Hi all,

I am having real trouble with a defender 90 2.4TD 2008, It runs fine a lot of the time but has always had a delay on the throttle. As in, when you come off the accelerator, the engine keeps revving for a couple of seconds before slowing down. This may have nothing to do with the running problem but just seems strange.
The main problem is that sometimes when you start it up, it will cough and splutter for ages until it finally cleans itself through and runs ok. There is usually lots of smoke coming out whilst all this is going on. To start with I thought it sounded like either a blocked fuel or air filter, So I changed both and there was a marked improvement but then it started to happen again after afew runs out :mad:. I then decided I would take the tank out and give it a good clean and put fresh fuel in, just incase some water had got in the tank. Again, it seemed to have sorted it out and I ran it for even longer than last time with no problems, but then it started happening again :mad::mad:!
So now I am thinking about the injection pump or injectors, but just wanted to run it past all of you other members first incase anyone else has had a similar problem. I would normally say it sounds like your lift pump has gone, but it aint got one!!!!
Any help would be much appreciated!

Thanks, Martin.
 
Is there a sedimentor ( water / dirt ) catcher in the system on older models its normaly behind the drivers side rear wheel on the chassis if so it may well need cleaning out ;)
 
The only other thing in the fuel line is a cooler that it runs through. It looks like a very small radiator but the fuel line also flows through the bottom hose which would heat it. Maybe the flow is heated and the return is cooled???
I never actually thought about the cooler though, I suppose if it had dirt in the line, it could be partially blocking the it creating a restriction in the flow.
Thanks for the reply Cornish Rattler (hell of a name!!!).
 
Just plugged it in to read any codes and its coming up with-
P1294- Injector high side open- Bank 2.
I'm going to check all the connections to the injectors now, but am thinking I need to get them all off for a clean.
