My 2004 TD5 (170000km) has recently started to be a little slow on the uptake and has to be cranked a few times to start up. Once running she is absolutely fine.
I used a friends hawkeye recently and it flagged 2 CPS faults and a problem in injector 2 circuit (oil in loom?). I have therefore renewed the CPS and put some time and effort into getting rid of the oil at the red plug.
I have also tested the fuel pump renewed filter etc.
I think the next step is to open up the ECU and see if there is oil inside (spray liberally with contact cleaner if found?).
Any advice or suggestions greatfully received.
Cheers

SubscriberHave you replaced the injector loom?
Test the glow plugs they do bugger all, but can make starting just a bit better. If you have not replaced them all will be faulty.
After replacing the injector loom I removed the seal around the plug to the ECU so oil can run out and contact cleaned this 10 times over 6 months to no more oil showed up.

It could also be crook injector copper washers letting combustion gasses into the fuel system. You can hear the pump wooshing and gurgling from the cavitated fuel. Hence the hard to start issue.

Injector loom replacement is on the list, may be to do tonight, shouldn't take too long right?
cover off
harness out and new then in
new cover gasket
cover back on
Job done - maybe an hour?
Is there any easy way to test the injector washers?

Hi mate , A common problem with the td5 is the injector loom under the rocker cover , oil gets into them and they misfire . It's an easy fix , remove rocker cover unclip plugs off injectors , unplug main loom from front of head ,replace with new , plus a new rocker cover gaskit . Put a smear of selastic on back of head under gaskit . Klean plug going to ECU job done good luck jimr1 ..

SupporterMake sure you replace the right loom! It's not te bit under the rocker cover you need to change, its the bit that plugs into he head and the ecu... More than an hour!!!Originally Posted by Leyland1980
Agree though, replacing the loom under the cover is easy & quick, but I'd be very surprised if that's at fault.

Sorry, no easy way to test the injector washers. If they have never been done then it would be a good idea to replace them along with the O rings. Only use genuine parts. Some members see these items along with the injector loom as service items. By that I mean they have to be replaced at some stage and I agree. Not an expensive job either.

ooops hi mate , read you post , wrote my reply tapped onto keyboard , by then you had put your 2nd post ahead of mine . At least we're on the same wave length . As you say 170 000ks it won't do any harm replacing the injector loom . Also check the wireing loom under the head running along the block , those wirescan wear thrugh due to vibration , check the blind side . Ihope it works out ok for you .jimr1

Ok so whilst I think that my problems are to do with injector seals and washers ( the oil level seems to have gone up) I am beginning to get nervous about fuel pump.
What are average life spans?
Do they reduce in efficiency be fore failing or just die?
Do they get noisey before they die?
Would I notice performance issues once started?

SupporterIn my experience they start to get noisy before they die.
Having said that, they doe last forever if you dont keep the tank almost empty.
(Broad brush stroke coming up)... Farmers Defers in the UK are normally run with next to no fuel in the tank... They go through pumps pretty quickly. Those that run normally, ie empty the tank and then fill it right back up again dont normally have any problems with pumps.
