    Hi All,
    06 Td5 Defender

    Attemp to start vehicle:
    Turn key to accessories.
    Temp gauge flies around to HOT
    No fuel pumping.
    Won't fire - obviously.

    Fuel pump fuse ok.

    Give it a few goes it works.

    Any ideas?

    Hi All,

    Some further symtoms from today:
    - vehicle started ok
    - as soon as l went to disengage clutch - vehicle turned off and TEMP gauge goes to HOT and FUEL guage goes to FULL.
    - I tried starting again - same thing.

    Now as soon as l go to acessories the gauges just do as above and the vehicle will now not start at all.

    When in this 'mode' - the fuel pump is not pumping as normal on acesories.


    Ideas?
    Is it earths as above post....any specifici ones or check ALL???

    Ta,
    Mike

    First thing I'd check is for oil in the injector loom, pull the red plug off the ECU and check for oil.

    Second would be the fuel sensor, they can come loose.

    Third would be the throttle sensor thingy.

    Mike, had this similar issue with a 2000 110. Turned out to be earths under drivers seat next to ABS and engine ECU's.
    Both were loose :0

    I had a few earth problems when i first got my td5 back together...

    After mucking around with a test light for a few hours, i got all the right sign's from the test light.

    but still no fuel pump. in a last ditched idea i swapped ecu's and there was sweet sound of my fuel pump.


    Maybe having a bad earth on the ecu caused it to fry?

    Thanks Guys

    I'll have a look under drivers seat - tha sounds quite possible.
    I wouldn't of thought an ECU would 'fry' itself if un-earthed?? (Here's hoping anyway)

    Its generally due to a higher current draw from the bad earth or spikes caused by the connection arcing when the connection is disturbed.
    Its always worth spraying earth connections with something like Würth battery terminal spray after cleaning and reconnecting. Very good idea if the connections are external and prone to wet conditions regularly.

    Cheers
