Do you have problems with your 2003 Dodge Ram with 5.9L Cummins Diesel diesel fuel pump?

How you can detect if your pump is going bad?

Primarily, does your diesel truck have one or more of these signs or symptoms? If the answer is ‘yes’, you could have an pump problem.

• Motor Won’t Crank – If your vehicle’s pump is not correctly feeding diesel to your fuel injection system, your engine will starve for diesel, and won’t crank or run.
• Engine Hard To Crank – If the engine’s diesel fuel pump is becoming weak, but hasn’t entirely stopped pumping, you might discover that it’s not sending the correct amount of diesel to the diesel engine during starting, causing a hard to start-up truck.
• Lessened Engine Power – There may be many possible issues that would produce reduced diesel engine horse power in your 2003 Dodge Ram with 5.9L Cummins Diesel – one such reason could be a failing fuel pump.  In the event that the pump is not working efficiently, it might not be sending the proper amount of diesel fuel to your engine to give your engine it’s optimal horsepower levels.  Since there are so many issues may be producing a decrease in power however, correct diagnosis of your issue is important.

What is the cause of pump issues in 2003 Dodge Ram with 5.9L Cummins Diesel Engines?

Sometimes pumps stop working properly, usually as a result of bad fuel . When this happens, the truck might suffer from poor power, difficulty cranking, or lack of ability to start.

These are usual reasons for fuel pump failure:

• Contaminants and/or bad diesel – Bad diesel pumps are often caused by bad diesel (contaminants in the fuel,) which can stop up the diesel fuel pump, causing them to fail.
• Failing Fuel Pressure Regulator (MRomp). The fuel pressure regulator is a small piece on the diesel fuel pump that occasionally fail. From time to time only the MROMP fuel pressure regulator fails, instead of the internal parts of the pump.  To determine if the Fuel Pressure Regulator is the source of the problem, you’ll need to carefully examine the Fuel Pressure Regulator to determine if it has metal flaking or any other contaminants (debris, non-fuel liquid, etc.) inside of it, or in the area close to where it screws in.  If so, there’s almost certainly a more significant issue that’s causing the Fuel Pressure Regulator to go bad, and you will likely need to replace the pump and clean your fuel system.
• Freeze plugs blown out. Occasionally the freeze plugs will blow out inside of the pump.  When this happens, this means you have serious damage within the diesel fuel pump. Pumps that have the freeze plugs blown out will definitely need to be completely replaced, and the old pump’s core is not any good, so it cannot be exchanged.
