200TDi power loss when warm

(1/4) > >>

Fizzy Pig:
I got my Defender (the Fizzy Pig) a couple of months ago and it has a low mileage 200TDi engine in and I have just had her serviced to (and new fuel tank). She starts fine everytime but when she gets warm I lose power and in top gears, usually in 4th & 5th @ 50mph and she has conked out on me a couple of times.

Undoubtably fuel starvation. She does seem lumpy when warm/hot to.  Cold she is right as ninepence. And I have had her off road all day long no problem including towing a dead Disco up a 40 degree hill like it wasn't there.
So bottom line, cold and in low gears/speeds fine. Just as she gets warm stutters and sometimes dies when doing 50ish.

Is there some sort of temp detector or fuel control mechinism associated with the temp? Any ideas guys or anyone had similer?

Cheers :? [/img]

Sounds like the fuel lift pump is dead. A replacement is about £25.

Wizard :twisted:

Fizzy Pig:
If it was the fuel lift pump wouldn't this affect the preformance going up and down steep hills off road? What are the general symtoms or ways to prove if it is the fuel lift pump?

I'll be chuffed if it just £25 to fix her. Another dumb question but what top speed would you expect from a 200TDi 90. I can just get 60 at best. (never had a deisel before as I had a 3.9 V8 Rangie prior to this)

Cheers

I would check all the fuel lines to make sure they're not squashed anywhere, check for a breather on the tank and make sure its not blocked, i had a tractor that had a blocked tank vent which caused fuel trouble by creating a vacuum in the tank as it used more fuel which was in effect pulling the diesel back to the tank, check lift pump as wizard says also, does it start again easily after stopping? did it do this before the tank was changed?

hobbit:
Another thing if they have them fitted. I'm talking on a 200tdi disco mind you, they have a sediment/water trap unit under by the tank, we had one in  recently with contaminated deisel, had to drain tank and replace fuel filter, then finished up bypassing this unit as it was seized solid and would not work, once bypassed no probs
