Hard starting
Hi All, my TDV6 has a starting problem. If the car is left standing for a couple of hours, it takes 4-5 seconds of cranking to start. No smoke and runs perfectly after it has started. If I shut down immediately after starting on cold morning It fires up immediately even after an hour or so, so it can't be glow plugs.
This leads me to believe its fuel related. I have checked the LP pump and it pumps (Checked through the valve in the engine bay), the HP pump is obviously working as the car drives fines.
Any ideas?

Fuel filter?It can when others can't,
It will when others won't,
It goes where others don't.

Could it be the fuel filter if it runs fine, even at maximum revs?

My D4 takes a few seconds of cranking from stone cold - it is a diesel after all - that stuff takes a bit of heat to get it burning, heat from the glow plugs and from compression.
I don't think you have a problem Stew,

Thanks but still think something is wrong. It appears to be getting worse, albeit slowly.

Does it actually crank over as fast as before?
An ageing battery will give poor cranking speed and insufficient amps to the glows.

d'yer ever here an occasional "tinny" kind of noise upon start up that is there for less than 5 seconds?
If so, starter motor my friend...had similar ie on the odd occasion it would not fire up after waiting for the glowplug light to go out...then as the weeks progressed had a intermittent tinny noise as if one of the heat shields was fibrating.....eventually it made a tinny noise one more time after stopping to fill up..and that was that, key would go round but car would not fire up.

Battery was the first thing I replaced, the motor spins plenty fast enough.
No tinny noises either.
Can't help but feel its fuel related, like the injection system is draining back and is taking time to prime before starting. What would cause the fuel to drain back into the tank?

I've never had an extended crank on any healthy D3 or D4 I have every driven. My D4 starts as soon as the glow plug pre-warming is completed on the shortest possible crank.Land Rover - Turning Drivers into Mechanics Since 1948
