Ignition System: Service Precautions

Ignition System


Fuel lines are under pressure.

Danger of personal injury to eyes and skin.

Wear protective eyewear and protective clothing in order to avoid injury and contact with the skin. Wrap a cloth around the connection before disconnecting a fuel hose. Open the connection carefully and release the pressure.

To reduce the risk of personal injury and/or damage to the fuel injection and ignition system, always observe the following:

• Do not touch or remove ignition wires when the engine is running or turning at starter speed.

• Only disconnect and reconnect wires for the injection and ignition system, including test leads, if the ignition is turned off.

• The fuel pump is activated by turning on the ignition and by a drivers door contact switch. If the battery was not disconnected, the connector - arrow - must be disconnected from the fuel delivery unit or the fuse for the fuel pump control module (J538) must be removed before opening the fuel system.







Note the following whenever working inside the engine compartment due to limited space:

• Route all lines and wires in their original locations.

• Ensure sufficient clearance to all moving or hot components.
