Diesel Fuel System & Injector Repair

Precision Diagnostics for Diesel Injectors, Pumps & Fuel Systems

Your diesel’s performance starts with its fuel system. When injectors, pumps, or filters fail, you’ll notice rough running, hard starts, or loss of power. At Rob’s Automotive Repair Center in Clackamas, OR, we specialize in diesel fuel system and injector repair for trucks, vans, and European diesels. If you’re searching for diesel injector repair near me, our team delivers accurate diagnostics and lasting repairs.

Why Diesel Fuel Systems Matter

Diesel engines rely on precise, high-pressure fuel delivery. Even small issues can cause:

  • Hard starting or no-start conditions
  • Poor fuel economy
  • Excessive black or white smoke
  • Power loss under load
  • Rough idle or misfires

That’s why accurate diagnostics and high-quality repairs are critical to protecting your diesel.

Fuel Injector Services

Injectors are a common failure point in modern diesels. We provide:

  • Injector testing & balance rate analysis
  • Replacement & coding for Cummins, Power Stroke, Duramax & European diesels
  • OEM-quality injectors for reliability and longevity

Symptoms like fuel in oil, rough running, or excessive smoke are often traced to injectors—and we know how to fix them right.

Fuel & Injection Pump Repair

The heart of your diesel’s fuel system is its injection pump. When it fails, the truck may run poorly—or not at all. We service:

  • CP3 & CP4 pumps (Duramax & Cummins)
  • VP44 & mechanical pumps on older Cummins and others
  • Lift pump diagnosis & replacement
  • Contaminated fuel cleanup (water, algae, or debris in tanks)

We install only remanufactured or new pumps from trusted suppliers, ensuring your fuel system delivers the right pressure every time.

Preventive Fuel System Maintenance

Routine service helps avoid costly breakdowns. We recommend:

  • Fuel filter changes at proper intervals
  • Tank inspections & cleaning if contamination is suspected
  • Use of quality fuel & additives to protect injectors and pumps
  • Periodic system checks during routine service

Preventive care saves thousands by protecting injectors, pumps, and your engine itself.
