Symptoms of Failing Dodge Cummins Fuel Injectors

Think you're experiencing issues with your Dodge Cummins diesel engine fuel injectors? These symptoms could point to this problem:

  • Excessive Smoke
  • Power Loss
  • Rough Idle
  • Fuel in Oil
  • High Return Fuel
  • No Start

Excessive smoke and idling problems can indicate different issues in your engine, but one of the main things that could be going wrong is poor fuel filtration. This can be due to ball seat erosion, leading the injector to not seal properly. Since a correct seal is necessary for proper injector function, this damage means your injectors won't be functioning as they should.

Do any of these symptoms sound familiar? It might be time for some replacement fuel injectors for your Dodge Cummins engine. Check out our post on choosing the best common rail injectors for your diesel engine. 

 

What's Causing Your Dodge Cummins Fuel Injectors to Fail?

But what can you do to help keep your injectors operating like they should?

By knowing the some of the common causes of failure, you can work to prevent damage to your injectors. These causes include:

  • Quality of Diesel Fuel: The fuel you put into your engine can have a huge impact on its performance. Poor quality or contaminated fuel can lead to poor performing injectors. To avoid using contaminated fuel, try to fill up at places that move large amounts of fuel. This might mean passing by a cheaper option, but if the fuel has sat for a long period of time, it might be contaminated. 
  • Operating Conditions: Operating conditions also impact how your injectors will perform and can lead to failure. Some conditions that can cause problems for your injectors include: short runs, excessive idling, cool operating, and light engine loadings. These can lead to deposit problems in your combustion chamber, exhaust spaces, turbocharger, and DPF filter.
  • High Pressure/High Temperature: High pressure and high temperatures can cause fuel degradation. Similarly, they can cause deposits in pumps and injectors, lowering the lubricating ability of your fuel.
