Hi Prado point members - I wonder if anyone can help.
Our 2004 4.0 litre V6 auto has developed a new starting problem, it only happens when the engine is cold or if its been running for a short period of time, is then stopped and then we try to restart (and only sometimes - perhaps every 3 or 4th cold start (In QLD so not that cold)).
It follows a very strange procedure which I have read in the manual is supposed to help with a flooded/failed to start engine.
You turn the key, the starter cranks and then it is almost as if it fires on one cylinder then stops - a funny high pitch whine is emitted from the engine somewhere for 3 or 4 seconds and then the starter cranks again on its own and sometimes it does start and sometimes it doesn't.
If it doesn't start you can usually start it straight away with the next turn of the key but occasionally you have to repeat the above one more time.
It always starts perfectly well when it's warm and it runs beautifully once it is going.
It started doing this about 2 months ago when it was due a service - I replaced the plugs, oil filter etc as they were due but it made no difference. I'd say it has happening more often now so I'd like to resolve it. The car has about 220k km on the clock.
Has anyone heard of this - a friend said it might be crankshaft sensors but I don't have any OBD readers - just a few spanners and sockets and lots of enthusiasm.
The only possible difference I think I've noticed with the car is when it successfully starts there is sometimes a bit of a clunk as the starter motor disengages - but I'm not 100% certain this is new or if it is just that I am listening out more.
Thanks very much
Bob
