[QUOTE="Tazza, post: 129624, member: 82"] I don't think lean is your issue, diesels pull in a full air charge every cycle, only the amount of fuel being injected changes, more fuel equals more boom. Too much fuel to air, and you get smoke. Why did you replace the pump? i'm wondering if you got the right pump for your engine, i have been told by our '02 and '03 mechanic that the injector cam in the DI and IDI are different, is it possible you have been supplied the wrong type of pump to suit your engine? Not all V2203 pumps are the same. It can also be the reason your fuel injection is happening so late. Usually i believe there are 1 or two shims on pumps from the factory. As you have changed the pump, it is also possible your max fuel limiter needs winding in a little. It limits how much fuel your pump can supply, if there is too much, you get black smoke, but it does sound like the issue could be the pump being too retarded. [/QUOTE]
