One of my fuel injector burned out what’s wrong?
My fuel injector burned out what's wrong?
My car has 256344 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
If you are referring to the electrical solenoid within the injector, like any electrical part it can fail due to degradation of the insulation, wire breaks and so forth. The injector can be tested while still on the car and if indeed it has failed you can request fuel injector replacement and the responding certified mechanic will make all necessary repairs. If one injector is replaced, for best results in terms of cylinder balancing, the other three injectors should be removed from the fuel rail and sent a lab such as Mr. Injector for cleaning, replacement of the tiny internal filter baskets, and verification. Serving all the injectors and replacing the internal injector filters at the same time will promote a smooth running, more efficient engine and that helps to avoid future problems.

How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
If you have one or more faulty fuel injectors — due to wear or mechanical or electrical issues, driving for a long time can cause several problems: Stalling or failure for your car to start. Flooding of your engine. Pre-ignition of your fuel.
Engine Stalls or Rough Idle
Your car may sputter or shake, mostly during traffic stops. The engine idling is mainly due to inconsistent revolutions per minute (RPMs). A sudden decrease in fuel supply, especially during uphill climbing, may accompany rough idling.
Fuel injectors typically fail due to a buildup of contaminants such as carbon. Carbon build-up can cause a clogged or partially clogged injector, preventing the injector from closing all the way. This results in a drip that creates a misfire.
There are many reasons for faulty fuel injectors but the three most common issues are clogging in your car`s fuel injectors, leaky and dirty injectors. You should remove the fuel injectors and clean them up before putting them back in for your car to function optimally.
Although fuel injectors are individual, they are designed to work as part of a team with the other injectors. So, if you`re wondering if you can replace just one injector or all, the answer is almost always to replace them all. Typically, the labor to replace one or all of them is the same.
If they`re damaged from another failure in your engine but you just replace the injectors, the failure is likely to happen again. And you`ll be spending more on another set of injectors. Do You Need to Replace All Your Injectors? Many people want to just replace one injector when it fails instead of replacing them all.
The customer can look out for a deeper, gravely engine sound, engine chugging, the whole vehicle might have a slight shake or vibration.
Good quality fuel injectors rarely cause misfires whereas, poor quality or faulty injectors cause destructive misfires. The vehicle can experience various misfires when a faulty injector is a reason; it can lead to a loss in acceleration, power, and reduction in fuel efficiency.
When a fuel injector is clogged, it needs a concentrated cleaning to resolve the problem. This can be done by a qualified mechanic, or if you know your way around the inside of an engine, you can do it yourself. To start, invest in a fuel injector cleaning kit.
Common problems include stalling after you have pressed the accelerator, struggling to accelerate and poor fuel economy. Most of these problems occur due to inadequate air to fuel ratio. Also, any delay could lead to overheating and the engine could stall.
“Fuel injectors have an atomizing nozzle that distributes fuel evenly for optimal combustion and efficiency.” Now, a vehicle will typically have one fuel injector per cylinder, with a lifespan of between 50,000 and 100,000 miles, or about 80,000 and 160,000 kilometers.
The Engine Misfires
Dirty fuel injectors may cause your vehicle`s engine to misfire. This problem makes the motor feel as though it is sputtering — sending vibrations through the car. Such misfires can happen when a fuel injector problem mixes up the delicate balance between fuel and air entering the engine.
For high-horsepower engines, typically 2,500 hp and up, two fuel injectors should be used per cylinder, said Anthony Donnarumma. The primary injector operates at all times when the engine is running; the secondary turns on when the vehicle`s ECU detects that the primary injector has hit a duty-cycle threshold.
Multiple injectors are likely affected: In most cases (especially when contamination is involved) when one diesel injector goes out, the remaining injectors usually aren`t far behind. If, when diagnosing your injectors, you discover multiple injectors are damaged, it`s best to replace the entire set.

A malfunctioning injector, if not cleaned or replaced in a timely manner, can indeed result in engine damage. This is due to the fact that irregularities surrounding the atomization and timed delivery of fuel can result in cylinder pre-ignition.

ANSWER : The switch you are referring to is vended with the required electrical and fuel schematic (I just looked in the box) that answers your installation question. If you want an advance view, here is a link as well. Yes, you need a return line and just refer to the aforementioned link. If you are retrofitting back to OEM, I strongly encourage you to buy the original Factory Service Manual (FSM). There are lots of details attending this system and obviously it is difficult to recount it all here. The FSM will make your life much easier and you can then make sure your installation is perfect. Alternatively, YourMechanic can dispatch a certified mechanic and perform the whole retrofit and check out if you desire. Just request and schedule a generic service such as fuel pump service and the mechanic will come to your location and estimate the parts and labor required.

I have a truck that won’t run and is not getting gas to the engine. Fuel pump is running, have a new filter and new fuel pressure
ANSWER : Hi There,
It sounds like you may have a clogged fuel injector or potentially a faulty injector that is fried internally. I would suggest testing them if you have access to a multi meter. Disconnect the injector from the electrical connector and set your multi meter to Ohms mode and measure the resistance of the injector. After testing all injectors, compare the resistance. They should be the same or very close. If they are not, they will likely need to be replaced.

Just replaced my fuel pump but its not getting any power tested fuel pump relay and fuel fuse both good tested the wires all good.
ANSWER : You need to look at the theft light on dash to make sure it comes on and goes off when you turn the key to the on position. If light comes on and stays on then your theft system is causing the fuel pump to not be engaged. I recommend you check the theft system and then scan the computer for theft system codes. You may need to reprogram the keys to work or you have an bad sensor for the ignition key in the steering column.

Fuel pressure
ANSWER : Hello,
You may want to try checking the fuel pump relay. The relay wires should have ground on two wires, power on one wire and switched power on another wire. To activate the fuel pump your ECU actually connects one of the ground wires to complete the circuit and send power to the fuel pump. If the wires all have power running through them, then it is likely you have a faulty relay. The wire coming from the fuel pump is the other ground wire. I would recommend having an expert from YourMechanic come to your location to diagnose your wiring as this can be very difficult and time consuming without the proper wiring diagram.
