Complex Vehicle Diagnostics in Pueblo, Colorado
Advanced Diesel Engine & Performance Diagnostics
At Divine Fleet & Auto Repair, we specialize in complex vehicle diagnostics for light, medium, and heavy-duty diesel trucks. When standard troubleshooting isn't enough, our expert diesel mechanics use advanced diagnostic tools to pinpoint hard-to-detect performance issues, ensuring your engine, fuel system, and drivetrain are running at peak efficiency.
Modern diesel trucks rely on precise fuel delivery, airflow management, and mechanical synchronization to function properly. Even minor inefficiencies can cause performance loss, reduced fuel economy, excessive smoke, or drivability issues. Our comprehensive diagnostic approach helps identify and resolve these problems before they lead to major repairs or breakdowns.

When Do You Need Complex Diagnostics?
If your truck is experiencing any of the following hard-to-diagnose symptoms, it’s time for a professional vehicle diagnostic service:
Reduced Power & Poor Acceleration – Often linked to fuel pressure inconsistencies, turbo inefficiencies, or sensor malfunctions.
Excessive Smoke (Black, White, or Blue) – Can indicate air-fuel ratio problems, injector issues, or turbo system failures.
Unusual Engine Noises (Knocking or Ticking) – May be caused by timing deviations, internal wear, or fuel system problems.
Frequent Regeneration Cycles (DPF Issues) – If your diesel particulate filter (DPF) is clogging too often, there may be inefficiencies in the combustion process.
Rough Idle & Stalling – Common with fuel pressure variations, air intake restrictions, or injector failures.
High Fuel Consumption – Often results from inefficient combustion, failing sensors, or unoptimized fuel injectors.
Excessive Engine Vibration – Can be caused by misfiring cylinders, imbalance in the drivetrain, or worn-out mounts.
If you’ve replaced parts, performed maintenance, and still experience performance issues, our advanced diagnostic process will uncover the root cause.
Our Advanced Diesel Diagnostic Process
Unlike basic code scanning, our approach involves deep-level system analysis, using cutting-edge diagnostic equipment to evaluate your truck’s engine health, fuel system efficiency, turbo performance, and emissions system functionality.

1. Engine Performance Evaluation
-
Compression Testing – Verifies cylinder health and combustion efficiency.
-
Turbo System Inspection – Checks for boost leaks, turbo lag, and wastegate functionality.
-
Air Intake & Fuel Mixture Analysis – Ensures proper air-to-fuel ratios for maximum efficiency.
-
Exhaust Flow & DPF Monitoring – Detects blockages, backpressure issues, or improper regeneration cycles.
2. Fuel System Diagnostics
-
Fuel Rail Pressure Testing – Identifies weak fuel pumps, faulty regulators, or injector return leaks.
-
Injector Flow Testing & Balance Rates – Measures fuel delivery precision to prevent misfires or over-fueling.
-
EGR System Efficiency Testing – Ensures the exhaust gas recirculation system is working correctly to prevent power loss.
3. Drivetrain & Engine Load Testing
-
Powertrain Efficiency Analysis – Evaluates torque delivery and power output under load.
-
Transmission Shift Pattern Assessment – Identifies irregular shifts, slipping, or torque converter issues.
-
Crankshaft & Camshaft Timing Validation – Ensures proper synchronization to prevent detonation or misfiring.
Why Complex Diagnostics Matter
If you experience any of the following issues, your engine may need a full rebuild:
Prevents Unnecessary Part Replacements – Avoid replacing expensive components without knowing the real cause of the problem.
Optimizes Fuel Economy – Identifies inefficiencies that increase fuel costs.
Extends Engine & Drivetrain Life – Early detection of mechanical issues prevents major repairs and downtime.
Improves Towing & Heavy-Load Performance – Ensures your truck is delivering maximum power under load.
Reduces Downtime for Fleet Vehicles – Quickly pinpoint and fix issues to keep your fleet running efficiently.
