Ford Diesel Fuel Pump Problems

Ford diesel engines are mostly consistent in performance. Power, Efficiency & Reliability of Ford Diesel Engines are vital parts of a Ford truck, especially on their diesel models.

As most complicated machine, Ford diesel engine fuel pump has some common problems. Ford diesel fuel pump problems can cause a variety of symptoms, from inconvenience to stranding.

These fuel pumps have proven to be problematic for hundreds ( and in some cases thousands) of Ford owners, causing major distress. 

Ford Diesel Engine Models That Have Fuel Pump Problems

While Ford has built more than a half-dozen diesel trucks over the decades, certain brands and even models are more likely to experience fuel pump woes. So far, several models (but not ours) have reported fuel pump issues:

Ford F-250 and 350 Super Duty (2011 to present): These trucks, outfitted with the 6.7-liter Power Stroke diesel engine, have also had issues with a failing fuel pump.

Ford F-150 (2018-present): In this list, even some new models with the 3.0L Power Stroke diesel engine have been found to goof fuel up their pumps.

Ford Transit (2015-present): Vans with the 3.2L Power Stroke diesel engine also have issues.

Fuel pump failures are more common in these models, especially those with high mileage or that are heavily used.

How To Identify Ford Diesel Fuel Pump Problems?

Determining if a fuel pump is broken will prevent you from surprise breakdowns and expensive repairs. Here are some warning signs:

Hard Starting: One of the very first symptoms a defective fuel pump will produce is difficulty starting.

Loss of Power: A noticeable loss of power, especially under load and while accelerating, may be a sign that your fuel pump is failing.

Engine Misfires: If the engine misfires at high RPMs or while idling, it could be related to your fuel pump.

Check Engine light: If the service engine or check engine lights come on, accompanying any of the symptoms above, act quickly and have an exhaust leak inspected.

Strange Sounds: Any whining or humming sounds coming from near the fuel tank are likely a sign that your winding-down pump is about to retire.

This is why, through regular maintenance and timely diagnosis, you can avoid severe damage from occurring in your vehicle for its constant reliability.

Common Ford Diesel Truck Fuel Pump Problems

Identifying normal Ford diesel problems helps you to spot as well as avert them earlier. Common Ford diesel truck problems are…

Fuel Contamination: Of course, the biggest risk from contaminated fuel is the potential to seriously destroy your vehicle’s fuel system, including its high-pressure components like injectors and HPFP.

Fuel Pump Wear and Tear: Inside the fuel pump, parts wear out over time, leading to poor performance or failure. This is particularly true for abused or high-mileage trucks.

Electrical Problems: Fuel pump failure, intermittent fuel, or no-start shutoff due to a bad wiring harness causing too much resistance in the system.

Fuel Pressure Issues: An erratic fuel pressure, most often caused by a failing pump, will translate to poor engine performance and increased fuel consumption.

Inadequate Fuel Supply: Fuel supply insufficiency occurs when the fuel pump supplying your engine simply cannot deliver enough juice for normal operations and increases power levels. This most often occurs when the fuel filter is clogged or when the pump goes bad.

Some of these problems can be avoided with routine maintenance, like changing the fuel filter and using quality diesel fuels. Also, if you know what to look for when it comes to symptoms and catch them early enough, this will prevent further damage from taking place, driving repair costs through the roof.

Ford Diesel Engine Fuel Pump Diagnosis

If you believe your Ford diesel truck has a fuel pump issue, getting the problem diagnosed as soon as possible is very important. Here are the steps involved:

Listen for Unusual Noises: A dwindling fuel pump typically whines or hums. If you hear sounds coming from the fuel tank area, it might be a problem.

Test Fuel Pressure: Check the fuel pressure by connecting a fuel pressure gauge to your car’s fuel system. This will be a low pressure, indicating the pump is going bad.

Check the Fuel Filter: A blocked fuel filter can be confused with a faulty pump. Check the filter: Inspect and replace it if necessary.

Test the Fuel Pump: If you have low fuel pressure and a clean filter, you or your suspect that the fuel pump may need testing/replacement. This will almost certainly require a professional diagnosis and repair.

Solutions for Ford Diesel Engine Fuel Pump Problems

But to avoid fuel pump problems, you need some of the following steps:-

Regular Maintenance: Routine maintenance, such as replacing the fuel filter and cleaning the fuel system, helps prevent fuel pump issues.

Use High-Quality Fuel: In high fuel conditions, clean and quality diesel is required; after quantity, this creates less chance of contamination and a year of life of the fuel pump.

Install a Fuel Additive: Many fuel additives are designed to clean the system and protect deposits from forming, which can greatly enhance overall performance.

Check Fuel System Components: Periodically inspect the vehicle’s fuel system, including the tank lines and filters, for damage.
