^ Observe Service Precautions to avoid fuel spillage and injury.

^ Check injectors for leakage and flow rate, using Rotunda Injector Tester 113-OOOO1 and Rotunda Fuel Pump Check Valve Pressure Regulator and Injector Leakage Tool 113-00010, SBDS Injector Flow Tester or equivalent.

^ Does the system maintain fuel pressure and is flow rate for individual injectors within specification?

YES -- Check fuel lines for leaks. If OK, replace fuel pump. Reconnect all components. Repeat Test Step FDS2 for verification. FDS2 - Fuel Pressure Test

NO -- Replace the defective injectors as required. Repeat Test Step FDS14. Repeat Test Step FDS3 for verification. FDS3 - Check Fuel Pressure Leakdown
