Fuel Injection System Issues Can Really Turn On the Pressure

Weakened fuel pressure can often be a problem you don’t immediately detect in your car. In fact, your car may be suffering from minor fuel pressure issues without you even being aware of it. Electrical issues and contamination of the fuel are the two major causes of problems with pressure but a faulty fuel pump could also be the culprit. If you feel like you might be experiencing issues with your fuel injection system, it’s often best to bring your car into a professional auto garage. The vast amount of variables to consider during pressure tests could easily fill a book. However, it’s a good idea to have a basic understanding of the problems that could plague your fuel pump and possibly mention a pressure test on your next tune-up.

Keeping Your Fuel Pump Clean and Pristine

This is definitely not something you want to pull out of your fuel tank.

A quick glance at your vehicle’s owner manual should clue you in as to whether you’re due for a new fuel filter. You don’t remember when you last replaced the fuel filter? Bring it up to your local mechanic, because you don’t want to take unnecessary risks where your pressure is concerned. If the fuel filter has become excessively dirty or clogged, it can put unnecessary stress on the fuel pump which in turn could fry crucial wires and connectors. Then, instead of replacing the filter, you’ll wind up replacing the pump as well.

It can be a frustrating experience trying to keep your car looking pristine in Southern California thanks to the overwhelming, ever-present dust in the air. But the dust could be doing worse to your car than making your trips to the car wash more frequent. Dusty areas are notorious for wearing out fuel filters much more quickly than estimated by the manufacturer.

Gasoline Quality and Your Fuel Injection System

The fuel injector itself is prone to clogs as well. In fact, a mere 8% restriction has been enough to result in an engine misfire. How can something like this be prevented? Take note of the quality of gasoline you’re pumping into your car. A certain amount of detergent is added into gasoline to prevent the collection of waxy residue that clogs fuel injectors. Not all gasoline adheres to the high standard necessary to prevent this buildup, so don’t hesitate to choose a reliable brand over saving a few dollars at the pump.

Stay Up on Your Electrical System

Find your car’s harness plugs and inspect them if you feel an electrical failure is hurting your fuel injection system.

An electrical failure can wreak havoc on your fuel injection system. If you know the location of the harness plugs, inspect them for any residue or signs of burning. You can also have your mechanic give it a look if you’re not sure where the harness plugs are located in your car. Your mechanic can run a voltage drop test specifically geared to the portion of your electrical system relevant to your fuel pump. Prolonged use of damaged wiring will result in the death of your pump, so it’s not a bad idea to stay aware of the state of your electrical system.

Replacing Your Pump

In the event that your fuel pump does require replacement due to compromised fuel pressure, your mechanic will also give your fuel tank a good cleaning. A clean tank is crucial in ensuring that the fuel strainer and pump function at their optimum. The strainer will be replaced as well as a strainer is not reusable once the pump has failed.

Adequate fuel pressure is arguably the most important component of your car’s fuel injection system. Check your car’s owner manual to confirm when you’re due for a replacement and keep in mind that due date can be moved up if you’re driving in dry, dusty climes and jolting metropolitan areas. Stating on top of your fuel injection system, like so many sensitive mechanical processes in the auto world, could save you a small fortune.
