hi there,struggling with the dreaded non starting td5. was running fine till i changed the fuel filter at routine service,three days ago. have done the purge cycle business (5 pumps of throttle to start the auto bleed cycle) so many times i've lost count, even crept out in the dark, and repeated a few times just to surprise it, but still no joy. after each purge i use the foot to the floor whilst cranking method to bleed injectors. Now the curious bit is I'm getting smoke -from the exhaust not the melting starter, and the slightest cough of life but not enough to say she's firing, but no more improvement than that! have replaced the replacement filter just in case it was the culprit, cleaned and refitted crank sensor, cleaned and refit all air sensors, tried starting without air inlet to manifold just in case turbo pipes failing, stuck blowtorch in manifold in case heaters weren't working (won't ever use "easy start" but this works every time on the tractors). Checked ECU harness-clean, was replaced 6 months ago as was fuel pump. nice even note from pump. New battery fitted plus another one on jump leads plus the battery charger on overtime so great cranking speed.
why smoke but no fire? dont have nanocom,land rover dealer an hour and ahalf drive from me, and as rovers arent the most popular of vehicles out here, havent yet found anyone local with a diagnostic programme for them on their machines. can anyone offer any practical suggestions please

Did you fill the new filter up with diesel before you fitted it?

I'm gonna guess that the answer is NO and that you can still hear the fuel pump gugling to signify that there is still air in the fuel.

eeewwwww how familiar does that sound :D :rolleyes:
 
Not necessary to fill filter with diesel on a TD5, in fact it's recommend not to fill the filter (personally I would prefer to fill the filter). The manual states to turn on the ignition and wait 30 seconds, depress the accelerator then start (repeat 1 or 2 times). When I changed my fuel filter last week I did it the 'recommended way', no problem with starting, it started after the 1st 30 seconds but the fuel pump could be heard running for several minutes after the engine started.

I'm not denying that but on the other hand it can take 10 purge cycles before a TD5 will start after having the filter changed without having first filled it.

yer only putting undue stress on the pump tbh not filling it , did it without filling it on my 90 once and took me about 45 minutes and lost count of the ammount of times i set the purg cycle going was certainly 10+ .
sounds a lot like my problem i had with the 110 i have now, changed filter twice, new pump, new copper seals on filter housing unions, and finally sussed it in that it was the inlector seals
 
hello ratty, answer is first replacement filter not primed, second was,also bleed back line disconnected and ign on to clear air at filter.pump runs quiet for a td5 without gurgles or whooshes if you know what i mean. Have just been out for another purge cycle,- rover not me! and almost thought she was going to pick up on one cylinder, loads of unburnt fuel vapour exhaustin, but felt i had to stop before I fried the starter, crankin for minute and half, starter very hot. will give it another try in about an hour. injector washers?

Are you doing one purge cycle and then trying to start it or are you doing several in a row before trying? Have you double checked the fuel cut off switch in the engine bay hasn't been tripped? Are you touching the throttle when you're trying to crank it? What make of filter did you fit? Non genuine filters often cause problems on TD5's. Did you fit the correct filter for your landy? The tops are different on defender and discovery filters. I didn't know this myself until Buckshot had problems with his and the 2 types of filter were compared.

As it was running fine before the filter change I don't think injector seals are likely to be the culprit although it's not impossible.
 
usually do two purge cycles before crankin with go pedal all the way. yes i know i'm diluting the oil, but will be doin the oil service as soon as she's runnin on all 5. already checked the inertia switch. fuel tank 3/4 full. jeez must be doin 15-20 cycles per day for 3 days now, headin for day4!!. you don't get cleaned out that often in hospital!!!
soon be time to sneak out and surprise her again
 
hi everyone who's helped so far. Well we have some sort of success. Definitely the art of sneakin upwhen she's asleep has worked to a degree. after a few more purges and a hell of a lot of crankin we now have three cylinders firin now, - sounds dreadful but not smokin any more. as its dark and p' in with rain I'll have another look in mornin. perhaps with more patience and no doubt a load more purging we'll get all 5, then we'll see what state the oils in. after reading other threads i think it will be timely if i do the injector washers and seals anyway' as well as new crank sensor(should i be able to see its wires enterrin the plug?). I bet the techys in solihull ****ed themselves laughin whilst deciding where to put that one? New genuine filters to be fitted as well, but only pre-primed, with a hot engine and whilst parked at the top of the longest steepest hill in the area, and with several spare batteries. 3 1/2 days to do a fuel filter! will keep in touch.good luck
 
This problem only started after you changed the filter ?, and thats all ?.

If so, it seems like a big list of things to do to sort it !.

It must be terribley frustrating not be able to start it, and you are obviously struggling with fuel delivery.

Is there any chance that the filter housing could have got some crap in it whilst you had the filter off ?.

The old filter seal didnt get left on the housing ?.

I,ve never had to purge more than 2/3 times after a filter change, ( filter empty ),and dont use genuine either.

hi, re your points, am ex haulage fitter, always use masses of blue tissue paper to clean the filterbody inside and out, also washed and airlined off before removing old filter. always count and check old seals before dumping old unit. Had simmilar problems last servce though only took me a day to restart,- not enough batteries to hand. this time was deffo way more frustratin. seems to be a frequent issue but as with all things td5 whats the cause and solution with a minimal budget and no l/r workshops around?
 
So as soon as air gets into the fuel system, you,re struggling to re-start ?.

Last time, after you got it starting, you had no problems untill you changed the filter again.

Dont think that if you had a Landrover garage local, that your problems would be sorted straight away. I,ve heard of many " specialists ", that would be just as stumped as you, but charge you £ 55/65 for the privelidge !.
