It isn’t easy keeping your fleet or commercial trucks up and running. At Harold's Used Auto Parts Inc in Philadelphia, PA, we’re here to help. Fleet and commercial vehicles log a lot of miles, and a lot of hours - as a result, even the most reliable components need to be serviced occasionally. On an ordinary diesel, an injection pump may last the entire life of the engine itself. On vehicles that work harder than anything else on the road, this isn’t always the case. 

Injection pumps are durable and reliable components, and as such tend to get neglected as time goes on. However, they are also intricate and precisely engineered, and the way your engine runs is completely dependent on the condition of the injection pump. 

If your diesel is experiencing hard starts, rough idle, or is starved for power, the injection pump might be to blame. Don’t ignore the warning signs of a faulty pump - they’re generally pretty expensive to replace, but if taken care of early enough can often be repaired or rebuilt. Our professional technicians have the equipment and knowledge necessary to diagnose and repair any pump issues you may have.

No matter your maintenance or repair issues, we’ve got you covered. For the best fleet and commercial diesel repair shop in Philadelphia, PA, call or stop by Harold's Used Auto Parts Inc today.
