FUEL SUPPLY
13C-2
GENERAL DESCRIPTION
M1135000100435
• The fuel tank is located under the floor below the
rear seats.
• A fuel cut-off valve is utilized to prevent fuel from
leaking out in the event of a collision.
• A fuel pump module, including fuel pump, fuel fil-
ter, reservoir and fuel level sensor, is used to
lighten weight and improve serviceability.

FUEL SUPPLY DIAGNOSIS
INTRODUCTION
M1135004000388
The fuel system is used to supply an appropriate fuel
mixture to the engine. The system consists of the
fuel tank, fuel filter, fuel pump and fuel pipes. An
evaporative emission system is provided to prevent
evaporated fuel from escaping into the atmosphere.
Engine malfunctions caused by insufficient fuel sup-
ply and evaporative emission system operation mal-
functions can be caused by faults in the vapor line,
fuel pipe, hose, or fuel tank pressure control valve,
etc.
TROUBLESHOOTING STRATEGY
M1135004100277
Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will be sure to find
most of the fuel supply faults.
1. Gather information from the customer.
2. Verify that the condition described by the
customer exists.
3. Find the malfunction by following the Symptom
Chart.
4. Verify malfunction is eliminated.
