Question about 1988 Mercedes-Benz 190
MY 1988 MERCEDES 190D ON INCLINE WONT START. ITS LIKE IT IS NOT GETTING ANY FUEL.
Hello I'm an M.B. tech.. It sounds like the fuel strainer is clogged. It is a very common problem on M.B. diesel engines of that era. Diesel fuel develops algea inside the fuel tank and after a period of time it clos the strainer. The strainer is at the bottom of the fuel tank where the big fuel hose attatches to the tank. The hose unscrews frome the strainer and then the strainer unscrews from the tank. There is a filter on the strainer that can be cleaned and reinstalled. In the engine compartment there is a small primer pump that is by the fuel rack inline with the feed hose from the tank. If you turn the knob(clear or white plastic) on the pump it will retract allowing you to use it as a hand pump. If when attempting to retract hand pump it is sucked back down and will not stay retracted that means you have a restriction in the line- your fuel strainer is clogged is the most likley problem. replace both fuel filters during repair for best results. Good Luck
