Our Kohler 8kW generator uses a Yanmar 3TNE74C-EKM. It has a hard start issue that is very hard to diagnose. It takes 6-8 attempts to start and getting worse. When it finally starts it runs great with no smoke or unburned fuel in the exhaust. Following is a list of things that have been done in a failed attempt to diagnose the issue:
- Injectors rebuilt
- Fuel solenoid tested
- Fuel pressure tested
- Fuel pump replaced
- Fuel lines replaced
- Fuel valve packing tightened at the tank
- Primary and secondary fuel filters replaced
- 12V wiring tested
Has anyone else had this issue and what did you do to correct it? Thanks for the help.
