the inlet side of the filter, verify there are no

issues with fuel inlet restriction or air in the

fuel.

Investigate the cause of the low-pressure fuel system issue.

Repair or replace the damaged component(s).

Engine Will Start - Repair direction priority: ? Fuel inlet restriction. Refer to Procedure

006-020 in the Associated Procedures Table. ? Air in the fuel. Refer to Procedure 006-003 in the Associated Procedures Table. ? Fuel filter restriction - Replace fuel filter. Refer to Procedure 006-015 in the Associated Procedures Table. ? Fuel drain line restriction. Refer to Procedure 006-012 in the Associated Procedures Table. ? Gear pump pressure - Replace the fuel pump. Refer to Procedure 005-016 in the Associated Procedures Table.

Engine Will Not Start - Repair direction priority: ? Fuel System primed. Refer to Procedure

006-015 in the Associated Procedures Table. ? Air in the fuel. Refer to Procedure 006-003 in the Associated Procedures Table. ? Fuel filter restriction - Replace fuel filter. Refer to Procedure 006-015 in the Associated Procedures Table. ? Fuel drain line restriction. Refer to Procedure 006-012 in the Associated Procedures Table. ?

Next Step

Check for excessive fuel leakage from the injectors and high-pressure connectors. ? Refer to Procedure 005-236 in the Associated

Procedures Table.

Injector return flow meets the specification? 4B YES

Injector return flow meets the specification? 6A NO Repair: A cause of this problem could be that the customer is operating on fuels lighter than specified. Fuels with low viscosity result in higher leakage and greater drain flow rates. High injector return flow repair direction priority: ? Verify HPC nut torque. Refer to Procedure

006-052 in the Associated Procedures Table. ? Isolate injector drain flows. Refer to Procedure 005-236 in the Associated Procedures Table. ? Inspect HPC and cylinder head antirotation slot for damage. Refer to Procedure 006-052 in the Associated Procedures Table. ? Inspect injector sealing washer and o-rings for damage. Refer to Procedure 006-026 in the Associated Procedures Table. ? Replace injector. Refer to Procedure 006-026 in the Associated Procedures Table.
