I would normally discount valve guides, turbo bearings...However, if vehicle is allowed to decelerate until stopped with the engine "cut out", it will not turn over on the starter. I have to wait 5-10 minutes, then it will turn over (but...

    Now desperate for ideas! 300Tdi Overrun cutting out problem!

    Hi, I was leaning to the overfuelling idea myself as the mpg is not brilliant on long, fast runs and the dipsick hasn't moved for 3000+ kms. There is no EGR or sedimenter fitted. I don't know too much about diesel pumps but wondered what might make it overfuel? "The rack not closing down"?? Is...

    Hi, The disco always starts "on the button" and cruises for hours at 70-80mph up hill and down with no loss of power (just "cuts out" when decelerating to leave the Mway and smokes like hell if you try to "catch it" by jigging the throttle)

    Hi Thanks for the reply. I hear (and see!) what your'e saying but surely any oil would be drawn past rings, tubo bearings, valve stems etc. whether or not the ign was on or off and both situations would result in smoke?? I don't get smoke if I turn off ign whilst decelerating from 70mph to 30mph...

    Now desperate for ideas! 300Tdi Overrun cutting out problem!

    Hi again, I just tried something which I think may narrow the problem to the injector pump…Was driving at about 3500rpm (on straight road, no traffic etc.) and I switched off the ignition (and so pump stop valve). I didn’t touch the clutch but allowed vehicle to slow under engine...

    Now desperate for ideas! 300Tdi Overrun cutting out problem!

    Hi, this is my second post for this problem and I desperately need some ideas/things to look for/check. Briefly, the Disco runs normally in traffic (low engine speed/low throttle openings). On the open road, after driving at 50/60mph, if you take your foot off, the engine “dies” on...

    Engine dies on overrun then too "tight" to start??

    Help!:confused: Gotta strange problem with my 300tdi disco engine. Started about 18 mths ago when coming off a motorway and decelerating down the slip road when I realized the engine had died. Flooring the throttle during overrun produced lots of smoke but engine would not restart and we ground...

    Hello:) I've had land rovers since I first bought a V8 3-speed auto, 2-door R Rover 30 years ago. Brought it to France when we moved here to start our campsite 18 yrs ago where it was immediately stolen! Replaced it with a FR regd 2.4 VM RR which blew-up dramatically 2 years later in 1996...
