Even though diesel engines are built to last for many miles, there may come a time when you feel your diesel vehicle isn’t performing as it should and is showing signs of potential trouble. You may be wondering how do you diagnose a diesel engine problem? It is important that you find a mechanic who understands diesel engines and can make a sound diagnosis in order to make the right diesel repairs.

Some common repairs are easy to diagnose, but there are some issues that are a little more difficult. Owners of diesel vehicles may think that because diesel engines are now computer-controlled, the technician should be able to hook up a scan tool to analyze data to pinpoint problems. And this is true in many cases.

But some problems may be tougher to diagnose than others, such as an injector issue. Even though they are electronic, sometimes the mechanical components inside the injector become worn, ceases to function properly, and then fails, resulting in an engine that stalls or won’t start.

There are several other issues that are related to damaged fuel injectors:

  • Bad Fuel Injectors: These could become faulty due to back leakage or overflow of diesel fuel as a result of worn or damaged car components.
  • Problem with the high-pressure pump: The fuel in the tank may be unable to ignite in the engine. This could be due to poor fuel injection caused by incorrect fuel pump functioning, a cracked fuel pump, or damaged injectors.
  • Dirty fuel filter: If the filter is clogged with dirt and fuel can’t pass through the tank, it will probably choke the engine and will not be able to run further.
  • Blocked air filter: This prevents sufficient air from reaching the engine for fuel combustion. Without this, there’s no powering of a diesel engine. Cracks in the supply line will also prevent combustion from occurring.
  • A flat battery: A drained battery will make it hard for the fuel pump to generate sufficient pressure for combustion.
  • Compression problems: The engine requires heat to ignite the fuel. Low engine compression affects the generation of heat, thereby causing a cascade of issues that ultimately results in an engine that won’t start.

Pro tip: Be sure to enlist the help of a professional diesel technician for even the simplest of diesel repairs, requiring expertise and specific equipment.
