what does it cost to replace fuel injectors on 2006 duramax
A fuel injector is essentially a solenoid with a fuel supply and a spray nozzle. Information technology is connected to a fuel track, and when the solenoid is energized a valve opens assuasive fuel to laissez passer through the nozzle end. The fuel injector is supplied with fuel pressure from the track and the ECM (electronic command module) controls the electrical signal to the injector; opening it for a specific amount of fourth dimension and injecting the proper amount of fuel into the cylinder.
There are three principal kinds of gas-engine fuel injector:
TBI, or throttle body injector – This is the simplest and oldest set-up, where a single injector sits in the throttle body and supplies the fuel for the engine. It's fairly easy to diagnose and replace.
Multiport fuel injector – It merely means there'southward a separate injector for each cylinder. This is by far the nigh common prepare-upwardly, with some advantages in efficiency over the older TBI organisation.
Straight injection – This uses a single injector for each cylinder, but instead of spraying into the intake organization they inject fuel directly into the combustion chamber. This is slightly more efficient, and is becoming more common. Disadvantages are that the intake valves don't stay as clean without fuel spray, and the injectors themselves are subject to the pressures and conditions of the combustion chamber.
What Does It Toll To Repair a Fuel Injection System?
The average cost to supplant a fuel injector on virtually vehicles, which is i of the more common repair needs, would exist about $140, excluding diagnosis.
Diagnosis is usually an hour of labor, though if an injector fails electrically and triggers a code the diagnosis of that is about as uncomplicated as they come, and many shops would fold that into the replacement labor.
Because fuel injection is a circuitous system, the costs associated with a repair can vary fairly widely. Hither are a few more specific examples of the fuel injector replacement cost on common vehicles in order to get a improve understanding of what is involved in a repair (using an boilerplate shop rate of $eighty per hour as a baseline).
1. A 2014 Dodge Journey 3.6L has a bank check engine low-cal and a misfire. The technician gets code P0304 for a cylinder 4 misfire. After diagnosing, they find that the cylinder four injector wiring is open up.
- Diagnosis – 1.0hr at $80/60 minutes, $lxxx
- Wiring repair – 0.5hrs at $fourscore/60 minutes, $40
- Total price of repair – $120
2. A 2012 Ford Focus 2.0L has a cheque engine light and a misfire. The technician pulls codes and diagnoses an open in the cylinder two fuel injector.
- Diagnosis – 1.0hr at $80/hr, $80
- Remove and replace straight injector – 1.1hrs at $80/hr, $88
- Fuel injector – approx. $85
- Full price of repair – $253
three. A 2008 Chevrolet Cobalt 2.2L has an intermittent rough idle with a cheque engine lite. The technician diagnoses injectors sticking and recommends an injector cleaning.
- Diagnosis – 1.0hr at $eighty/hr, $80
- Injector cleaning – 0.9hrs at $80/hour, $72
- Injector cleaner – approx. $l
- Full cost of repair – $202
4. A 2015 Audi A4 2.0L runs rough and lacks ability. The technician diagnoses the high-pressure fuel pump as failed.
- Diagnosis – 1.0hr at $80/hr, $80
- Remove and replace pump – 0.9hrs at $eighty/hour, $72
- Fuel pump – approx. $310
- Full cost of repair – $452
As nosotros come across, the cost to replace fuel injectors can vary adequately widely depending on what type of repair is needed which can exist anywhere from $10 to $200 for a uncomplicated electric repair or injection cleaning service, and it tin run much college if more parts and diagnosis are involved.
What Can Become Wrong With Fuel Injection Systems?
Fuel injection systems can fail in two master means – either a mechanical or electric failure.
Mechanical failures of the injection organisation differ depending on the blazon of arrangement in the vehicle. For multiport injection, it can include leaking or sticking injectors, fuel pressure regulators, injector seal leaks, also equally clogged spray ports. For direct injection, it includes faulty injectors, high-pressure fuel pumps, leaks, or internal engine harm.
Electrical failures affect the solenoid side of the injector, and they can be caused past a failed solenoid winding, bad connection, faulty wiring or a bad ECM. On a modern vehicle this will set a code and plough on the engine light, and so diagnosis follows the specific code. The circuits involved are relatively uncomplicated, and diagnostics are straightforward well-nigh of the time.
How Can You Avoid Fuel Injection Repairs?
Many manufacturers recommend an intake organisation cleaning on a 15,000 to 30,000-mile interval. This runs cleaning additives through the intake system and the fuel system, and (at least in theory) keeps the injectors in skilful shape. The gas additive cleaner is the more important thing for cleaning injectors and maintaining a skillful spray pattern, and information technology tin be done simply and cheaply with products widely available to consumers.
FAQ
Can you lot drive with a bad fuel injector?
Aye, only it's a bad idea. A misfire is usually caused, and that either puts the engine into limp way, or circulates raw fuel into the exhaust where it can damage the catalytic converter.
Will a bad injector throw a code?
Yes. Whether the failure is on the electrical side or the fuel side it would cause a misfire which the ECM would detect, setting a lawmaking and turning on the check engine calorie-free.
How long does a fuel injector last?
There is no predictable service interval or expected lifespan, and so injectors are ordinarily simply replaced when they have failed.
