Never remove lines, pumps, injectors, etc unless all your troubleshooting indicates a failed component. Hard starting and smoke at start-up indicates to me low compression or incorrect injection timing. removing diesel injectors from a OM647 engine with the Injector puller tool but not pulling the tops of the injectors. But if not, you can rely on a mechanic to make their way to the EMC and plug in a Flash tool which will reprogram the computer system. For older components, there are other parts you can alter to change the timing. 2. Modify the Fuel Injection Pump. One of the more straightforward ways to convert the timing is to adjust the fuel injection pump. 1 Let your car cool down and disconnect the battery. The fuel injectors fire fuel into your engine’s cylinders, so you may start a fire if you remove them while your vehicle is running. Let the car cool off for 30-45 minutes if you were driving recently. Pop your hood and put some gloves on. Take out the inector hold down clamp bolt. The injector and clamp will rise out of the injector bore as the bolt is loosened. Check for damaged o-rings and copper combustion seal. The combustion seal is on the bottom of the injector. Lube up a new injector with clean oil, fit the old hold down clamp onto it, and install. x2wGTVg.
