## 🔌 Function

## ⚠️ Common Signs of Failure

-   Difficult starting or failure to start
-   Uneven idle or cylinder misfire
-   Excessive black or white exhaust smoke
-   Diesel leakage from the pump
-   Incorrect injection timing or unstable engine speed

## 🛠️ Service Notes

-   Cleanliness decides whether the job lasts — cap every opening as soon as it is disconnected, work with clean tools, and never let dirt or water into the pump or its lines
-   The pump is a calibrated assembly: do not attempt to alter internal settings on board, and have any testing or calibration done on proper equipment by a qualified shop
-   Set timing and mounting by the procedure in the workshop manual for your engine, and fit new seals, gaskets and sealing washers on refitting
-   Renew the fuel filters and cure the cause of any failure before running a replacement pump; contaminated or watered fuel will destroy the new one too
-   Prime and bleed the system properly before cranking, and note that electronically controlled pumps may need parameters set with Volvo Penta diagnostic equipment before the engine will run correctly
