Restored 1998 E Class diesel fails to start: Replacing multiple parts

Even though this old Mercedes W210 has a non-complicated NA diesel engine, I replaced all these parts just as a precautionary measure.

BHPian Vmax1200 recently shared this with other enthusiasts.

Last week, my day started with a frustrating twist – my car refused to start! Well, after ruling out the usual suspects, I did some quick research online and found that a malfunctioning fuel shut-off valve can prevent the fuel from reaching the engine. Luckily the “Merc Motors” in Cochin had it in stock and I got it replaced.

Even though OM605 is a non-complicated NA diesel, the parts which may prevent the engine from starting are the fuel shut-off valve, crankshaft position sensor, air in the system due to worn O rings and Diesel plunger spring. So, as a precautionary measure, I replaced it altogether with the fuel shut off valve. The V belt had a noise in the idle RPM. So, replaced the damper and spring. Now, the engine runs very smoothly at idle. Planning to fix new diesel injection nozzles too.
