How much does it cost to replace a failed injector?

A diagnosis of a “failed” injector can cost thousands of dollars in replacement costs. However, a closer look at the problem reveals an interesting insight. Since the introduction of the 7.3 L Power Stroke in 1994, injectors have been relying on oil pressure to fire the piston via the HEUI fuel system.

What happens if the fuel injector is not working?

Fuel injectors are a vital part of a complex fuel management system. Furthermore, New technology has made fuel injectors more precise than ever in dispensing fuel. If the fuel injectors are not operating properly, then other parts of the engine will be affected as well.

How to change your injectors in powerstroke 7.3?

What happens to the fuel injector in a Yanmar Diesel?

Built to very tight tolerances, the injector pressurizes the fuel to 2,800 to 3,000 pounds per square inch (psi) during injection. High engine hours can wear the injector and reduce output pressure. Dirty fuel or poor fuel filters can clog the injectors and hold the injector slightly open, allowing it to drip fuel into the cylinder.

What causes a fuel injector to stop working?

Over time the nozzle of the injector can become dirty and partially blocked. When you shut off your engine the injector will, soak up the heat of the engine. This causes any fuel left in the injector to evaporate, leaving behind hard deposits, inside the injector. Over time, these will eventually block the injector.

What is the code for a fuel injector failure?

If you are using a generic (not vehicle manufacturer specific) code reader; then you can expect to see codes beginning with P02. For example, a fault with an injector in cylinder one would give a code of P0201.

What to do if you have a spark plug misfire?

I suggest first removing and checking the spark plug and swap in a new one or swap with cylinder next to it. This way the misfire moves to other cylinder then you know it was plug and replace it. If misfire still on number one then check for spark and injector pulse and replace injector or coil as needed.

Can a clogged fuel injector be repaired quickly?

Clogged injectors can usually be repaired, if you catch the problem quickly. Sometimes a fuel injector is completely clogged, because of years of neglect or a lack of regular engine servicing. If this is the case then a refurbished replacement, may be the only option.

Why does my fuel injector keep misfiring?

It was only occurring after the engine had warmed up. Initial startup and driving in the morning would run fine and then later on in the day it would start misfiring, check engine light would come on and the engine would be surging. Turns out when the bad fuel injectors get warmed up this will occur.

What causes a fuel injector to leak over the engine?

So, the most common cause of leaky injectors is; the failure of the O-ring, where the injector meets the fuel rail. The O-ring can become, hard and brittle, from the heat of the engine. If it breaks, then fuel can leak out, over the engine. The other way an injector will leak is if, the injector body or nozzle cracks.

What do I need to do to disable Active Fuel Management?

Plus, you’ll also have to reprogram the ECM with AFM delete software. In addition to working on the top of the engine, you should also remove the oil pan and plug the pressure relief valve in the oil pan.

Where is the oil deflector valve on a GMC ACM?

This valve is located on the oil pan rail and prevents excessive oil pressure from negatively impacting the AFM components. The original version sprayed oil on the cylinder walls and increased oil consumption. In 2010, GM added a deflector (p/n) NAL-12639759 to redirect in into the pan.

Why does my Silverado lifter burn so much oil?

Engines with AFM use a high-volume oil pump. When you eliminate the AFM system, the extra oil is no longer needed. Excess oil will be pushed out of the pressure relief valve into the oil pan. This will spray oil on the bottom of the cylinder walls which can cause oil burning, especially in high-rpm engines.

What should I do before replacing fuel injectors?

Before installing the new fuel injectors, dip the fuel injector tip (sprayer end) into a small amount of engine oil. This will wet the seals, preventing leaks. If your new injectors came without seals, purchase new injector seals separately rather than reusing the old ones.

How to remove those pesky Ford fuel lines?

The quick disconnect lines for Ford (and some Chrysler) models can be difficult to get off. This guide will show you how to remove and reattach fuel lines. Please be careful when working with any kind of fuel system, wear gloves/safety goggles and keep sparks away! Loading…

How do you check for fuel injector leaks?

Turn the key to the on position and wait 10 seconds before turning to engine start. This will allow the fuel pump to refill the lines and fuel rails before the engine cranks. After the engine drops to the normal idle RPM, turn the engine off. Take a flashlight and check all the injectors for fuel leaks.
