In this article, you will learn about major Ford 7.3 Gas problems and their causes. Apart from that, this article will also explain five major fixes that will help you limit these problems’ adverse effects. Hence, to learn more, read on to the end of the article.
Are You Having Ford 7.3 Gas Problems?
The Ford 7.3 Gas engine came out in late 2019 and quickly became one of the major powerhouse motors. For instance, if you are looking for a heavy-duty truck, this engine can be a great economic alternative to a 6.7L Power Stroke engine that runs on diesel. Apart from that, it is also famous for its torque, reliability, and durability.
Hence, people who liked the Ford Super Duty series, were hopeful for the Ford 7.3 Gas engine. They wanted to enjoy a gas engine’s convenience along with the power and torque of diesel engines.
Although the Ford 7.3 Gas engine has major conveniences, it is less durable and resilient than the 6.7L Power Stroke engine.
However, not everything is bad about the Ford 7.3 Gas engine. For instance, with newer designs, people experienced more frequent problems than the older ones.
Ford 7.3 Gas Problems and Their Causes
The following are the major Ford 7.3 Gas problems and their major causes:
1. Wiring Harness Failures
To manage and maintain the electrical systems of the Ford 7.3 Gas engine and to maintain engine performance, the wiring harness is crucial. However, it repeatedly fails in the engine and causes multiple electrical malfunctions. This, further, has an impact on the overall function of the engine.
Basically, the wiring harness connects most of the electrical systems inside the engine. This ensures the effective distribution of the signals and the engine’s power on all parts.
However, with time, you can see the deterioration of the wiring harness. This happens due to excess vibration, heat, and environmental exposure. In fact, such a change happens due to manufacturing defects, assembly errors, and the use of poor-quality materials.
2. Issues in Transmission
The Ford 7.3 Gas engine comes with a 10-speed TorqShift transmission that is quite heavy-duty. Hence, it experiences rough shifting, and shift failures can become common after some time. These happen due to a complex transmission design.
The TorqShift transmission leads to various calibration and synchronization challenges. Apart from that, there are various software glitches that disrupt smooth shifts. Moreover, you can also face normal wear and tear with time. This causes the internal components to degrade with time. As a result, there are issues with transmission performance.
Hence, when you notice jerks or delays during gear changes, it means there are transmission issues. Additionally, you can experience difficulties with shifting, or a particular gear can feel stuck.
3. Cylinder Scoring
When the inner walls of the engine cylinders face damage, cylinder scoring happens. This leads to a lack of engine performance and higher oil consumption. Generally, such a thing happens due to poor lubrication, engine oil contaminants, and manufacturing defects.
Due to poor lubrication, it leads to degradation of engine oil. Hence, it causes metal-to-metal contact and cylinder scoring. Apart from that, manufacturing defects can lead to weaknesses and inconsistencies in cylinder walls. Hence, they become more susceptible to damage.
A reduction in engine performance is the first sign of cylinder scoring. Also, you will notice an increase in oil consumption and excessing blue-gray smoke from the exhaust. Furthermore, the engine can also produce knocking and tapping noises.
4. Issues During Starting
The Ford 7.3 Gas engine experiences starting issues as well. This happens due to problems with the fuel system or the ignition system. For instance, you can face difficulties in starting the engine. Moreover, it might not run smoothly after starting.
These problems are present due to problems with the fuel pump, fuel filter, and fuel injector. As a result, these components fail to supply the right amount of fuel, which makes it difficult for the engine to start. Hence, it performs poorly.
Additionally, there are ignition problems due to malfunctioning ignition coils, spark plugs, or issues with ignition control modules. Hence, there are difficulties in starting the engine. Apart from that, there are battery issues, like a weak battery.
5. Poor Performance in Mileage
With the Ford 7.3 Gas engine, you can experience a lack of fuel efficiency. This is because the company prioritized power over economy when it designed the engine. As a result, you can face fuel expenses and need to fuel your engine frequently.
Generally, the Ford 7.3 Gas engine delivers high power and torque. This leads to less fuel efficiency. Moreover, if your vehicle faces rapid acceleration and aggressive driving, fuel economy lowers even more.
Furthermore, there are maintenance problems with the engine. For example, you can see dirty air filters, low tire pressure, and worn-out spark plugs. As a result, there is less fuel efficiency.
Top 5 Fixes of Ford 7.3 Gas Problems
The following are some of the major fixes of all the above Ford 7.3 Gas problems:
1. Inspect the Harness
To deal with the wireless harness, you have to inspect the harness for damage signs and wear. Moreover, if you find any problems, you will be able to replace them with proper electrical connections. The best way to do it is to take it to an expert mechanic.
2. Do Regular Maintenance
By adhering to a regular maintenance schedule, you can address transmission problems. For instance, you can perform checks and replace the transmission fluid from time to time. Moreover, you also need to ensure that your transmission control module software is up to date.
However, if your problems are severe in nature, you need to do the necessary repairs. In some cases, you might even need to replace the transmission for proper functioning
3. Inspect the Cylinders
If you want to deal with cylinder scoring, you have to inspect your cylinders for damages thoroughly. First, get an idea of the scoring level, as it will give you an idea of how much you want to repair. For instance, you might need to repair the cylinder walls, smooth out minor damages, or replace components.
Moreover, you need to use high-quality filters to keep your engine oils clean. Moreover, you have to remove other debris to prevent further damage.
4. Addressing Issues with Starting
If you want to resolve the starting issue, you have to maintain your fuel system. Start by checking and replacing your fuel filter and injector with time. Apart from that, inspect and maintain the fuel pump.
Additionally, you need to examine the ignition system and check ignition coils, faulty spark plugs, and the ignition control module. Moreover, you also need to ensure that the battery is always charged. Also, replace it if it gets old. Furthermore, you can also consider replacing the starter motor if it is functioning properly.
5. Fixing Poor Gas Mileage
If you want to enhance fuel efficiency in your Ford 7.3 Gas engine, you have to ensure fuel-efficient driving practices. For instance, you have to accelerate smoothly and ensure the vehicle always runs at a consistent speed.
Apart from that, it is also important to maintain the engine and the car regularly. Here, you need to change the air filter and spark plugs and inflate your tires. Moreover, you must also ensure that there is no unnecessary weight on the vehicle, as it puts more pressure on the engine.
