Colorado Fuel Injectors
Choosing the correct Chevrolet Colorado fuel injectors depends on the year, make, model, engine, fuel system, emissions configuration, and OEM part number. This guide covers rebuilt genuine OEM injectors for select 2009 Colorado 5.3L V8 models and compatible 2015–2016 Colorado 2.5L and 3.6L gasoline direct-injection engines.
View the Chevrolet Colorado injector fitment guide
Chevrolet used significantly different fuel systems across the Colorado lineup. The 2009 5.3L V8 uses a set of eight conventional port fuel injectors, while the 2015–2016 2.5L four-cylinder and 3.6L V6 use high-pressure gasoline direct injection. These injector types are not interchangeable.
Precision Auto Injectors rebuilds genuine factory-original GM, Delphi, and Bosch injectors. Each complete set is professionally cleaned, tested, serviced, and flow matched before shipment.
Before ordering: Do not select injectors using the Colorado name or engine size alone. Confirm the model year, engine, emissions configuration, fuel system, electrical connector, and number printed on the original injector.
How to Find the Correct Fuel Injectors for Your Chevy Colorado
Start with the Year, Make, and Model search tool at the top of our website. Compare the recommended product with your original injector and complete vehicle information.
Verify all of the following before placing your order:
- Chevrolet Colorado model year
- 5.3L V8, 2.5L four-cylinder, or 3.6L V6 engine
- Port fuel injection or gasoline direct injection
- Federal, California, PZEV, or other emissions configuration where applicable
- OEM number printed on the original injector
- Bosch number, if present
- Electrical connector and physical injector design
- Quantity required: four, six, or eight injectors
The OEM number is the strongest confirmation. If the number cannot be read, provide the VIN and clear photographs of the injector body and connector before ordering.

Colorado Port Injectors vs. GDI Injectors
The 2009 Colorado 5.3L injector and the 2015–2016 Colorado GDI injectors operate in different types of fuel systems:
- Delphi 12580681: A conventional port injector that sprays fuel into the intake port before the intake valve.
- GM 12627093: A high-pressure direct injector that sprays fuel directly into the combustion chamber of the 2.5L engine.
- GM 12634126: A high-pressure direct injector designed for compatible 3.6L GDI applications.
GDI injectors operate under much higher pressure and use specialized seals and installation procedures. They must never be substituted with a port-style injector.
Important GDI Installation Considerations
Gasoline direct-injection systems can retain extremely high fuel pressure after the engine is turned off. Proper service procedures and suitable safety equipment are required. Installation should be completed by an experienced technician if the installer is not familiar with GM high-pressure fuel systems.
- Follow the correct GM service procedure for relieving fuel pressure
- Keep the injector bore, rail, and fuel connections completely clean
- Use the correct new seals and installation tools
- Do not reuse a damaged or incorrectly sized combustion-chamber seal
- Inspect the high-pressure rail and lines as directed by the service information
- Check carefully for leaks after installation
Symptoms of Failing Chevrolet Colorado Fuel Injectors
A clogged, leaking, electrically failing, carbon-restricted, or uneven injector may contribute to noticeable drivability problems:
- Rough or unstable idle
- Hard starting or extended cranking
- Hesitation during acceleration
- Loss of power under load
- Poor fuel economy
- Strong gasoline odor
- Random or cylinder-specific misfires
- P0201 through P0208 injector-circuit codes, depending on engine
- P0300 and cylinder-specific misfire codes
- P219A or P219B air-fuel imbalance codes
- Rich or lean fuel-trim codes
- Black exhaust smoke or fuel-contaminated engine oil
These symptoms can have more than one cause. Ignition components, intake leaks, fuel pressure, compression, wiring, sensors, and other systems may create similar problems. Proper diagnosis is recommended before replacing parts.
Why Flow Matching Matters
Every cylinder depends on its injector to deliver a consistent amount of fuel. A restricted injector can cause one cylinder to run lean or misfire. A leaking or excessive-flow injector may cause a rich cylinder, difficult starting, fuel odor, carbon buildup, or fuel dilution in the engine oil.
Testing the complete set makes it possible to compare injector performance under the same operating conditions. Precision Auto Injectors dynamically tests and flow matches each complete set to support balanced cylinder-to-cylinder fuel delivery.

Why Choose Genuine OEM Colorado Injectors?
Genuine GM, Delphi, and Bosch injectors were engineered for their approved fuel systems. Correct OEM injectors provide the intended dimensions, connector design, electrical behavior, opening response, fuel delivery, and spray pattern.
Low-cost replica injectors may look similar externally while using different internal components and calibration. Differences in coil quality, opening time, flow rate, or spray targeting can create drivability problems even when the injector physically fits. Rebuilt genuine OEM cores retain the factory injector design.

Will 12634126 injectors fit a 2017 or newer Colorado?
The product’s Colorado-specific application list covers 2015–2016 3.6L models. Do not extend that fitment to 2017 or newer trucks unless the VIN application and original injector number have been independently confirmed.
Will these products fit a diesel Colorado?
No. The products on this page are gasoline fuel injectors. They are not diesel injectors and should not be used in a Colorado equipped with a Duramax diesel engine.

No. GM 12627093 / Bosch 0261500106 is a set of four for compatible 2.5L engines. GM 12634126 is a set of six for compatible 3.6L V6 engines. Their engine applications and calibrations are different.
Do stock replacement Colorado injectors require tuning?
Factory-flow injectors normally do not require tuning when the original injector number and complete vehicle application match. Tuning may be required if a different injector, engine combination, fuel pressure, or fuel type is used.
Are these Chevrolet Colorado injectors new or rebuilt?
They are genuine OEM injector cores that have been professionally rebuilt, cleaned, tested, and flow matched. Review each product page for its exact specifications and included service components.
What should I send if I cannot identify my Colorado injectors?
