What is the problem with the fuel pump on the 6.7 Ford?
The 6.7L Power Stroke diesel engine, used in Ford Super Duty trucks, is known for its power and reliability. However, like any complex engine, it has its share of potential issues. One of the most commonly reported problems is related to the fuel pump. In this article, we’ll explore the causes, symptoms, and solutions for fuel pump issues in the 6.7 Ford engine.
What Causes Fuel Pump Problems in the 6.7 Ford?
The 6.7 Ford engine is equipped with a high-pressure fuel pump, often referred to as the CP4 pump. While this pump is designed to deliver precise fuel pressure for optimal performance, it has been known to fail under certain conditions. Here are some common causes:
- Low-Quality Fuel: Contaminated or low-quality diesel fuel can cause excessive wear on the pump components.
- Water Contamination: Water in the fuel system can lead to corrosion and damage to the pump.
- Design Flaws: The CP4 pump has been criticized for its susceptibility to failure, especially when compared to its predecessor, the CP3 pump.
- Lack of Lubrication: Diesel fuel acts as a lubricant for the pump. If the fuel lacks sufficient lubrication properties, it can lead to premature wear.
Understanding these causes can help truck owners take preventive measures to avoid costly repairs.
Symptoms of a Failing Fuel Pump
Recognizing the early signs of a failing fuel pump can save you from a breakdown or more extensive engine damage. Here are the most common symptoms:
- Hard Starting: Difficulty starting the engine, especially in cold weather, can indicate fuel delivery issues.
- Loss of Power: A noticeable drop in engine performance, particularly under load or during acceleration.
- Check Engine Light: The engine control module may detect irregularities in fuel pressure and trigger a warning light.
- Metal Shavings in Fuel: A failing pump can shed metal particles, which may be visible in the fuel filter or tank.
- Engine Stalling: Sudden stalling while driving is a serious sign of fuel pump failure.
If you notice any of these symptoms, it’s crucial to address the issue promptly to prevent further damage to the engine.
How to Address Fuel Pump Issues
Dealing with a failing fuel pump can be costly, but there are steps you can take to mitigate the problem:
- Use High-Quality Diesel Fuel: Always fill up at reputable stations to reduce the risk of contamination.
- Install a Fuel Additive: Additives can improve lubrication and protect the pump from wear.
- Regular Maintenance: Replace the fuel filter at recommended intervals to keep the system clean.
- Upgrade the Pump: Some owners opt to replace the CP4 pump with a more robust CP3 pump to improve reliability.
- Inspect for Water Contamination: Use a water separator or regularly check for water in the fuel system.
By following these steps, you can extend the life of your fuel pump and avoid unexpected breakdowns.
Conclusion
The fuel pump in the 6.7 Ford engine is a critical component that requires proper care and attention. While issues with the CP4 pump are well-documented, understanding the causes and symptoms can help you take proactive measures to protect your vehicle. If you suspect a problem with your fuel pump, don’t hesitate to consult a trusted mechanic or auto repair shop for a thorough inspection and repair.

Frequently Asked Questions
What year 6.7 Power Stroke has CP4 problems?
The issue affects models from 2011 onward. Plaintiffs argue that Ford was aware of the defect but failed to take proper action, leaving truck owners with expensive repair costs. The lawsuit primarily targets Ford trucks with 6.7L Power Stroke diesel engines, particularly those from model years 2011 and later.
What is the biggest problem with 6.7 Power Stroke?
What are the most common problems with the 6.7 Powerstroke?
- Cold Side Charge Pipe Failure. The cold side charge pipe is a critical component that carries compressed air from the turbocharger to the intake manifold.
- CP4 Injection Pump Failure.
- Turbo Issues.
- Fuel Filter Housing Failure.
What is the recall on the 6.7 diesel?
Ford is no longer the most-recalled brand in America, but it didn't end 2024 quietly. On December 20, the automaker recalled 295,449 trucks equipped with the 6.7-liter diesel engine. A problem with fuel pumps in these vehicles could lead to reduced power or a stalled engine.
What is the root cause of the CP4 pump failure?
Fuel Contamination: The CP4 pump is exceptionally sensitive to fuel quality, susceptible to damage from contaminants like water, debris, or metal particles in the fuel system.
What year 6.7 Powerstroke has CP4 problems?
The issue affects models from 2011 onward. Plaintiffs argue that Ford was aware of the defect but failed to take proper action, leaving truck owners with expensive repair costs. The lawsuit primarily targets Ford trucks with 6.7L Power Stroke diesel engines, particularly those from model years 2011 and later.
What is the fuel pump problem with the 6.7 Power Stroke?
As many 6.7L Powerstroke owners have become painfully aware, the high pressure fuel pump (also known as a CP4 pump) has a design weakness. When the CP4 pump fails, it will shed tiny particles of metal throughout the entire high pressure fuel system, causing a number of serious 6.7 Powerstroke problems.
How much does it cost to fix a 6.7 Power Stroke CP4 failure?
Despite having to deal with being broken down on the side of the road, truck owners will be facing fuel system repairs that can easily exceed $10,000. The unreliable reputation is supported by recalls and lawsuits leveled at various auto manufacturers that use the CP4 in their production vehicles.
What is the recall on the 6.7 Power Stroke fuel filter?
U.S. authorities are looking into fuel leaks that can result in a fire on some 2015-2021 Ford Super Duty pickups. More specifically, affected models include F-250, F-350, F-450 and F-550 trucks equipped with the 6.7-litre Power Stroke turbo-diesel engine.
What year do Fords have CP4 problems?
The issue affects models from 2011 onward. Plaintiffs argue that Ford was aware of the defect but failed to take proper action, leaving truck owners with expensive repair costs. The lawsuit primarily targets Ford trucks with 6.7L Power Stroke diesel engines, particularly those from model years 2011 and later.
What is the recall on the Ford 6.7 high-pressure fuel pump?
Ford Motor Co. has recalled over 295,000 Super Duty F-series trucks for a condition where biodiesel deposits may form on the roller components of the high-pressure fuel pump and lead to pump failure, according to the National Highway Traffic Safety Administration.
