The engine normally starts fine and will run all day, but sometimes after shutoff will not start. Cranks great, but no fuel. when at shutdown the electrical solenoid pulls the shut down
valve into the injector housing cutting fuel. When the solenoid releases the valve doesn't return. Tapping the housing will jar it loose and we're back to a normal start.
Has anyone else come across the problem? Does anyone know how to fix this problem?
