Landcruiser problem

sonofsteptoe

Hey lads, advice required. 04 lwb 3.0 had a few problems starting recently-needed to turn over longer before it would fire. I reckoned the battery was on the way out so put in a new one. She now starts first time from cold however a couple of times after being driven for 20 minutes or so if i knock her off it'll take 3 or 4 turns of the key before she fires. Also a couple of times on tick over the engine management light has come on and she cuts out. This has also happened when going down the gears with low revs say at a roundabout. Local mechanic initially told me heater plugs needed replacing however i don't see the logic in that as she starts in the mornings first time, its only during the day that the engine management light comes on!! I've put cleaner through the fuel twice now but no joy, injectors?? pump?? anything else?? Trying to avoid a big bill before the xmas but I know she'll sit down altogether if I don't sort it soon
Thanks in advance

Get a good diagnostic unit hooked up and see what it says, it sounds to me like a fuel problem. Have you changed the fuel filter? Cleaned the in-tank filter?

hi thanks for taking the time to reply, had a service done
4k kms ago, so I know the fuel filter was done not sure about the other,
I'll make a call in the morning to find out but I doubt it as I don't recall it being mentioned at the time!! Is it difficult to get to?

Actually I am not sure if the 120 series has the same arrangement as the 90 with in tank filter.
It does give trouble on the 90 series with the tea-bag filter blocking and also the pipes feed and return corroding and allowing air in leading to hard starting.
edit: there is an in-tank filter as part of the pump assembly.

cheers CJ, Going down the cheapest route first so took off the tank and the amount of gunk on the
gause on the inlet side of pump was incredible, do'nt know how it kept going!! Cleaned everything I could
and replaced fuel filter while i was at it(not too bad), threw in a few gallons of diesel plus cleaner and I'll see how that goes.
Been told that injectors are e1200 Aaaaaaaargh

Yep. Injectors aren't cheap on the D4D, Hopefully the tank cleaning was enough!
