M20C-FKS, M20D-FKS FUEL  FUEL SYSTEM  PRECAUTION  


CAUTION:
·
A360563

Never perform work on fuel system components near any possible ignition sources.

·

Vaporized fuel could ignite, resulting in a serious accident.

·
A360564

Do not perform work on fuel system components without first disconnecting the cable from the negative (-) battery terminal.

·

Sparks could cause vaporized fuel to ignite, resulting in a serious accident.

·
A344817

The fuel tank assembly is very heavy. Be sure to follow the procedure described in the repair manual, or the fuel tank assembly may fall off the engine lifter.

·
A357489

To prevent serious injury due to fuel spray from the high-pressure fuel lines, always discharge fuel system pressure before removing any fuel system components.



BEFORE WORKING ON FUEL SYSTEM



b.

Do not smoke or work near fire when handling the fuel system.


c.

Keep fuel away from rubber or leather parts.



DISCHARGE FUEL SYSTEM PRESSURE


CAUTION:
·

Make sure the engine coolant temperature is 60°C (140°F) or less when performing this procedure.

·

Do not disconnect any part of the fuel system until you have discharged the fuel system pressure.

·

Pressure will still remain in the fuel lines even after performing the following procedure. When disconnecting a fuel line, cover it with a piece of cloth to prevent fuel from spraying or coming out.



a.

When discharging fuel system pressure by disconnecting the fuel pump connector:


ii.
A576254

Disconnect the fuel pump connector.


iii.
A467780

Disconnect the fuel pump assembly connector.


iv.

Start the engine. After the engine has stopped on its own, turn the ignition switch off.

NOTICE:

Do not increase the engine speed or drive the vehicle while waiting for the engine to stop on its own.



v.

Crank the engine again and make sure that the engine does not start.

HINT:

DTC P008700 (Fuel Rail / System Pressure - Too Low) or P017100 (System Too Lean Bank 1) may be stored. Clear the DTCs before proceeding to the next step.
