Hi. Me and a few mates have just put a 200tdi in my defender. On idle it sounds fine as soon as you apply throttle almost full it pops and crackles. People have been saying lift pump so we changed that. Done Injectors. Timing. Any help would be much appreciated. We think it’s a fuel problem maybe starving itself of fuel. But I would imagine this is the place to ask a lot more experienced people on here.

Yeh that’s odd. I would tend to agree and say a fuel issue. If you’ve done the injectors and pump just got to work backwards from them.
any help is appreciated mate expert or no expert I’m quite enjoying learning from all different answers. Thanks mate

turbos give the required back pressure. My tdi ran just fine with no exhaust when I rebuilt it
but surly if it’s revving up it still shouldn’t sound like that with or without load ?
Is that an easy fix

If the engine has just been started it is quite common for an old engine to miss some until a lazy pot warms up. This can be because a cylinder is down on compression or its glow plug is not good. What a load does is warm it up quicker.
Has the engine been stood for some time before being fitted ? Did you see it run before it went in your truck ?
Not easy fix, but mine still revved ok and didnt smoke once warm so l suspect yours is fuel or pump timing
so we have had it sat for a bit but we have also now had it started for a while like it’s been started a few times now and still sounds the same. And yes we seen a video of it running etc and it was fine.

Having watched the video several times now I still recon one or two pots is not playing right. Possible causes. down on compression, stuck rings, no glow, injector faulty [ even if new ], as Flossie says banjo's the right way around, timing out, the 200 will run even a tooth out.
Okay thank you. What would you say to start with or is it something you can fix for example. What would you check next. Sorry for the questions thank you
Start at tank sender, remove it and check then go forwards and remove/check every part, never assume its okay even if it was ok last time you looked or if its new.
If you have seen a video of it running nice, then your installation must have an issue
New fuel pipes? New fuel filter, or is the old one still in place, what about the sedimenter?
What engine was in the car before?
