What are the reasons for the high-pressure oil pump of a diesel engine not delivering oil?
1 Answers
There are several reasons why the high-pressure oil pump of a diesel engine may not deliver oil: 1. Dirty diesel filter: It should be noted that there are three diesel filters. One is located where the oil pipe connects from the fuel tank. There are two more near the fuel tank, on the engine, specifically on the inlet oil pipe. 2. Dirty main pump: The main pump must be calibrated. First, inspect the fuel system to check if the oil path is dirty or clogged. It is best to test whether the fuel pressure is within the standard range. Additionally, check the atomization state of the injectors for any dripping, and inspect the throttle valve for carbon buildup. A dirty throttle valve can also cause poor acceleration. 3. Ignition system: Also, inspect the ignition system for any electrical leakage, and check the intake system for dirt, clogging, or air leaks.
