subject: Fuel Filter Troubleshooting - Automotive Troubleshooting Secrets [print this page] As fuel enters the engine, it goes through a filter that takes out debris and dirt from the fuel. When a problem occurs with this filter, numerous engine problems occur. You need to know fuel filter troubleshooting to fix these problems. Below are engine problems that you need to know to point out if you have a problem in your fuel filter.
An engine that hesitates to run properly simply means that you have fuel filter problems. It may be that it is clogged with tons of dirt and other particles. It obstructs the normal flow of fuel to the car's engine causing it to seemingly stall for a brief moment. Another sign of a fuel filter problem is when your engine is running roughly. It happens when the engine combustion is not in a normal state. This is caused by worn out or clogged filter. A defective fuel filter can even cause your vehicle not to start. This is the result when the filter is fully obstructed with dirt and thereby completely depleting the engine of fuel.
When your vehicle runs smoothly at high speed but begin to hesitate when running slow is also an indication that your fuel filter is dirty or needs changing. High pressure in the fuel flow while running at high speed can force fuel through the congested filter. But when running slow and fuel flow pressure is low, there will be no sufficient force to allow fuel to get pass the dirty filter.
Another annoying problem that will definitely force you to know fuel filter troubleshooting is when your vehicle frequently dies out while you are driving. When fuel flow shifts from flowing adequately to being flowing irregularly, it causes the engine to be erratic and completely die out later on.
It is important that you have knowledge about fuel filter troubleshooting. Now you don't have to scratch your head and wonder every time your vehicle starts running poorly.
