Why Do Diesel Fuel Injection Systems in Corpus Christi, TX Fail?

August 9, 2018 Published by Leave your thoughts

They say all good things must come to an end. Is this why fuel injection systems in Corpus Christi, TX eventually fail? The issue is probably more mechanical than metaphorical. If your fuel injector goes bad, it’s typically due to one of several common issues.

The pros at your fuel injection shop in Corpus Christi, TX offer the following guide to assist you with your fuel injection issues. Often, proper maintenance will allow you to avoid fuel injection failure. Here’s the scoop.

Debris

One of the main reasons fuel injectors fail is due to debris. Dust, dirt, rust, water or other particles make their way into the system and plug up the fuel injector parts. To protect your fuel injection system in Corpus Christi, TX from debris, take the following precautions:

  • Refueling: Avoid filling up from a brand-new shipment of fuel, as impurities haven’t had time to settle in the tanks. Additionally, purchase only high-quality fuel from trusted stations.
  • Filters: Change your fuel filters regularly to keep your system clean. Don’t use components that aren’t designed for your vehicle.
  • Storage: If your truck won’t be used for an extended period of time, turn on the engine occasionally to keep the system clear. This will help prevent corrosion.

Leakage/Flow

Another common reason for failure of fuel injection systems in Corpus Christi, TX is internal leakage or return flow. If your engine is hard to start or you experience low common-rail pressure codes, this is probably the issue.

The potential causes for this problem include leaking cross feed tubes, a cracked nozzle body, incorrect nozzle needle clearance and a worn injector ball seat.

To prevent this issue, keep your fuel system clean and avoid using aftermarket components. Also avoid overly aggressive turning. Lastly, don’t mix nozzle needles.

Excessive Injection

If you experience banging noises, smoke while idling or high exhaust gas temperature, your system may be failing due to excessive injection. This can be caused by a worn nozzle needle seat, a worn ball seat, debris in the system or a cracked nozzle.

To prevent this problem, replace worn injectors and worn nozzles. Keep your fuel system clean, replacing filters regularly. Use only manufacturer recommended parts.

Incorrect Injection

Your fuel injection system in Corpus Christi, TX may also fail if the injection rate is incorrect. If you experience poor cylinder balance or the vehicle is running roughly, this is probably the issue. Another red flag is large exhaust temperature variation.

Incorrect injection can be caused by poor nozzle flow balance, a partially clogged nozzle or wire-brushed nozzles. To prevent this failure issue, do not clean nozzles with a wire brush. It’s also important to keep your fuel system cleaned and filled with reliable fuel from trusted sources and use only properly designed components.
