Diesel Fuel Injection

Safety Precautions

CAUTION!
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:

• Route all lines and wires in their original locations.

• Ensure sufficient clearance to all moving or hot components.

Observe the following if test and measuring instruments are required during a test drive:

• Test and measuring instruments must be secured to rear seat and operated by a second person from this location.

If the vehicle is involved in a collision while testing and measuring equipment is operated from the front passenger seat, the person sitting in that seat could be seriously injured when the airbag deploys.

CAUTION!
Secure the scan tool on the rear seat and have a second technician operate it from there.

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

• Only disconnect and reconnect wires for glow plug and fuel injection systems, including test leads, when ignition is turned off.

• If the engine will run at starter speed without starting, disconnect the connector from the fuel pressure regulator valve (N276).

• Obtain the code for anti-theft radios before disconnecting the battery.

• Always turn the ignition off before disconnecting or connecting the battery. Failing to do so could damage the diesel direct injection system control module.
