How much does it cost to fix a 6.7 powerstroke CP4 failure?
The 6.7 Powerstroke engine, a popular diesel engine used in Ford trucks, is known for its power and reliability. However, one of its weak points is the CP4 high-pressure fuel pump, which can fail and lead to costly repairs. In this article, we’ll break down the costs associated with fixing a CP4 failure and provide insights into why this issue occurs and how to prevent it.
What Is a CP4 Failure?
The CP4 fuel pump is responsible for delivering high-pressure fuel to the engine’s injectors. Unfortunately, this pump is prone to failure, especially when exposed to low-quality or contaminated fuel. When the CP4 pump fails, it can send metal shavings throughout the fuel system, causing extensive damage to components such as the fuel injectors, fuel rails, and fuel lines.
How Much Does It Cost to Fix a CP4 Failure?
Repairing a CP4 failure can be expensive due to the extensive damage it causes to the fuel system. Here’s a breakdown of the typical costs:
- Replacement of the CP4 Pump: The cost of a new CP4 pump ranges from $1,000 to $2,000, depending on the brand and quality.
- Fuel System Components: Replacing damaged fuel injectors, fuel rails, and fuel lines can add another $3,000 to $5,000 to the repair bill.
- Labor Costs: Labor charges for this repair typically range from $1,500 to $2,500, depending on the shop’s hourly rate and the complexity of the job.
In total, fixing a CP4 failure can cost anywhere from $5,500 to $10,000 or more. The exact cost will depend on the extent of the damage and the rates charged by your repair shop.
Why Does the CP4 Pump Fail?
The CP4 pump is designed to operate with ultra-low sulfur diesel (ULSD) fuel, which has lower lubricity compared to older diesel fuels. This reduced lubricity can cause excessive wear on the pump’s internal components, leading to failure. Additionally, contaminated fuel or water in the fuel system can accelerate the wear and tear on the pump.
How to Prevent CP4 Failures
While CP4 failures can be costly, there are steps you can take to reduce the risk:
- Use High-Quality Fuel: Always fill up with high-quality diesel fuel from reputable stations to minimize the risk of contamination.
- Install a Fuel Additive: Diesel fuel additives can improve lubricity and protect the CP4 pump from excessive wear.
- Regular Maintenance: Replace fuel filters regularly and ensure your fuel system is free of water and debris.
- Consider a CP4 to CP3 Conversion: Some owners opt to replace the CP4 pump with a CP3 pump, which is more reliable and less prone to failure.

Frequently Asked Questions
How much does it cost to replace an injector on a 6.7 Power Stroke?
Labor costs are estimated between $190 and $240 while parts are priced between $664 and $770.
How long does the 6.7 Power Stroke last?
200,000 to 300,000 miles
How Long Will It Last? With proper care, many truck owners report that their deleted 6.7 Powerstroke engines last 200,000 to 300,000 miles or more. However, neglecting maintenance or using poor-quality delete kits can shorten the engine's lifespan.
What years to avoid 6.7 Power Stroke?
But if you're in the market for a 6.7-liter Power Stroke and you want to avoid developing pesky maintenance issues or paying for repairs, your best bet is to search for a 2015 or newer model and avoid model years 2011 through 2014.
How much is the settlement for the CP4 lawsuit?
$35 million settlement announced for Chevy, GMC truck owners
According to JND Legal Administration, a proposed settlement has been reached in a class action lawsuit against General Motors in regards to a defective high-pressure fuel injection pump known as the “CP4.”
What are the symptoms of a CP4 pump failure on a 6.7 Power Stroke?
Our actual fuel rail pressure is the data point to watch, start by cranking the truck and watch this number, if the Actual Pressure is somewhere around 350-500psi this is the first sign you have a high-pressure CP4 Fuel Pump Failure.
What is the life expectancy of a 6.7 Power Stroke CP4?
between 200,000 and 300,000 miles
The Ford 6.7L Powerstroke diesel engine is known for its durability and can last between 200,000 and 300,000 miles on average. However, with consistent and proper maintenance, this engine can reach 400,000 miles or more, making it a reliable choice for many truck owners.
What happens when a CP4 goes bad?
Difficult Starting: Difficulty initiating the engine, particularly when cold, may signal CP4 pump failure, resulting in inadequate fuel pressure to the injectors. Engine Misfires: Inconsistent fuel delivery due to CP4 pump failure can lead to engine misfires, rough idling, or hesitation during acceleration.
How many miles will a CP4 pump last?
Air in the pump means that metal rubs against metal, causing accelerated wear. This will eventually cause the CP4 to fail, often around 100,000 miles. Before it fails, metal shavings are produced by the CP4, which travel into the fuel injectors and the fuel lines with catastrophic results.
How much does it cost to replace the injection pump on a 6.7 Power Stroke?
Labor costs are estimated between $517 and $653 while parts are priced between $1,409 and $1,594.
What happens when CP4 goes out?
Difficult Starting: Difficulty initiating the engine, particularly when cold, may signal CP4 pump failure, resulting in inadequate fuel pressure to the injectors. Engine Misfires: Inconsistent fuel delivery due to CP4 pump failure can lead to engine misfires, rough idling, or hesitation during acceleration.
