Diesel Injector Testing and Repair in Pueblo, Colorado
At Divine Fleet & Auto Repair, we specialize in diesel injector testing, cleaning, and repair services to restore your engine’s fuel efficiency, power, and reliability. Diesel fuel injectors play a crucial role in delivering the right amount of fuel into the combustion chamber at precise intervals. Over time, injectors can become clogged, worn, or damaged, leading to poor engine performance, excessive fuel consumption, and rough idling.
Whether your diesel truck is misfiring, producing excessive smoke, or struggling with fuel economy, our expert diesel mechanics can diagnose and repair faulty fuel injectors, ensuring your engine runs smoothly.
Professional Fuel Injector Services for All Diesel Engines
Signs of Failing Diesel Injectors
Faulty diesel fuel injectors can lead to major engine problems if left unchecked. Some common symptoms include:
Rough Idle & Hard Starting – Fuel injectors that are clogged or leaking may cause engine misfires or difficulty starting.
Excessive Smoke from Exhaust – White smoke may indicate leaking injectors, while black smoke suggests over-fueling or poor atomization.
Loss of Power & Poor Throttle Response – Dirty or worn injectors reduce fuel delivery, leading to sluggish acceleration and lower performance.
Decreased Fuel Economy – If your MPG has dropped, your injectors could be leaking fuel or spraying inefficiently.
Knocking or Unusual Engine Noises – A failing injector can cause an uneven fuel burn, leading to pre-detonation and knocking sounds.
Fuel Smell in the Engine Bay – A leaking injector may cause raw diesel fumes to enter the engine bay, posing safety and performance risks.
If your truck exhibits any of these issues, bring it to Divine Fleet & Auto Repair for a comprehensive injector test and repair.

1. Comprehensive Injector Diagnostics
Before replacing any injectors, we perform a thorough evaluation using:
-
Snap-on Zeus Scanners & Snap-on Pro Link – Advanced diagnostics to detect injector misfires, fuel pressure variations, and trouble codes.
-
HP Tuners Platform (for data logging) – Allows us to monitor fuel delivery and injector pulse width in real-time.
-
Injector Flow Testing – Measures fuel spray patterns, atomization quality, and delivery rates.
-
Leak-Down Testing – Detects fuel leaks and pressure loss from faulty injectors.
By accurately diagnosing the problem, we eliminate unnecessary part replacements and ensure cost-effective repairs.
2. Professional Diesel Injector Cleaning
If the injectors are clogged but still functional, we perform a deep cleaning using ultrasonic technology and specialized solutions to remove:
-
Carbon deposits and soot buildup
-
Gum and varnish from low-quality diesel fuel
-
Microscopic debris affecting spray patterns
After cleaning, we retest the injectors to verify they meet OEM fuel flow and spray pattern standards.
3. Diesel Injector Repairs & Replacement
If an injector is damaged beyond cleaning, we offer:
-
Injector Seal & O-Ring Replacement – Prevents leaks and maintains proper fuel pressure.
-
Solenoid & Electrical Repairs – Ensures precise injector timing and operation.
-
High-Pressure Fuel Line Inspections – Checks for leaks and restrictions affecting injector performance.
-
Complete Injector Replacement (OEM or High-Performance Upgrades) – We install factory-quality or upgraded injectors for better power and fuel efficiency.
We only use OEM-grade or high-performance diesel injectors, ensuring maximum durability and reliability.
Benefits of Diesel Injector Testing & Repair
Restores Power & Fuel Efficiency – Properly functioning injectors improve combustion, throttle response, and MPG.
Reduces Excess Smoke & Emissions – Clean injectors improve fuel atomization, leading to cleaner burns and fewer emissions.
Prevents Costly Engine Damage – Addressing injector issues early prevents piston damage, turbo failure, and excessive wear.
