Common symptoms of unit injection pump failure
Hard starting, extended cranking, engine no-start, unstable idle, loss of power, rough running, excessive smoke, increased fuel consumption or fuel-delivery interruptions may indicate a problem in the diesel fuel system. These symptoms may also be caused by clogged fuel filters, a worn injector, contaminated fuel, air in the fuel system, timing issues or other diesel engine management problems. Professional diagnostic testing is strongly recommended before replacing any fuel system component.
Important diagnostic and installation information
Before replacing the unit injection pump, a professional inspection should be performed, including fuel supply and pressure testing, fuel filter inspection, fuel contamination inspection, timing verification and diesel fuel quality analysis. If the previous pump failed due to contamination or internal wear, the injector, fuel lines and fuel filter housing should also be inspected and cleaned before installing the replacement. Installing a new pump into a contaminated fuel system may result in repeat failure.
