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.

I'm late to review Rob's, as they took care of me back in August, but these guys are amazing!!! Carter was the main employee I spoke with over the phone and he was phenomenal. He also came in on his day off to make sure I had … read more my car secured in a safe place until they opened. Corey also really helped when I came in personally and by going through some paperwork to ensure I wasn't being screwed over by the company I had been going to the last several years (which it turned out i kind of had been). Carter and Corey worked together to find me the best ways to handle the situation and have me honest suggestions without making me feel manipulated into paying for maintenance through they're company - they were there to help and make sure that I was safe while driving my vehicle. While being very professional and knowledgeable, they went up and beyond what I could have hoped for. The company understands that life happens and they do everything (within reason) to work with your time and budget to make sure that their clients are well taken care of and that the work that they do is thorough and accurate.I HIGHLY suggest using Rob's Automotive for your vehicle needs because of their honesty, hard work and their excellent customer service.Thank you again, especially Carter and Corey, for helping me get through a rough time with my little car and helping me feel confident that I made the right choices on how to handle my car issues. I will absolutely be coming back!
