    V6 starting issue

    Uh oh...

    I've developed a small starting issue.

    The engine will crank normally but won't fire. Usually it will sit there cranking until I turn the key off.

    Sometime it will cought once or twice and try to start but then it dies.

    I can usually get the car to start by trying again a few times.

    When the car starts the exhaust smells quite strongly. Perhaps the engine is flooded?

    This doesn't happen every time I try to start the car and I can't pick in particular set of events that causes it to happen.

    Any ideas on what to check before I let the dealer at it? I'm not keen on giving it to them because they'll probably

    a) charge me a forturne.
    b) break something else (like last time when they forgot to tighten up the prop shaft bolts )

    Chances are it will have a crank angle sensor or camshaft fault logged.

    Chances are too that it won't be the cause.

    If you go to your dealer, get them to look up LTB00335. There's an earth cable fix if the above fault code is logged.

    Hopefully it's as simple as that.

    This sounds similar to what happened to me and a Ford Falcon 4.0 V6.

    RACQ reckoned there was nothing wrong with it other than it didn't like short journeys (I was based in Cairns) and it should have it's legs stretched fairly regularly.

    Do you do a lot of short journeys?

    sounds like crank angle sensor and your battery is on its way out

    Thanks for the suggestions guys.

    I'm pretty sure my battery is going so maybe I'll start by replacing that first.

    The strange thing is the car runs fine as soon as it starts so it can't be a major fault.

    Definetly think its the battery...

    Got the problem last night while trying to start. 3 attempts no start. Switched off lights, ac and radio and it started fine.

    Does anyone know if the battery in the RRS TDV6 is the same as the D3 V6?

    I might swap them over for a week and see if the problem occurs.

    The batteries are different but only in size/capacity wise. The 4.0 V6 is a 690CCa from memory & the 2.7 TDV6 is a 950CCa, they will swap & work fine, it will just start the petrol easier.
    Cheers.

    Well this problem started to reappear again so I subscribed to LR Tech Info and downloaded LTB00335.

    It mentions installing a new earth cable from one of the power steering pump bolts to the earth point behind the battery.

    I bought 2m of 4AG cable and two large lugs. My cable ended up being 1.3m long but it could have been a tad shorter.

    Firstly remove the engine cover (undo 4 nuts and temp remove the oil cap)


    Disconnect and remove the battery, follow the negative lead to where it is bolted to the body. This is where one end of the new earth goes to.

    Remove the top Power Steering Pump bolt. Refit the Power Steering Pump bolt with the cable attached.


    Route the cable around the vacuum pipes and along the front of the battery box. From here I was able to squeeze the cable down the gap between the battery box and the body. Run the cable along side the fuse box and secure it to the bolt with the negative battery lead. I pulled the bonnet seal back a bit to get better access to the earth point. It looks difficult but LR have left just enough room for your hands to get in there.



    LTB00335 specifically mentions that the new cable should be run as far away from the engine as possible.

    So far the starting difficulties haven't reoccurred. I'll post back if they do. But heres hoping!

    It's interesting that the engine cranks over without firing , yet
    when it does fire , it doesn't ever cut-out whilst running .
    Is this correct Dave ?
