Landrover TD5 2.5 2000 - Non starter - Fixed #

Posted by Phil Kingdom on December 8, 2009, 5:49 pm

Year of Manufacture *: 2000
Engine Code or CC *: 2500
( Optional ) Scanner Used: solus

Hi, some help on this one would be appreciated, got a landrover td5, non starter, one of our guys here fitted a new filter housing as it appeared very damp with fuel and customer was finding occasional lack of power, once fitted the vehicle started but ground to a halt outside workshop!
Now it wont start, have carried out bleed procedure, no joy, also we cannot establish comms with the ECU even though in past we have read this one.
The wiring loom has carried some oil to the ECU but not enough to enter the ECU only the loom, any ideas?
Thanks for reading, Phrom fill

Hi Phil
Sounds like it may be the relay connection under drivers seat.Does the eml light come on with the ignition? When this relay fault occurs the eml light does not come on. There are two yellow relay's. I think it is the forward one. If eml not on just wiggle the relay and see if light comes on.Tighten the connection. If it was oil in loom you should still get comms. Also have had bad earths between battery and body which will give a bad earth to ecu. HTH
regards
Les

Thanks Les,
Had a look this morning there are no relays under the drivers seat, and providing extra earth has made no difference, of note though, possibly, is that on cranking we get a lot of clicking from the black relays in main fuse box under bonnet, the battery seems slightly low on effort this morning but will try new one.
Have read about greedy starters on this site, but I still dont understand no comms fault!
Ta for help, Fill

Hi Phil

I assume you are talking discovery as you have not found relays under seat ?

It will be worth scoping the crank signal as this is known to become affected by signals from tired starter motor, I have also known them to have a serious air lock in the fuel system, & a squirt of easy start can sometimes get things moving again with no further problems.

Can you hear the intank pump priming ?

Hello Phil,
It sounds like the fuel pump at fault to me, especially as it seems to have happened after disturbing the fuel supply. The no comms could be because the battery voltage is low. You should get approx 4 bar pressure measuring at fuel pressure regulator & obviously no aeration of the fuel.
Regards,Andrew

Well, much has developed since first post, I have since then managed to establish comms firstly with EOBD personality key but through landrover on solus, odd!
But also since then with another scanner, the code which seems most of interest in this case could be 120, can error, according to other posts on this site this code has been found to indicate fuel pump in tank, as suggested by Andrew, you can, though, plainly hear the pump working and it appears to have good fuel supply.
Any way do now have comms, and have also watched live data available in which we can watch cranking speed, does this suggest crank angle sensor is ok?
Will keep you posted, thanks for all help,
Phrom fill

Hello Phil,
although you can hear the pump running, you still really need to check the fuel pressure & quality at the pressure regulator. There are two stages to the pump & sometimes they sound ok, but still not producing pressure. Also the only reliable way to check to see if the crank signal is ok, is to scope it & check for "noise" &/ or scope the injector current supply to see if the injectors are being operated.If you are getting noise from the starter on the crank signal , you may be ableto get it to go by bump/tow starting it.
regards,Andrew.

Will be looking at this again on Monday, not much progress yet, think you are right Andrew especially as we can now get comms, hope something becomes more apparant!
Thanks for all replys so far, cheers Phrom fill.

Aha, sorted, fitted new fuel pump in tank still an absolute pig to start but once bled, all seems ok, new pump does seem quite noisy though, also fitted new injector loom as it was carrying oil.
Thanks to all for help and suggestions, much appreciated!
