\n
\u2022 The following troubleshooting flow chart contains the fuel system diagnosis and repair procedures. Read the following warnings before performing the fuel system services:<\/div>\n
\n
\n
\u2015 Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.<\/div>\n
\u2015 Highly pressurized fuel may spray out if the fuel line is cut. Due to the following dangers occurring with a fuel spray, always complete the \u201cFuel Line Safety Procedure\u201d to prevent the fuel from spraying. (See BEFORE SERVICE PRECAUTION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))]<\/a>.) (See BEFORE SERVICE PRECAUTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]<\/a>.)<\/div>\n
\n
\n
\u2022 Fuel may cause irritation if it comes in contact with skin and eyes.<\/div>\n
\u2022 If fuel ignites and causes a fire, it may lead to serious injury or death, and damage to property and facilities.<\/div>\n<\/dd>\n<\/dl>\n
\u2015 Fuel is highly flammable and dangerous. Fuel line spills and leakage can cause serious injury or death, and damage to equipment. Always refer to the \u201cQuick Release Connector Removal\/Installation (fuel system)\u201d before performing the fuel hose installation, and execute the \u201cFuel Leakage Inspection\u201d after installation. (See QUICK RELEASE CONNECTOR (FUEL SYSTEM) REMOVAL\/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))]<\/a>.) (See QUICK RELEASE CONNECTOR (FUEL SYSTEM) REMOVAL\/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))]<\/a>.)

\n
\n
Caution<\/div>\n<\/dd>\n
\n
\u2022 Disconnecting\/connecting the quick release connector without cleaning it may possibly cause damage to the fuel pipe and quick release connector. Always clean the quick release connector joint area before disconnecting\/connecting, and make sure that it is free of foreign material.<\/div>\n<\/dd>\n<\/dl>\n<\/td>\n<\/tr>\n
