Common Cummins Engine Problems We Fix
Cummins engines are known for durability and power—but like all diesel systems, they require expert care. We frequently diagnose and repair issues such as:
✓ Fuel System Failures
Including injector leaks, pump malfunctions, and fuel contamination.
✓ EGR and DPF Problemss
Emissions-related components like EGR valves and diesel particulate filters often require cleaning, repair, or replacement.
✓ Turbocharger Issues
Loss of power, smoke, or whistling sounds may indicate turbo problems—we handle inspections and replacements.

Critical for engine longevity, we track down causes and prevent future damage.
✓ Sensor or ECM Failures
Modern Cummins engines rely on sensors and modules—we test and replace these to restore system accuracy.
