Information:
Introduction
If the engine turns over but the engine does not start, refer to Operation and Maintenance Manual, "Fuel System - Prime" and Troubleshooting, "Engine Cranks but Will Not Start".If the engine will not start, new service parts are available.The new service parts are the following components.
257-2382 Plug
257-2381 Pin
258-8149 Spring Removal Procedure
Contact with high pressure fuel may cause fluid penetration and burn hazards. High pressure fuel spray may cause a fire hazard. Failure to follow these inspection, maintenance and service instructions may cause personal injury or death.
Ensure that all adjustments and repairs that are carried out to the fuel system are performed by authorised personnel that have the correct training.Before begining ANY work on the fuel system, refer to Operation and Maintenance Manual, "General Hazard Information and High Pressure Fuel Lines" for safety information.Refer to Systems Operation, Testing and Adjusting Manual, "Cleanliness of Fuel System Components" for detailed information on the standards of cleanliness that must be observed during ALL work on the fuel system.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Dispose of all fluids according to local regulations and mandates.
Note: Put identification marks on all hoses and all plastic tube assemblies for installation purposes. Plug all plastic tube assemblies. This helps to prevent fluid loss and this helps to keep contaminants from entering the system.
Turn the fuel supply to the OFF position.
Turn the battery disconnect switch to the OFF position.
