Rail pressure and injector faults diagnosed, replaced, and correctly coded in-shop.
High-pressure fuel pump and injector service for your Sprinter in Huntington Beach solves hard starting, misfires, rough running, and fuel dilution.

Frequently asked questions
What are the signs of a failing injector?
Hard starting, a rough or shaking idle, misfire codes, black or white smoke, and a rising oil level from fuel dilution. We test injector return flow to find the culprit.
Do new injectors need coding?
Yes. Each injector has a calibration code that must be entered with Xentry so the engine trims fuel correctly. Skipping this causes rough running.
Can one bad injector damage the pump?
A failing injector can send debris through the fuel system. We inspect the system and, when contamination is found, address it so a new pump is not ruined.
Why is my oil level rising?
Leaking injectors can wash fuel past the rings into the oil. We confirm fuel dilution and fix the leak, then change the diluted oil.
