Everyone was professional and super friendly. I went in for an inspection for my class b rv. They were quick! And had good choice of keurig coffee pods while I waited. I will definitely go back to them for other services when needed! Thanks!

Royce Clark II

As a new owner operator, I am very skeptical about prices and procedures. The staff at TLC understood that and comforted me the whole way. Naturally, a lot of explaining had to be done. A staff member named Tyreek helped me and guided me through the whole process. (Two weeks later, and I still remember his name) At the end, I needed a service Done that was not on the invoice. A staff member completed the job and denied my $10 tip. This staff is the greatest!

I had a great experience at TLC Auto. After getting a flat tire I brought in my car. Unfortunately the tire couldn’t be saved, but Dom got my new tire on and balanced in no time. I highly recommend them.

Frequently Asked Questions

What are the signs of a bad diesel injection pump?

Hard starts, loss of power, or excessive exhaust smoke are common warning signs. You might also notice fuel leaks or reduced fuel economy. Schedule a diesel injection pump repair as soon as you notice these symptoms to prevent further damage.

Can a diesel injection pump be repaired instead of replaced?

Yes, many pumps can be repaired rather than replaced. Our technicians rebuild and recalibrate the unit using OEM-quality parts. Repairing your fuel injection pump is often faster and more affordable than full replacement.

What causes a diesel injection pump to fail?

Contaminated fuel, worn seals, or blocked filters are the most common causes. Dirt or rust can disrupt fuel pressure and damage internal components. Regular diesel fuel system service prevents most of these issues.

How much does it cost to repair my diesel injection pump?

The total cost depends on your truck’s make, model, and condition. Most diesel injection pump repairs range between $800 and $1,800. You’ll always receive a clear estimate before any work begins.

What does a diesel fuel injection pump repair involve?

We test the pump for pressure and leaks, remove it, replace damaged components, and recalibrate it for accurate fuel delivery. The system is then refilled and tested to verify proper operation. Each diesel injection pump repair is backed by our up to 5-year / 60K-mile warranty.

How do you maintain the pump after repair for optimum health?

Keep your fuel filters clean and replace them regularly to prevent contamination. Always use clean diesel and avoid running your tank too low, since fuel keeps the pump cool. These steps extend the life of your fuel injection pump repair.

How long does a diesel injection pump last?

A properly maintained injection pump can last over 150,000 miles. Clean fuel and regular filter changes are key to performance. Routine diesel injection pump service prevents early wear and costly repairs.

Do you service all types of diesel engines?

Yes, our certified technicians repair and service all diesel makes and models, including Ford, Freightliner, Volvo, and Mercedes-Benz. We use OEM-level diagnostics for every diesel injection pump repair.
