A unit injector combines pressure generation and injection, so testing covers its hydraulic and control functions. Uneven engine running can involve its drive, wiring or seals as well as the injector itself. Diagnosis is followed by cleaning and inspection to establish possible repairs and required adjustment. The assembled unit then undergoes a final test. Findings are explained alongside installation requirements, because correct unit injector operation also depends on related engine components.
Inspection shows the parts' real condition before repair starts, rather than guessing. A final check after adjustment confirms the pump-injector unit is back within working spec.
