8 Major 6.4 PowerStroke Problems and their Complete Solutions

We all know very well about the horror stories of the 6.4 Powerstroke common problems, and many users are a little nervous about its next model as well – The 6.4 Powerstroke.

Here is the following. We are going to discuss the 6.4 Powerstroke common issues and their solutions following by its maintenance tips.

Problem 1: The motor does not start


  • Check the fuel tank, fuel pipes up to the transfer pump, injection pump pipes, fuel filters, water decanters. Connect a container with fuel directly to the injection pump inlet to check. If the engine starts, keep collecting it in the pipes to the fuel tank until you find the point where the problem is.
  • The fuel transfer pump must give pressure when the engine starts between 0.7 and 1.4 Kg / cm2. At full load, it will give approx. 1.76 Kg / cm2 and at high speed in a vacuum of about 2.11 Kg / cm2. Check the pressure, if it is low replace the transfer pump.
  • Loose injection pump drive sprocket. Engine out of point. Tune up the engine.
  • Check all of the above and verify that fuel is reaching the injectors. If everything is correct, repair the injection pump and change the injectors.

Easy Maintenance Hacks for Avoiding 6.4 Powerstroke Common Problems

6.4 PowerStroke problems-powered cars could well be considered one of the first efforts in the industry to reduce polluting emissions.

And, at the same time, improve the efficiency of vehicles worldwide.

As well as this configuration requires less fuel to generate the blast, resulting in an extended range with a single tank.

Unfortunately, these engines can also become a real headache if they are not properly maintained and cared for since their operation makes them more sensitive than a traditional vehicle.

Therefore, they can fail more suddenly and your repairs are extensively expensive.

For this reason, today we have decided to give you these maintenance tips for the 6.4 Powerstroke engine.

So that you can surely keep your diesel car on the road for many more years, saving money and happily traveling to all your destinations.

01. Don’t Let the Fuel Tank Empty

How many times have you not managed to drive your car only with the reserve, according to you to save money, squeezing every last drop of fuel from your vehicle?

Although that is a questionable useful practice for a traditional gasoline vehicle, in the case of diesel cars can be synonymous with 6.4 Powerstroke common problems.

Unlike traditional gasoline, diesel can generate more dirt and pollutant residues. 

Literally, which accumulate in the bottom of the tank and, by letting the fuel level drop to this point, can become embedded and pass through the filter and reaching up to your cylinders and causing failures that could be irreparable.

02. Don’t Over-rev Your Engine

6.4 Powerstroke engines, as you may already know, are very different from gasoline engines in operation.

Therefore, one of the fundamental aspects of diesel driving is to take care of the engine revolutions, since these work at a slower speed, which can initially generate Powerstroke 6.4 problems.

As a general rule, do not exceed the revolutions recommended by the manufacturer when driving on any type of road, and do not drive below 2,000 rpm, as this forces the engine to keep it running, generating a lot of carbon in the EGR valve and reducing the useful life of the same.

03. Take Care of Your Fuel Filter

As we already mentioned before, diesel is a fuel that generates more waste and dirt in the tank.

So, another vital aspect is to take care of and change your filter constantly to avoid perforations and malfunctions that lead to major failures.

It is recommended that the fuel filter, in addition to being constantly cleaned, be changed at most every 38,000 miles.

Although, we strongly recommend that you review your car’s user manual to check the manufacturer’s recommendations.

04. Monitor Oil Levels

Oil is a vital liquid in internal combustion vehicles since it is in charge of ensuring proper functioning between the components, freeing them from friction, and thus avoiding overheating, cracks, and 6.4 Powerstroke injector problems that could kill your car.

Speaking specifically of diesel engines, these are even more sensitive to lack of oil.

So, for no reason let the levels be below the recommended because you could end up with your vehicle derailed in no time.

Periodically check the bayonet of your car and make sure to do it on a street with no slopes for a more accurate result.

Also, remember to obey the manufacturer’s recommendations on the type of oil you should use.

05. Be Careful when Refueling

This rule applies not only to diesel cars but to any model in general.

That is, if when you get to the gas station you find that a pipe is filling the tanks, it is the worst time to fill your tank, since the pressure of the pipe will flutter the fuel inside, lifting the dirt seats at the bottom.

If you find yourself in this situation, we recommend waiting at least an hour for all the dirt to settle again or, failing that, look for another gas station but far from that area, as this will avoid refueling at a newly supplied station.

06. Keep Your Car On

If you traveled by road in your diesel vehicle, you should always remember that when you reach your destination, you must leave the engine running for at least 1 minute at idle before turning it off.

If you do not do so, the oil stored in the turbine could burn, damaging in turn, the turbocharger, 6.4 Powerstroke issues which would have an extremely high repair cost, severely affecting your pocket.

07. Comply with Your Dealer’s Maintenance Plan

When you buy a vehicle regardless of its type of engine, the seller will design a specific scheduled maintenance plan for the type of vehicle you purchased.

So, in the case of diesel cars, it is extremely important to fully comply with these appointments as accurately as possible, as this will greatly extend the life of your car.

Always remember that these scheduled maintenances are in charge of replacing, checking, and discovering all the possible failures.

That your car could present, preventing future 6.4 Powerstroke injector problems, and extending the warranty of your vehicle for a longer time.


Hope these solutions and maintenance tips will make sure that these Powerstroke 6.4 problems will never happen again.
