I had a more extreme version of this problem, the engine wouldn't start at all if left for more than 4 hours. It turned out to be the air bleed valve in the rear facing, outside union on the fuel filter housing. If the tank is completely full the problem shouldn't occur as the return fuel line...

I filled the tank to the absolute brim, and hey presto problem gone. Pump is now silent prior to cranking and it starts and runs first time. I can only assume that the missing Air Bleed Valve is the cause, and that fuel is draining back to tank over a period of time, but it can't do this if the...

Thanks for all the comments guys, really helpful to tap in the landyzone knowledge base. It still takes a minute or so of cracking to get it to started with the new battery, because the Air Bleed Valve is missing, I thought that the fuel may be draining back to tank after a couple of hours or...

Next Update!! Battery died and would not charge, got a new one and I can now start the TD5 with no easy start, I don' think is due to solving the problem rather than it just give me a much stronger, longer crank. I put a new fuel filter on as well. I may get a fuel pressure rebuild kit a long...

Will get it read on Monday, and have ordered the Air bleed valve as its definitely not currently present. Battery is dead now!!

What I don't get about this problem is that it doesn't start after the fuel purging process. If air was getting into the system, or if there a pressure issue then I would have expect the purge to sort it. As mentioned it will start on easy start, and once run up it will start just fine until it...

I've just taken off the two rear unions on the fuel filter, there is no non return valve, or air bleed valve present. I assume that I should as a minimum have the air bleed valve!! I have removed the EGR using a kit.

I should add that the fuel purge process doesn't seem to help at all, nor does leaving is on ignition 2 for 30 seconds.

Will get a new loom ordered. Once started and run, it will start just fine again and again, its only when it has been left for several hours, to me this sound like a fuel pressure problem. I'll look at replacing the air bleed valve as per the thread you linked.

Hi All, Not had to post on the forum too much as I never had any problems with my reliable 200TDi, I now have a TD5 and within a week I have some problems. The TD5 will not start when is has been left for more than 4 or 5 hours, to be more precise it will start and then die after a couple of...

I also use Lancaster - £111 for a '93 defender with 3000 limited mileage. Was pleasantly surprised when my recent renewal was less than last year:)
