Couple of easy checks.
Make sure the battery is in good condition. TD5's can play up when starting if the battery is down on power especially as the ecu dictates fuel feed to the engine. Check all the relays under the drivers seat are firmly seated. One is for the fuel pump etc and can be problematical. It does sound like some form of fuel feed problem, pump, air getting in the system etc. Having spent almost a year tracking down strange problems on my TD5 I have now worked out that the not so obvious things do cause strange problems. Might also be worth pulling the crank sensor to see what sort of condition that is in. Good luck.

Injector seals would be a good start, perhaps see if there any leaks (of fuel out) around the fuel pressure regulator or cooler, anywhere high up on the vehicle. If the filter hasn't been changed for a while, it might be worth putting a new one on with Vasaline on the seals, just in case the fuel is draining down from there (not so likely). Pre-2002 MY TD5's are more susceptible to low battery voltage on cranking (10.5V) so a really good charge and condition cycle of the battery would rule that one out. Now's the time of the year for battery problems. Roads? Where we're going, we don't need roads.

Thanks chaps, very much appreciate the replies, I've only had time to have a very brief look under the driver seat today (was brewing a beer, priorities!)
To my untrained eye it looked very neat and tidy, no rust etc but a couple of drops of oil. I felt under the red ecu socket and there was oil so I guess it's suffering the injector harness oil problem I've read about. I suppowe this could be a red herring with regards to the start problem but I guess worth sorting while I'm at it. I'm going to check the relays too as soon as I get chance. I'm going to order the injector seals, rocker gasket and injector loom and plan to do it all next weekend, it appears to be a task that a relative New comer can attempt. Any pointers or tips appreciated but I'm planning on taking pics and doing a kind of step by step thing so you can see my 'handy' work and comment if I've messed it up!

Hi Tom
Oil in the harness is probably the most important thing to do first, it causes many problems If there is oil coming out of the red plug be prepared for a week or so of cleaning the plug to make sure all residual oil has gone. Get some spray contact cleaner to help get rid of it. I would hold fire on the injector seals. If you do replace them get genuine and make sure you get the O rings as well. There are plenty of write ups on the web about how to change them, just be very careful when removing the injectors, don't use force as it is possible to damage the head. When putting the rocker gasket on make sure the rear crescent is seated correctly, they are notorious for leaking. Harness and rocker cover should take less than an hour to do. Cleaning the residual oil out of the harness takes as long as it takes the oil to disperse. Good luck.

Nice one bob one more quick question with regards the ecu clean up, when disconnecting the red socket do I need to disconnect the battery first and if so I have read about it affecting central locking fobs? Something to do with disconnecting it within 15 seconds? Is this right?
Again I really appreciate your help. Michael was just telling me a story about a friend of his who slept with a land rover, lonely nights in the desert.. |

No need to disconnect the battery to remove the ECU plug but you may feel happier doing the clean up with the battery disconnected.
To disconnect first loosen the NEGATIVE terminal, then key in ignition and turn to position 1, handbook says position 2 but on mine (and a few others I know of) that is wrong, then turn off and remove key and remove negative battery connection within 15 seconds. Then remove the positive. To reconnected, positive on first then negative. If you follow this procedure the fobs should be fine.

Finally got round to buying the parts for this job, hope the kids like the Christmas presents .
Ive got a new injector harness, injector seals and O rings and a new rocker cover gasket. Hopefully I will get time over the coming weekends to get this sorted. I was just wondering if this would be an ideal oppurtunity to carry out any other work, things thats would benefit from these new parts? Nothing major just basics.

Probably worth just sticking to the parts that you have got, and fitting them really well. There isn't a lot more that can be done inside the cam cover, and with the TD5, if it works -- leave it alone!
If your problems are still there after you have done these bits, it will be easier for others to help if you have limited the work to a small group of parts Roads? Where we're going, we don't need roads. |

Good point, I think I was getting a bit carried away. Michael was just telling me a story about a friend of his who slept with a land rover, lonely nights in the desert..

Just 're-fitted the injectors, in the process of winding the engine on manually to adjust them and I can hear a squelching noise when I'm winding it, I didn't get that noise when I was removing them, is that normal?

Yes it's the gases from compression, getting passed the valves as they start to open.
don't worry, it'll be ok Andy |

I had similar symptoms and it was the fuel pump. It would work intermittently. The fact that you said you've used the five press priming method makes me think that it might be a perfectly serviceable pump. If it's intermittent, here's what I did:
If the fault is still there after all your injector work, make a conscious effort to listen for the fuel pump priming when you put the ignition to position II. If you cant hear if, give the fuel tank a few whacks (hit the steel tank guard!) with a mallet and see if you can hear the pump begin to prime. Mine did this, fuel pump replaced and running fine now. |
