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
